Turn on the light test during the day, polar meter H1S Aurora highest flagship projector evaluation

In recent years, although the fierce fighting in the TV market has spawned skills such as 4K surface and Baiji, the former only enhances the exquisiteness and realism of the picture, while the latter can bring us real sensory shocks and stimuli. Tens of thousands of prices simply can not go to the public life. However, people’s pursuit of a big-screen audio-visual feast will not be reduced because of these conditions. Instead, they will become more and more intense. As a result, projectors have gradually moved from commercial use to civilian use. Among them, extremely rice and nuts are among the prominent manufacturers’ representatives.

The early civilian micro-projectors (micro-projectors) were designed to meet the needs of large-screen, small-size, and غير مجاز مي باشدt-effective screens. In some respects, there will always be trade-offs. Until last year, the ultra-fine meter adjustment product line that began to take the lead began targeting “ The core experience of "Sound" has been exerted. The H1 was born at the beginning of 2016. However, it is not the H1, but the H1S Aurora with its upgraded performance.

Continuing the classic, flagship appearance

After experiencing the Z4 series of art routes to seize the market, the pole rice has been the H series flagship since last year. Although it has been a year and a half later, the appearance of H1 has continued to the H1S Aurora.


Has long been out of the "micro-cast" of the body size (202 * 202 * 135mmm), metal-controlled hard faction, carbon crystal ash and matte black color allows the product to reveal a steady stream of professional atmosphere, and H1S aurora color is more Deep, and completely different from the previous literary style, the whole machine revealed a flagship wind, perhaps this is why the H series still retains the original design.


The whole design adopts a rounded quadrangular prism. Two-thirds of the area covers a high-density round corner rectangular opening to provide enough airflow channels for heat dissipation (outside the two sides of the inlet air). It is to ensure that the two Manhattan stereos in the fuselage cavity are released with passion.


The front is a large high-transparent coated glass lens, H1, H1S, H1S Aurora still uses the classic Mimic slide switch, compatible with physical switch and lens protective cover function, and the biggest difference with the H1 is in the lens An HD lens is added on the right side to achieve the auto focus function. From the aspect of industrial design, Jijun does not agree with such a hole design, but the auto focus function must not be missing. This may be the best result after the extreme meter trade-off. .


The top of the fuselage is a matte black plastic panel. The concave design can place some simple objects, but it is not recommended to do so. There is a touch-sensitive media button and a solid player button on the back edge. The use scene is not open. Pure audio mode under the lens,.


All external interfaces are placed on the back of the body, conventional headphones, network cable, USB2.0/3.0, HDMI and other interfaces do not fall, in order to meet the users with a high pursuit of sound quality, the pole meter also added SPDIF and HDMI ARC output interface.

Finally, we must mention the sound system at the bottom of the fuselage, such as the sound system has always been the soft underbelly of projector products, this is not a problem, but the product form and structure of the micro-projection is determined. Because the size of the projector determines that it is impossible to plug the huge sound inside the body, and the tri-band low frequency will cause the body's jitter so that the screen tremble, the best solution is the speaker outside, but Taking into account the integrity of the product must be compromised.


The way the pole meter is built is the suspension of Manhattan. There are two 45mm Harman Kardon loudspeakers clearly visible at the bottom. At the same time, the bass passive diaphragm is added. According to the official statement, it is a 2.1-channel sound system that makes the H1S aurora rich. From the perspective of practical experience, the cooperation between the Mi-meter and Manhattan has really improved the sound quality of the projector products. Compared with those products that are better than nothing, they can meet the daily viewing requirements.


As the current flagship machine with the highest number of meters, no accessories in the paste, two DLP-Link LCD shutter 3D glasses became the standard, the official price of 178 yuan a pair, in addition, in On TV, everyone must have seen Hunan Satellite TV advertising on extremely rice. In fact, Miji and Wang Han have cooperated. Therefore, VIP cards for mangoes are randomly included. According to machine kings, this seems to be the standard for all categories. It is by no means the privilege of the H1S Aurora, and at this point Mami is more conscientious.

Pain points improved, close to commercial


Home projector as a commercial-to-civilian product has far less brightness and resolution than commercial use, and as a digital product in a home scenario, it will not be installed as a professional projector and a sufficient projection distance and optimal projection are reserved. From an angle, these have become pain points for home projectors, and the Polar Aurora H1S will shoulder such a mission, at least in the direction it is.


