The key technologies of China's LED high-end display new progress has been mastered

High-end led China's big screen core technology has made a major breakthrough, break the foreign technology blockade on the display field of our country and the monopoly in the high-end large screen LED, key indicators have reached international advanced level. The Chinese Academy of Sciences Institute of Optics and Changchun Changchun Hilda Electronics Technology Co. Ltd. joint research, breakthrough LED large screen display in point light color parameters acquisition, brightness and chroma factory and field calibration and display control, high precision control, the gray detection technology assessment and industrial production, the bottleneck of LED large screen display in the uniform definition and, the color deviation correction and gray control, data transmission, image processing, high refresh rate and high resolution technology among the world's advanced level.

Through the implementation of the project undertaker, also developed a special LED color parameter acquisition instrument, LED special comprehensive evaluation platform, establish the LED large screen display system of quality assessment, significantly enhance the capability of independent innovation of China's LED display; apply for core 40 patents, published nearly 20. The paper has at the National Theatre "revival", the main display shows the oval 60 anniversary of national day wonderful Jilin national day, Shanghai the Bund "float shaped display cubic phantom" and Shanghai landmark "Jinmao Tower" outdoor display engineering application of the project in the major display.

The implementation and application of this subject, the ability to raise the level of industrialization of China's high-end LED large screen display and participate in the international competition, the establishment and improvement of LED technology and testing standards, testing methods and evaluation platform support system, promoting China's LED display industry sustainable development and lay a solid foundation for industrialization and strong technical support
