LED Display, New Technology Always Brings New Challenges And Inspires New Imagitnaion.
The voice of LED display technology has entered the cinema line. Because the traditional projection system has its weaknesses: LED display in the film market advantage, big screen Jun feel not only brightness; LED screen in the film market development, can not only rely on brightness indicators. First of all, the LED screen can also be used for low brightness. The principle is simple: smaller LED crystal particles, such as 50 micron products, can achieve a significant reduction in brightness without changing the color and contrast indicators --- that is, the black room mode of LED film projection system is not a technical problem.
Second, the LED screen can also be a low-cost product. For example, the point spacing of 10m giant screen application 4K is close to 2.5mm - this indicator is very low for LED screen integration process. If the market demand is huge, the unit price of such products can be measured at 10,000 yuan, or even lower. Third, LED shows that it can be used for movie projection to meet the "super high resolution". For example, at present, small spacing LED screen, 1 spacing products have been put into operation. Such a level of technology can achieve a 20-kilometer high resolution on a 20-meter screen - of course, the screen Jun to point out that such a high resolution, what can be used to play, or a need for careful study. Perhaps movie screenings will never reach the limit of the LED screen. Fourth, the application of LED screen in the movie market should make full use of the latest technology of LED industry. It includes mini-led, COB packaging, flip chip, CSP wafer-level packaging, trichromatic eutectic technology, and new semiconductor doping materials such as perovskite, etc. The continuous application of these technologies will inevitably provide continuous "creativity" and competitiveness for LED screens in the film projection market. Of course, as the traditional ruler of the film projection market, digital film projectors are not "idle". Dapingjun understands that since 2017, RGB laser light source technology has been popularized and hundreds of products have been installed in the global market. At the same time, 8K products have been put on the agenda and are expected to become the standard of the next generation of giant screen cinemas. The application of 6-film projectors also helps to solve the problem of insufficient brightness of 3D applications in the film projection process. Question.
