Laser Television Industry Revolution
Since the beginning of the year, the domestic color TV industry has been shrouded in the gloom of a sharp drop in sales, but we also see laser TVs have risen in the negative direction, and development has been particularly rapid. Judging from the selective trend of large-screen TVs, consumers are interested in large-screen solutions for laser televisions. The sales of 65-inch TVs have grown faster than mainstream 55-inch TVs. It is well known that the price of 100-inch laser TVs is only 1/10 of traditionally backlit flat-screen TVs. In the past two years, cooperation efforts between core laser display technology companies and Internet brands have also introduced laser television into the million-dollar consumer sector, again tearing the laser TV market apart.
Laser TV has only used more than a decade of time from experimentation to industrialization. It has only taken a few years from the commercial and engineering fields to the home area. Although the sales volume of LCD TVs reached 40 million units last year, domestic shipments of domestic laser projectors (including laser TVs) have only reached 100,000 units, and the market has not yet exceeded 10 billion. However, this trend is shifting. The long-awaited eruption of the laser television market in the next two years has long been a time when laser and liquid crystal disputes are already filled with rumors.
The technology, application, content, service and product landing modes of laser televisions have matured. The industrialized production of core materials and devices and the improvement of supporting industries have led to a gradual reduction in laser semiconductor غير مجاز مي باشدts, coupled with interface, voice, and somatosensory sensations. With the continuous integration of interactive experiences, we believe that the future of laser television will surely make an incredible revolution in the traditional TV market.
After missing the kinescope display and flat panel display, China has already occupied a place in the international laser display industry. Although the civilian field of laser light sources has matured, we must recognize that laser projection TVs are still in the early stages of development. There are not enough market scales and leading brands. The market concentration is not high, and there are relatively more opportunities. In recent years, market brands There may be some new changes in the pattern.
In 2017, the laser TV market ushered in the window of demand growth. In order to witness the take-off of the next billion-dollar smart home market, Smart Home magazine & Smart Headline & Digital Intelligence Network jointly launched the special topic of laser TV applications and solutions. Aggregate upstream display module companies, traditional laser television companies and internet laser TV brands, and talk about the current and future development and landing of laser television. The special topic will interview dozens of industry authorities to elaborate on the sharing of related programs and strive to provide everything Smart home partners enjoy reading.
The concept of science television laser television
The laser television adopts a laser light source projector and a projection screen of reflective ultra-short focal projection technology. It is an ultra-large-screen television, film, and projection integrated multifunctional product. Unlike flat-panel televisions, it can also display in high brightness environments. Very good picture. Laser TV uses a laser as a display light source, and the inherent characteristics (directionality, monochromaticity, and high brightness) of the laser can be used to improve the display of three elements (HD, full-color, true 3D) to the limit of human visual recognition. In addition, laser televisions are generally equipped with intelligent systems. The hardware inside is basically the hardware used by smart TVs. The Android system cooperates with some Mstar chips to realize functions such as playing large blocks online. It can also play games, download applications, and so on.
The English name of the laser television is called LASERTV. Today, LASERTV uses a semiconductor-pumped solid-state laser working substance to generate continuous laser light of three wavelengths of red, green and blue as the light source of the color laser television, and controls the three-primary-color laser scanning image through the television signal. Laser TV is not a traditional LCD technology. Its essence is a cinema TV with ultra-short throw projection technology. The technology overcomes many disadvantages of the projector, such as brightness defects, projection distance limitations, and the life of the light source, and achieves the same uغير مجاز مي باشدe as the ordinary LCD TV, but at the same time, it has the advantage of large size, and can achieve extremely imminent sense of presence. And immersive, in the family can enjoy the effect of theater IMAX, is simply a theater + smart Internet TV.
Its color gamut coverage can theoretically reach more than 90% of the human gamut, which is comparable to the most popular OLED and QLED technologies. The increase in color gamut coverage not only makes the entire TV picture look more realistic, has a sense of depth and transparency, but also enhances the sharpness of the picture with increasing color saturation. Since lasers are used as the backlight for televisions, laser televisions can be made thinner for home use. Laser TV also overcomes the discomfort caused by the long-term viewing of the fluorescent colors produced by the human eye, and it does not radiate to human eyes.