Some people who have communicated with projectors have made such remarks. The projector screen is often viewed at distances of hundreds of miles, viewing distances of two meters, and rough white walls. These actual environmental factors will make the gap between 720P and 1080P extremely small. There seems to be nothing wrong with watching such rational analysis, but when you really look at the 1080P projection screen, you will not say so. The refinement of the picture and the overall picture quality can be clearly identified by the naked eye. If there are conditions for using the screen, the 1080P picture can be comparable to the 2K TV. This may be the reason why the PMI is the first to upgrade to 1080P.


For the lack of brightness, the initial H1 raised the brightness to 900 ANSI. After experiencing 1100 ANSI H1S in the middle, the H1S Aurora increased the brightness to 1200 ANSI lumens. The direct effect of the brightness increase is even when the indoor light source is adequate. The whitening of the screen has also been quite weak, and the ambient light in the night is extremely dark. Naturally, the quality of the picture at this time does not need to be said. Therefore, the following pictures are real shots with sufficient ambient light.









From the real shot diagram, we can see that despite the influence of ambient light, the whitening of the screen is not serious, within the acceptable normal range, and the overall color is rich and rich in color control. And the color transition will not appear drag and drop phenomenon, the daytime viewing has reached a remarkable point, if you have to give a conclusion, then the polar meter H1S Aurora is a projector that can open windows in the daytime normal viewing.

As a home digital product, the size and layout of each home are not the same. Only positive investment has become a big “bad point” that prevents the normal use of projectors. In fact, it is not such a solution to business use. The technology was only used in star models that غير مجاز مي باشدt more than 10,000 yuan, and this time, the meter's keystone correction functions, which are 45 degrees up and down and 45 degrees left and right, were directly decentralized to civilian projections. Normal projection screens can also be obtained with oblique launch. Perhaps the language is pale, refer to the following picture.


As a flagship performance enhancement product, the Polar Aurora H1S Aurora boosted its brightness from 900 ANSI to 1200 ANSI, and its resolution increased from 720 to 1080P. Combined with a keystone function of up and down 45° and 45° left and right, the current family was solved once. The three major pain points of the projector are satisfied with the positioning of the H-series products by the Extreme Meters, and are also satisfied with the expectations of the users for the projectors.

Minimal interaction, suitable for all ages

As the old saying goes, there are old ones, there are small ones, and any family technology products are not just about young people. Serving the elderly and children in good homes is the key. Friendly human-computer interaction has become a real issue in this era.


At this point, Ji Jun highly agrees with the UI design of the Kamitsu. The OS used by the Aurora H1S Aurora is GMUI 2.0. Based on the Android 5.1 development, as a common sense, Android is a vertical screen system, but the projector is a horizontal screen system. The first optimization is vertical screen horizontal screen, which has already been planned.

In addition, GMUI2.0 adopts a minimalist design style. On the left is a Metro similar to Win8. Its clear colors and card-like large icon structure are concise and clear, namely, movies, music, games, and applications. To the right is similar. All Android applications, users can install their own favorite applications or games, the entire operation process is simple, interactive humanity.


In terms of film sources, the Mi projector is just a platform product, but it integrates the two mainstream video libraries of Mango and iQiyi, and the resources can meet the needs of a wide range of users. Of course, users can also install applications on their own.

Summary: Clear Positioning

The positioning of H1S Aurora is clear. It solves the pain points of products left over from price wars and artistic eras. It aims to enhance the brightness and resolution of home projectors and to align with commercial projectors. It also advertises the ambitious ambitions of the polar meters. In fact, it is Shenzhen Science and Technology. In the garden, you will inadvertently see some restaurants and bars equipped with Mi-H series products. Perhaps this is the most powerful proof of the pain points.


As the leader of micro-investment industry, the product positioning of this product will undoubtedly help friends quickly align themselves, improve the product line of high-brightness, high-resolution projectors, and lead the projector's product direction, which is also a The demeanor that the big factory should have, and this kind of ending is also what we ordinary consumers would like to see. Finally, the price of Aurora H1S Aurora is 5,999 yuan. Although it is not cheap, it is more expensive than Bai TV or laser TV. This is the best choice among big screens in the same price range.

