Energy-saving and environmental protection, high-definition, high brightness, easy operation and many other advantages of LED display, these years have been rapid development. The market demand for full-color LED displays has rapidly increased, and the scale of application has become wider and wider. Gradually from the wild advertising media, to the stage rental, to the hotel, conference rooms, stadiums, field traffic guidance and so on.
LED display so hot, what is the reason behind the LED electronic display can quickly replace the traditional advertising preface in a few years, and become the new carrier of today's outdoor advertising media? In fact, the reason for ending is still because the full-color display has the unparalleled advantage of other traditional advertising prefaces.
I. From the perspective of commercial advertising: LED display strives to achieve the highest performance quote
Full-color LED displays have been launched today, offer prices gradually reduced, and more and more sophisticated skills and quality. The longevity of LED display is used, which is equivalent to the highest غير مجاز مي باشدt performance of the display. Other displays have a very eye-catching feature.
Business operations are economically sensible. As advertising media, they must be able to attract the attention of the audience and be recognized by advertisers. In a word, it is necessary for LED display manufacturers, advertising operators, and advertisers to benefit from it. Among the various advertising media, the advantages of full-color LED displays are its rapid changes, diversified screens, and dazzling display. The following five points are the most important features of the detailed features:
1. Brightness: Under the conditions of direct sunlight in the field, the brightness of 5000CD is required. It is enough for the room to be around 1000cd. There is also a half-time in-between center. Brightness automation is getting more and more popular with many customers.
Lifetime refers to the moment when the system is unable to recover to a regular skill indicator. It is related to reliability, but it is not the same concept. The longevity of a large screen depends primarily on the lifetime of the luminous tube. The lifetime of the luminous tube refers to the time when the light intensity of the luminous tube decreases to half of the nominal value. The longevity number of light emitting tubes is as high as that of high-end electronic products in electronic devices. The attenuation of luminous intensity of the luminous tube is greatly related to the quality of the tube, operating current and operating environment. Even if it is a long-lived brand-name tube, if the operating conditions are not appropriate, the number of lives will be shortened. These are related to the غير مجاز مي باشدt. The fact that almost all manufacturers regard the lifetime of LED as the life of a large screen is actually wrong. The longevity of the big screen should eventually be a question of the performance quote ratio. Accounting investment and return for accounting business operations have the best share. In most cases, the demand for 100,000 hours of life is not only unrealistic but also unnecessary.
3. Function: The intention of the advertisement is to publicize, attract eyeballs, and establish an in-depth image for the audience. The picture is delicate and important. After various ideas, changes and other techniques can receive a good effect. The change of the neon light is very limited. The led display has more forms than the neon light, which is enough for advertising purposes. The large screen is divided into two types: synchronous screen and asynchronous screen. The synchronization screen is like the monitor of the auditing machine. It has many changes and full functions. It requires a machine and communication to work all the time. The asynchronous screen is controlled by a single-chip microcomputer or an embedded system. The displayed contents are written once and stopped until the next update. Advanced handlers can perform grayscale and video functions in the same way. Asynchronous screens are more suitable for slower advertising and information changes in many situations.
The simple MCU or small embedded system has low disposal ability and lower gray level and speed of rewriting. However, there are still talents to meet the various changes in texts, animations, and pictures.
4. Resolution: The resolution or resolution depends on the pixel density. In the display screen, the غير مجاز مي باشدt of pixels accounts for more than half. Therefore, reducing pixel غير مجاز مي باشدts is the most attractive, pixel separation skills or dynamic pixel skills is a common method. Dynamic pixel technology is not a new skill, and it has been used for at least ten years. It has achieved a number of times improvement in visual resolution through the method of pixel sharing.
5. Other skill indicators, such as the broadcast method, gray level, rewriting frequency and dynamic size, etc.: Data Bandwidth The screen for commercial advertising should be selected from the perspective of the performance quotation ratio, and it is not much to say here. Some people divide the big screen into four levels: broadcast, professional, multimedia, and simple. It is comparatively scientific in terms of function and video. It is necessary to select the best screen that is most suitable for use based on the practical application requirements and funding levels. Image engineering is broadcast or professional, commercial advertising is mainly multimedia, and simple text and graphics can be used in simple levels.
Second, from the visual engineering point of view: aiming at world-class level
Image engineering means that the primary purpose of creating a full-color LED display in Guangzhou is to increase the appearance of a city or a serious event. It does not directly invent economic benefits, but it can promote city awareness, portray city image, improve investment environment, and build business. The air is conducive to economic development, has outstanding social benefits, and then indirectly invents economic benefits. The image project is mainly funded by the government, focusing on social benefits, rather than or not primarily through commercial operations to obtain economic benefits. In recent years, LED large screens in large-scale urban squares or citizens' leisure squares created in many parts of the country are typical image projects. A lot of stadium led display screens are the necessary supporting equipment for modern sports venues. They also belong to this category.