Laser TV advantage inventory
Laser TVs are bright, bright, and flexible in screen size, independent of the directionality of the viewing angle, and bright images can be projected onto various material surfaces, even curved surfaces. The system can also be adapted to all TV standards, such as PAL, NC, SECAM, VGA or HDTV high-definition television, and can be connected to any video source or data source.
The laser is 100% monochromatic light, and the red, green and blue light of the laser television are separately modulated, and the color effect is very satisfactory. Its room-temperature life can reach 100,000 hours in general, and the room-temperature life estimated by the high-temperature aging test can reach millions of hours. Therefore, it is a long-life, high-reliability product, and the general laser television can reach a service life of 20,000 hours. .
Front-projection laser TVs for desktops Because of the small size of the display screen, the laser power is very low and viewing safety. In the case where the power supply and the wireless receiving unit are externally mounted, the host computer can image the size of the cigarette pack.
Security, the red, green and blue three-color visible laser beams in the television are projected onto the screen after special beam expander and shaping equipment. Even if the screen is broken, the laser inadvertently shoots from the screen and will not produce human body. Any adverse effects.
At an optimal viewing distance of 4m to 4.5m, the 30° viewing angle of the screen allows the eye muscles to relax naturally. The screen reflects the reflected light from the laser emitter, which is almost the natural observation mode of the eye, and is comfortable, natural, and innocuous. More suitable for long hours of viewing. According to relevant international standards, laser-based television products are the only display products in the world that fully meet the theoretical vision requirements and are harmless to the naked eye.
Compared with ordinary TVs, under the same screen size and the same image effect, the power consumption is only comparable to that of ordinary TVs. Under the same size conditions, energy consumption is only 1/10 of CRT TV, 1/3 of plasma TV and 1/2 of LCD TV.
Energy-saving and environmental protection, laser processing and production of laser TVs basically do not produce industrial wastewater and other pollution waste, energy consumption is also extremely low.
Traditional projection light sources have short life spans and high energy consumption. Frequent replacement of light bulbs causes huge waste and environmental pollution, which makes the application of projection technology very limited. The power consumption of laser light sources is lower than that of conventional projectors.
The core device of the laser light source is a semiconductor material, which will realize an output ratio that doubles the performance and reduces the غير مجاز مي باشدt by half, and the market has great potential.
The image does not distort. Ordinary projectors are required to be placed as far as they are facing the screen. The laser projector has lenses, which naturally have no distortion. The distortion caused by the oblique projection can be corrected very simply, even if the "projection head" is placed. In the corner, there is no distortion in the projected image. Even a weird projection geometry, such as an arched screen, or even a convex screen, does not deform the laser projection anywhere.
The human eye can see more than 100 kinds of colors in nature, but only 30 kinds can be seen through existing color TVs. Laser TV can see over 70 colors.
High efficiency, the traditional projection bulbs are mostly halogen bulbs, only 2% to 3% of the energy is converted into light energy, the rest are converted into heat, but also afraid of vibration. The laser projection has high luminous efficiency, consumes less power, and does not generate high heat.
The laser has good monochromaticity and high color purity. According to the principle of three-color synthesis, the triangular area formed on the chroma graph is the largest, and it has an irreplaceable advantage compared to other (CRT, LCD, DPD), and it has better resolution than other planes. High, low غير مجاز مي باشدt, small size, light weight.
Laser TV is a laser light source projector and projection screen with reflective ultra-short focal projection technology. It can also display good images in high brightness environments.
Comparing laser television with LED TV, first of all, in image display, lasers with solid-state light sources as LEDs have many advantages in terms of technology, غير مجاز مي باشدt, and leadership, which are inherently incomparable to LEDs. The colors are more vivid and bright. Higher, it also holds the initiative in laser TV technology.