Value Analysis of Product Culture in Packaging Design (1)

[Abstract] Commodity culture is the sum of various cultural elements based on commodities. It is both economic and cultural as well as social and cultural. This article focuses on the economic and cultural characteristics of commodity culture, and elaborates that the packaging design of commodities should create the use of commodity culture. Value creates the value and cultural added value of commodity culture, thereby enhancing the cultural taste of the commodity and artistically increasing the economic value of the commodity.

[Key words] commodity culture; packaging design; value; use value; cultural added value

"Creation" is originally a construction term, mainly referring to the "construction" and "fabrication" of a building. This article is used as a verb and can be understood as "business" or "creation." Commodity culture is the sum of all kinds of cultural elements based on commodities. It is both economic and cultural as well as social and cultural. The packaging design of the product culture, it includes two layers of meaning: refers to the choice of the cultural elements of the product, identification, integration into the packaging design; also refers to the cultural tradition is not obvious goods, artificial creation of culture, two Harmony and unity. It is mainly reflected in the use value, value and cultural added value of commodity culture.

First, create the use value of commodity culture

The use value of commodity culture refers to a certain attribute that product culture can meet people's needs. American quality expert Dr. Milan pointed out: "Quality is practicality" refers to the use value of goods, so packaging design should pursue "integrity of the packaging is the best strategy", that is, product quality and design must meet the characteristics of the content, grade , and can not use packaging to mislead consumers. At present, in the increasingly mature and exquisite packaging of various kinds of goods, we still find it difficult to find some flashy, lack of integrity of the packaging design. For example: A certain brand of powdered packaging, its packaging design and decoration design looks pretty good, but it has placed a large piece of white foam plastic, which put two empty bottles with poor shape, poor quality, Only a small plastic bag is packaged, and it does not add up to half the capacity displayed on the outer cover. These large pieces of foam and empty glass bottles, which do not play a role in protecting the goods and promoting consumption, not only increase the amount of waste that is harmful to the environment, but also cause consumers to resent the hypocrisy of the packaging. In addition, there are packaging packages and goods are not appropriate, text content is inaccurate, misuse of advertising language, and some other deceptive packaging, is also common in the mall. These lack of integrity of the packaging may be able to confuse consumers for a time to achieve the purpose of sales, but the loss is undoubtedly more business opportunities, greater interests, therefore, the integrity of service is the basic rules of modern packaging design should follow. This will not only help establish the image and reputation of commodities and enterprises, achieve the purpose of developing business opportunities, but also help maintain business ethics and order, enable the socialist market economy to develop healthily, and play a good role in commodity trade.

Along with the rapid development of the market economy, commodity packaging not only plays the role of wrapping and protecting commodities, but also bears the heavy responsibility of actively promoting and selling products. People often use it to understand commodities and understand the commodities. The packaging of commodities undoubtedly becomes an attractive consumer. And to impress consumers with the key factors. In this way, how to achieve honest service has become a goal that must be valued and pursued in packaging design. To achieve integrity in packaging design, we must emphasize people-oriented and give people convenience. Specifically, we must first design from the convenience of product display, use, and recycling. Japan’s Suntory’s can of beer can be folded according to the instructions on its packaging after recycling to facilitate recycling; followed by the normative packaging design. Commercial game planning, the need for standardized design, packaging should be fully detailed description and verification data, there should be no false words, foreign packaging will appear on such a phrase: "Please eat after freezing," "Do not do Other uses", "warning, contain nuts, stay away from young children." In particular, today's goods are becoming more internationalized. Packaging design requires more regulation to avoid unnecessary troubles. Once again, it is public welfare. In the 1980s, British packaging was marked with “Children say no to danger!” US packaging superscript There is "to prevent drugs!" Even the face of lost children is printed on the side of milk packaging. The purpose of doing so is to effectively protect the interests of consumers, but also become the selling point of the goods. The formulation of packaging design to create the use value of commodity culture was earlier, but in the new market conditions, people have new requirements for them. They are the indispensable unity of the commodity culture, so the packaging design is the product culture. The creation of connotation has a very realistic meaning for consumers to enjoy "good and cheap" goods.

