Introduction: The Changchun Institute of Optics and Physics of the Chinese Academy of Sciences Changchun Xida Electronic Technology Co., Ltd. has developed the world's first dot matrix module full-color LED ultra-high uniformity display screen after more than ten years of scientific and technological research. According to researcher Wang Ruiguang, the person in charge of the development, the core technology of the LED display screen is “the brightness and color point-by-point uniform correction technology for LED display screens suitable for large-scale mass production†with complete independent intellectual property rights. It has applied for 12 patents, including 9 national invention patents, which indicates that China's LED display has ranked among the world's first. Usually, the LED display is composed of hundreds of thousands or millions of semiconductor components (light-emitting diodes). Due to the discreteness of the components themselves, it is difficult to achieve high uniformity of the display. "LED full-color large-screen display", using brightness and color compensation technology, completely solves the problem of uniformity of the display screen, realizes the brightness of the basic color of the illumination can be independently adjusted, eliminates various color deviations during display, and ensures the color of the whole screen. Brightness uniformity and consistency; using high-precision display grayscale control technology, the display has 4 trillion color performance capabilities, can reproduce 16 million colors nonlinearly, make the image layer more delicate, and the color transition is softer The image is more realistic; use the industry-leading control system to ensure the best image quality for the display. "The dot matrix module full-color LED ultra-high uniformity display" also has a remarkable feature, that is, the lowest cost of raw materials, simple production process, stable quality, and the production cost is lower than the current "single-lamp discrete LED display". About 20%.