The advantage of laser television is not only in the color reaction, the product is mainly laser, through the optical signal processing, through the light image, the final image. This can basically remove the traditional related components, save some optical devices, the غير مجاز مي باشدt savings is 30% to 40%.
Laser TVs also have inherent advantages in the manufacture of large screens. Compared with the same size LED LCD TVs, the laser light source has a longer life span, the theory can reach more than 100,000 hours, and its power consumption is also lower, which is in line with the social energy conservation and environmental protection needs. The use of ultra-high pressure ** lamp projection only 5000 hours of life.
Laser TV uses a projector with a reflective ultra-short focus technology. This ultra-short focal laser TV can achieve a 100-inch picture within a distance of 0.5 meters. In layman's terms, laser televisions can still project up to 100 inches on TV cabinets, while past projectors need to be hoisted in the middle of the living room.
Many laser televisions support the projection screen function, which means that the contents of your mobile phone can be projected onto the laser television at any time. Under the existing technology, not only videos and photos that are only taken by themselves, many APPs support the screen-casting function. For example, if a user purchases an iQIYi member, he or she can use the iQIYi mobile app to select VIP content and then cast it to a laser TV. This application is very convenient.
Many consumers have been worried that laser television will hurt children's eyes and affect their children's vision. In response to this phenomenon, the brand has launched smart applications that sense human body. As long as people put their heads in front of the lens of the laser television, the laser television will be automatically shut down. Even if the children in the home are naughty, there will be no situation where the eyes look directly at the laser.
Shortcomings
Core components to be broken
Lasers are the most expensive and core components of laser display systems. With the use of semiconductor materials, how to reduce غير مجاز مي باشدts will be an urgent problem to be solved in the laser television industrialization. On the other hand, due to the influence of volume and technology, domestic semiconductor light source technology needs further improvement.
Industrial competition is fierce
LCD TVs are in the limelight, and the scale of industrialization of laser televisions is still unable to compete with LCDs or LEDs. It is still difficult to scale down غير مجاز مي باشدts.
Ultrathin is still a challenge
Since the laser television adopts a transmissive type, although the screen is very thin, the laser transmitter still has a certain thickness, and the larger the screen size is, the larger the thickness is, and it cannot be as thin as the LED liquid crystal television. Although laser televisions can easily be of the same size as LCD TVs, there are intrinsic imaging principles with laser televisions that make it impossible for laser televisions to be as space-saving as flat-panel televisions. There must be an external projection device for laser televisions. In front of the panel, the principle is very similar to the projector, so laser TV may not be a good choice for users who want to save space.
Brightness and viewing angle are not as good as LCD TVs
Compared with ordinary projection screens, it can be more effective against ambient light interference. Of course, no matter how good the projected display screen is, there is no way to achieve the effect of the LCD TV with its own backlight, and the influence of ambient light on it will be more obvious. Therefore, the problem of dimming the brightness of the laser television has not been effectively solved. In addition, in terms of viewing angle, because of the special reflective principle of the panel, the laser television cannot achieve an ultra-wide angle viewing angle like a liquid crystal television, and it will feel a significant drop in brightness after more than 120 degrees.
Laser TV screen brightness still needs technical breakthrough. Although the screen size is large, but the display effect is difficult to guarantee, so the brightness technology has become a basis for laser television to challenge the LCD. The brightness of current laser TVs is basically at 3,000 lumens, and the development of laser light source technology still requires a certain process from the industry's expectations.
Laser show the road to subversion
When lasers were just introduced, scientists discussed that if red, green, and blue lasers were used as the three primary colors to manufacture display devices, unprecedented color gamut coverage would inevitably be achieved, making large color gamut displays possible. The laser display can achieve all the advanced technical indicators that can be achieved by the traditional display, such as large screen, high resolution, digitization, etc., and the color gamut coverage can reach more than 90% of the color space recognized by human eyes, which is the traditional display gamut coverage. More than double the rate, thoroughly breaking through the first three generations of display technology
The deficiencies of the gamut space have enabled humanity to achieve the most perfect color reproduction in history, enabling people to see the most authentic and beautiful world through display terminals.