Mexican government will announce energy reform proposals soon

According to overseas media reports on March 8, Mexican Senator Ruben Camarillo said on March 6 that the ruling Conservative Party of Mexico will soon announce a plan to allow Mexican state oil giant Pemex to develop the Gulf of Mexico Energy reform proposals for crude oil reserves in deep water areas.
Camarillo told reporters at the El Universal newspaper that the bill will be separate from reform measures that may come from President Calderon or from possible reforms in the Senate Energy Committee.
Pemex hopes to make up for potential declines in the country's very large but aging Cantalel oilfields by developing potential deep-water fields.
However, Pemex lacks the know-how and know-how of working in deeper waters, and industry analysts believe that Mexico’s laws have prevented private companies from working with Pemex to conduct oil and gas exploration operations in deep waters in the Gulf of Mexico.
Camarillo, who served as Secretary of the Senate Energy Committee, said: "The reform we will propose will involve how we can solve this deep-water problem and how we can enter new oil and gas reservoirs that are 2,000 meters to 2,500 meters deep."
Some opposition legislators have completely ruled out changes in law in the past few weeks, and analysts say these changes are necessary to allow Pemex to enter deep-water fields.
The opposition’s tough stance on this issue will be enough to overturn any deepwater proposals, because Calderon’s political parties cannot get the support of most legislators in the parliament.

How to streamline HD monitoring data storage mode

With the arrival of the era of high-definition surveillance, the غير مجاز مي باشدt of the entire video surveillance system began to increase significantly. Among these, not only is the غير مجاز مي باشدt of front-end HD cameras increased, but the غير مجاز مي باشدt of back-end storage devices has risen dramatically as image clarity has increased from SD to HD. The data shows that when using traditional DVR and NVR solutions, the غير مجاز مي باشدt of storage devices in the entire video surveillance system is roughly 15% to 30%; while in digital network high-definition video surveillance systems, the غير مجاز مي باشدt of storage devices in the entire system is Will rise to 50% to 70%.

This is not a sensational statement. Taking the HD basic 720P effect as an example, the normal hard disk capacity required for video surveillance is about 4G~8G/hour. For economic reasons, reducing the hourly video recording can be reduced to about 3GB. capacity. Taking this as an example, eight-way monitoring is about 17T capacity by one month calculation. According to the relevant regulations, surveillance video in public places needs to be kept for at least one month (30 days) or longer, and in some places for a longer period of time, the mass data storage problems caused by this can be imagined.

So, what can be done to reduce غير مجاز مي باشدts on the basis of expanding storage? The following are some common ways to reduce storage space for your reference.

Choose the right codec

If you upgrade the encoding format from MJPEG to H.264, you can save more than 50% of the storage space. Because of this, more and more end-users are starting to upgrade their data formats from MJPEG and MPEG-4 to H.264, allowing compressed video to take up less space while maintaining the same video quality as MPEG-4.

A typical frame (R frame) is selected in the video sequence, and the end user can choose to store only R frames. By using R frames and compressing video streams in H.264 format, video streams can be generated with lower bandwidth and more efficiently. This situation is useful for most cameras. For example, for a fixed camera that monitors a few moving targets at an airport terminal or for a continuously rotating camera like PTZ, the resulting R frame increases.

In some cases, the video quality provided by the H.264 compression method is only better than the video quality provided by the MJPEG compression method at the border, but because the H.264 compression method occupies lower bandwidth. Therefore, recording video data takes up less storage space.

In general, in most monitoring systems, H.264 is an efficient codec in terms of reducing bandwidth and storage space.

Idle time to reduce the recording rate

We all know that in places like office buildings and schools, there are few people appearing at night, but the cameras are working as usual. The recorded videos do not have any effect at all and they also occupy storage space. Therefore, we can consider lowering the recording rate during periods when there are few moving targets by controlling the recording rate. For example, 15 frames per second may occupy a large amount of storage space. At this time, it is possible to use 2 to 3 frames per second, or even 1 frame per second. Rate recording, the end user can save up to 80% of the recording space.

However, although there are few pedestrians in the building during the night, many meeting rooms are not used during most of the time. If these occasions have been recording video at a low rate, what if there is an alarm? We can consider adding to the monitoring system. The basic intelligent motion analysis function, if there is a moving target, the recording frame rate will return to the normal rate; when the moving object disappears, the recording rate will return to 2 to 3 frames per second, which will not only reduce the storage space Can also play a role in monitoring alarms.

Do not record unwanted content

The above method is mainly for the monitoring area is mainly static type, the number of monitoring targets is not much, but if for the road, elevator and other places where people come and go, we cannot use the above method to reduce the recording rate. In this case, is there a feasible solution?