The 20th century primary cathode ray tube (CRT) brought the first display revolution; the flat display (FPD) brought a second display revolution, including flat display and projection display. Flat panel displays mainly include liquid crystal display (LCD), color plasma display (PDP), vacuum microelectronic display (FED), LED display (LED), ULED, OLED, QLED, and the like.
The flat panel display is mainly used for hanging televisions and large screen walls. The projection display includes a projection CRT, a projection LCD, and a laser projection technique (LDT). Laser full-color display is a leap-forward development of display technology. From the standpoint of industry product development, "first-generation television" refers to black and white television, "second-generation television" refers to color television, and "third-generation television" refers to high-definition television. TV, and "fourth generation TV" is laser television. 2016 was the exciting year for the color TV industry, and 2017 was the outbreak of laser television. “Big screen lasers” became the trend of choice for users. In terms of sales volume, laser television greatly surpassed the 8% growth rate of the LCD TV market. Laser TVs are also popular in the high-end business meeting rooms, especially the text ultra-high-definition display technology developed for business use scenarios, which solves many users' application problems.
The main application market for large-screen laser televisions is large-scale venues, such as Olympic stadiums, large conference rooms, hotel facilities, and municipal construction. Industrialization technology and the maturity of the market, the reduction of غير مجاز مي باشدt and price, the application rate of laser television in large venues will be greatly increased, and the time to enter the family will also be shortened. It is predicted that it will take 5 to 10 years for laser televisions to enter ordinary families. By then, laser televisions will replace traditional display televisions. If they enter homes, their annual output value will reach several hundred million yuan.
Laser TV industry chain analysis
China has nearly 90 color TV sets manufacturing companies, nearly 20 color tube production companies and hundreds of supporting parts and components companies, forming a complete industrial system integrating color TVs, color tubes, and components. Due to historical reasons, China's color TV companies engaged in the manufacture of downstream terminal products have difficulty in organizing a complete laser television technology chain and industrial chain.
Within the industry, relevant companies have not clearly positioned laser TV in a new round of strategic technology reserves, and it is difficult to abandon the existing scale of LED, OLED and other industries, resulting in technically advanced but lagged industrial enthusiasm. Chinese enterprises have always paid little attention to R&D, and they are accustomed to "taking in" a certain relationship. However, once the industrialization scale advantages are formed on laser televisions, the problems that restrict the development of the industry will be easily solved.
China has formed a semiconductor laser, all-solid-state laser, and a color laser display technology chain. At present, China is in sync with the international laser display technology, and has its own intellectual property rights. After missing the kinescope display and flat panel display, laser television may achieve a bend. Overtaking the “killer”, the localization and scale-up of semiconductor lasers are imminent. Although developed countries such as Germany, Japan, and the United States have all achieved success before China, it is difficult to ensure longevity, reliability, and غير مجاز مي باشدt reduction. Therefore, there has been no large-scale commercial use.
Outside the industry, the government also needs to treat laser television as a new technology product in the sunrise industry, giving more policy and financial support. Especially in the establishment of the laser display industry alliance, it also requires the government departments to make a match. China must turn its technological advantages in laser television into industrial advantages, and industrial integration and construction of standards are imperative.
In terms of research, many research institutes in China have researched and applied research and development and industrialized R&D capabilities in the laboratory of optoelectronic materials and devices. However, the overall level of China's optoelectronics industry has a large gap with international counterparts, and it is not efficient. The academic advantages are realized through engineering research and development and industrialization. There are few internationally competitive companies.
The laser television industry is a typical technology-intensive industry, which can drive leap-forward development in related key technology fields to form a new high-tech industrial cluster, and it may generate radiation amplification effects and achieve more significant economic benefits. Therefore, we should make the following adjustments to the decision-making and industry sectors. Grasping the opportunity of upgrading the international display industry, realizing the industrialization of laser television as soon as possible, and realizing the replacement of the display industry, it is imperative.