At this time, we can consider adding a basic motion analysis software package to the monitoring system. For some moving objects, we do not need to record their videos. For example, when a car drives down a road, we don't need to record the whereabouts of the car. When the trees sway in the wind, they don't need to record; if this happens, they are also recorded, like the surveillance perimeter. It is necessary to keep recording, so the storage space consumed can be imagined.

According to relevant statistics, for some cameras, the areas that are not required to monitor moving targets in the surveillance area can save up to 50% of storage space.

Fixed rate decimation frame storage technology

According to the current mainstream compression method, the required space for surveillance video storage is as follows:

H.264 compression method: HAFLD1 resolution, real-time 25 frames, 300M/hour/road;

H.264 compression method: CIF clarity, real-time 25 frames, 200M/hour/road;

Based on the above data, we can basically estimate the storage space required for all the video surveillance images. For example, a bank needs a 1-channel D1 video surveillance system, 7*24 hours of monitoring, data can be covered in 3 months, then the total capacity needs 1.1TB.

If the video we already have is not as important as the new video, we can reduce the recording frame rate of the old video. This can greatly reduce the need for old video storage space. At the same time, old video can still be used as evidence if needed.

Using fixed-rate decimation frame storage technology, such as 25-frame/s video files stored within one month, can be reduced to 15 frames/s without affecting video recording information, which can also greatly save storage. space.

Plano Convex Cylindrical Lens

Plano-convex cylindrical lenses feature a single plano and single convex cylindrical surface, while their focal length is positive. These lenses operate only in one dimension rather than two, compared to plano-convex spherical lenses.

Plano convex cylindrical lenses are utilized to compress light in 1 axis.  In order to generate a line image from a point of light and to change the aspect ratio of an image, a positive (convex) Cylindrical Lens is used.   It is also applied to focus collimated input light to a line.  Plano convex cylindrical lenses are normally used for line detector arrays, anamorphic beam shaping, laser projection, laser line focusing, and illumination of slit.

How to maximize RFID reading efficiency

In the current management identification technology, biometrics and non-contact recognition are arguably the hottest two identification technologies. When it comes to the advantages of no-touch recognition, I am afraid that the help he has brought to us is obvious to all. Whether it is the current simple and common one-card technology or access control cards related to access control security, it seems that the RFID technology is not against the background. It can be said that in the era of this card rampant, if there is no RF card management device, I am afraid it is difficult to be understood as living in the current information age.

However, while we enjoy the convenience that recognition technology brings to us, there are many annoyances that plague our trust in related technologies. Among them, the success rate of information authentication is probably one of our most headache bottlenecks, and even because of this limitation, it has also greatly affected the popularity of identification technology in our lives. So, how can we improve the recognition success rate of RFID technology as much as possible?

In fact, for RFID technology, its organizational principles and composition are not as complex as we imagine. After the chip card with the magnetic stripe itself enters the radiation area of ​​the magnetic field, the receiver will capture the signal sent by the magnetic card at the signal, and respond to the magnetic field with a radio frequency signal. Afterwards, the data sent by the energy stored in the inductive current is used to realize the interpretation and decoding of the reader, and finally sent to a general control information processing system for signal processing.

Structurally speaking, a complete RFID system consists of three parts: a reader, an electronic tag, and a software system. On the principle of the structure, the reader is responsible for the transmission frequency, and the radio wave energy is used for the signal. The electronic tag is passed to the electronic memo to send the internal data. Then, the reader can respond to the program according to the received signal.

At present, with RFID readers and electronic tags working, RFID devices can be subdivided into inductive coupling devices and backscatter coupling devices. In general, most low-frequency RFID devices use inductive coupling. For high-frequency RFID sensors, there is more scattering coupling.

Why is RFID difficult to identify?

At present, with the increasing use of RFID, the failure of RFID reading or misreading also increases. Through summary, it is found that the misreading of RFID devices is mainly attributed to the following reasons: the mutual interference of readers; the reader has a certain blind area when reading data; there are redundant data at different reading points and so on.

RFID identification card

First of all, the reader's interference, because nowadays with the increasingly widespread use of magnetic cards, we have more and more magnetic identification devices in our hands or in our living environment. When these devices appear in one environment at the same time, different signal conflicts occur. More serious, it may also cause some damage to the surrounding magnetic field, so that the card loses its role. In the initial period of the trial of the bus card in Beijing, there was a case where the magnetic force of the bus card was too strong and the other cards in the same wallet were effective. This situation still plagues the application of some cards.

In addition, there is a problem that there is a redundant area in the reading area or a different reading point. This problem is actually more caused by a defect or mistake in software or system design. As a result, data redundancy or data loss may occur during the reading of the card. This is one of the reasons why the current partial recognition system cannot read the card normally.

How to maximize RFID reading efficiency

As mentioned above, due to interference and its own design flaws, the RFID device often fails to read correctly, which affects everyone's interest in it. How can we solve this problem?

Reasonable configuration build

When building an RFID system, in order to make us more convenient in use, we must first ensure that the system is optimized during construction. For example, at the beginning of construction, the most important thing we need to clarify is our demand for use rather than the blind pursuit of advancement or the pursuit of popularization. Relative to the economic effect and the brand's new trend, good use is the biggest benefit.

Therefore, in the network construction, all RFID cards and system terminals should be regarded as a complete application system. For situations in which blind spots appear, resulting in missed reading, the situation of blind spots existing in the reading area can be compensated by using an increase in the reader or the antenna to ensure the completeness and correctness of device reading.

In addition, for the problem of mutual interference, it is possible to use equipments and the like equipped with isolation devices at the periphery of the equipment to avoid mutual influences and minimize negative effects. In addition, for some environments where the surrounding environment is relatively complex and there are many electromagnetic devices, proper adjustment of the receiving device layout, or the strength of the transmission power, etc., are also important means for solving the related problems.

Further improved software design

For the reason that the RFID reading rate is difficult to increase, it is largely due to defects in the design of the software system. Therefore, it is very important to check the software link.

As mentioned above, the problem of missed reading of some information can be carried out with a reasonable mix of adjustment systems. For the conflict of electronic tags, in the application of some high frequency bands, the ALOHA protocol is generally used to prevent conflicts. In addition, software optimization settings are also one of the effective ways to avoid conflicts. For example, the user can automatically adjust to an adaptive scanning mode according to the frequency of use of the scanning device. When the demand is large, the scanning device can be accelerated by the software. If not, the operating frequency is reduced, so that it can maintain an optimal state at the moment. It can neither miss the reading nor miss the scanning, and also avoids The emergence of redundancy. It also makes the equipment reach a more reasonable working condition.

Technology convergence to solve greater demand

In recent years, the application of RFID has gradually become a trend. However, some distance restrictions have become an obstacle to the development of this technology. Therefore, integration has become a major development direction for RFID to improve work efficiency. For example, the integration of RFID and WSID is actually a very successful attempt. With the continuous application, the integration of technologies such as 3G, GPS, and GPRS will become a necessary requirement for improving RFID applications.

In addition, as biometrics become more widespread today, the introduction of biotechnology will also become the most modern complement of identification technology. Implement basic information retrieval and troubleshooting with personal characteristics. While further facilitating the use, it also makes our identification technology more accurate and secure.

With the continuous advancement of our informatization applications, RFID has become an increasingly essential technology in our lives. As for some problems that appear in the application, we should also face it with a positive attitude to solve it. And we still have to believe that with the gradual realization of planning, software, and convergence, the availability of RFID technology will be substantially upgraded. And our lives will also enter a new era of intelligent recognition.

Goldman Sachs predicts that the price of 100 yuan will come true and predicts that oil prices will double in the future.

The current height of international oil prices is an eye-popping 6 per barrel. On the 7th, US time, the New York crude oil futures price hit a record high of 6.54 a barrel, followed by a slight decline and finally closed above 5 a barrel.
The “reason” for the oil price upside on the 7th day was the report on the reduction of non-agricultural employment in the United States in February. This raised concerns that the risk of a US economic downturn is increasing, and the Fed may continue to cut interest rates. The famous investment bank Goldman Sachs three years ago, "madman's slang phrase" this statement into a bath? In March 005, when the international oil price is still about 47 US dollars, Goldman Sachs analysts predicted that oil prices will rush to 105 US dollars.
But if this price has shocked you now, then you may be prepared to take on greater psychological challenges.
Investment guru Rogers said in Singapore a few days ago that the price of oil may also rise very high, but it is not known to what extent. He also warned that the global inflation situation will become more serious. "Everybody has to be prepared and everything will go up," Rogers said. If the Middle East wars, oil prices will rise to 0 a barrel.
EU Energy Commissioner Pierre Bagges also half-jokingly told the outside world that in 2011 international oil prices may climb to 200 US dollars per barrel. Because oil prices have doubled in the three years since 2004. "A part of what I'm talking about is a joke, but that's nothing strange," said Pierre Bagges. He specifically mentioned that when the famous investment bank Goldman Sachs predicted that the price of oil might be broken three years ago, everyone thought it was a joke.
At the same time, Goldman Sachs once again made a terrible prediction, saying on Friday that in the event of an "emergency," international oil prices may rise to 0 a barrel in the near future. Goldman Sachs also raised the lower limit of the oil price fluctuation range from 2008 to 2012 by US to US per barrel.
Of course, the "Goldmans" are no longer considered "radical elements" in the oil price forecast. According to CNBC television reported on March 8th, Matt Simmons, chairman of the famous energy investment bank Simmons, said in an interview with the TV station “Fast Money” that the international crude oil price may rise to US8 per barrel. Simmons said that the United States has never had a better understanding of the value of crude oil. He pointed out that the British crude oil price has reached 9 US dollars per gallon, which means that the price per barrel is as high as 378 US dollars.
The prediction made by Goldman Sachs in March 2005 that “oil prices will rush to 105 US dollars” has now become a reality.

Color explosion OLED quantum dot technology has been improved

Quantum Materials, a North American manufacturer of quantum dots, recently announced that its quantum yield of pure red (630nm emission peaks) without quantum dots has reached 99.5%. The company also pointed out that its free-standing quantum dots have lasted up to 1,000 hours in remote LED applications. Quantum Materials has achieved 99.5% quantum efficiency and over 1000 hours of continuous operation.


Quantum Materials stated that its pure red (630nm) free quantum dots offer the highest photon conversion efficiency in the industry. The company said that its pure red quantum dots are more effective than quantum dots made with **. The company uses its proprietary continuous-flow manufacturing method to create pure red free quantum dots.
According to the company, its continuous process ensures high homogeneity in mass production. It is worth noting that OLED displays have greater contrast and overall color gamut than LCDs. The OLED screen uses a single luminous pixel as its own light source. OLED displays differ from LCD technology in that LCD technology is transmissive and uses backlight technology.
Because OLEDs are thin, OLED displays do not require backlights, so they can significantly increase power efficiency and enable thinner displays. In addition, since the backlight source is not required, the theoretical response time is 100 times higher than that of the modern liquid crystal display, and the response time is 0.01 milliseconds.
The company said that true QD-LED displays are more powerful than OLED displays with a resolution of up to 1,000 pixels per inch. The company stated that quantum dots can be easily integrated into existing photoresist film layers and are currently collaborating with expert partners to make photoresist films. The shape factor of the QD-LED display is more suitable for mobile devices and quantum dots, so phosphor replacement will completely improve the color performance and energy efficiency of the existing OLED technology. ”

The sofa butler tells you to buy a TV box to see these points.

When many friends buy smart TV boxes, they don’t know how to choose and buy TV boxes. What are the points from which TV boxes should be picked up? Now Xiaobian gives everyone a few strokes.

First, the network receiving ability is strong, the video can be played smoothly



The TV box is connected to the network to watch live video. Therefore, having a stable and reliable speed is a prerequisite. However, with the fixed home network environment, the box's own network capabilities are very important. A box can only guarantee the viewing experience if it has a strong network reception capability. In addition, it is worth mentioning that many of the cottage's machine is an external antenna, in fact, many are false, we need to see it, in fact, many of the built-in antenna network reception capacity is not bad, oh. For example, many big brands like Xiaomi, Huawei, and Tmall are all built-in antennas.

Second, firmware will continue to upgrade, the box can advance with the times


As we all know, basically a lot of mobile phone systems will have a push update package, in order to repair the system's BUG or add some new features, then the box is the same, only continuously updated, continue to provide continuous technical support, regular online update version, can Make the box continue to change the pace of the times. The TV box is not expensive, but if you buy it right, it can still be used in the last three years.

Third, the box cooling capacity, can guarantee long life


When you use a box to watch a movie, a TV show, or play a game, your box's CPU will run. Like a computer, cpu resistors generate a lot of heat during operation. If the cooling capacity is not strong enough, the box will be hot and hot, not only affect the effect of our viewing, but also affect the life of the box.

Four: Directly install third-party software

The biggest advantage of the TV box is that you can install third-party software. For example, you want to watch TV live, or you can use a free movie on demand to install a sofa butler. However, if this function is limited, the box game will be played less.
