China's LED display technology ranks among the world's first

Recently, the reporter learned from the Changchun Branch of the Chinese Academy of Sciences that Changchun Xida Electronic Technology Co., Ltd., a high-tech enterprise controlled by the Changchun Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences, which integrates scientific research, development, production, sales and postgraduate training, has undergone more than ten years of scientific and technological research. Recently, the world's first "dot array module full color LED super high uniformity display" was developed.

According to researcher Wang Ruiguang, the project leader, the core of the LED display 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. He applied for 12 patents, including 9 national invention patents. Mastering this technology marks that China's LED display technology has ranked among the world's first.

A typical LED display consists of hundreds of thousands or millions of semiconductor components (light emitting diodes). Due to the discrete nature of the components themselves, it is difficult to achieve high uniformity of the display by sorting these devices, and "the brightness and chromaticity point-by-point uniform correction technology for LED display screens suitable for mass production. "This is a good solution to this problem. At the same time, this technology also solves the problem of uneven brightness and chromaticity of the display caused by the attenuation of the LED.

"The dot matrix module full color LED super high uniformity display" also has a remarkable feature, that is, the lowest cost of raw materials, simple production process, stable quality, and the manufacturing cost is lower than the cost of the current "single lamp discrete LED display". %about. It is reported that the LED display of Changchun Xida Company is comparable to the products of Daktronics, Barco of Belgium and Lighthouse of the United Kingdom, both in terms of technical level and display effect, and the price has great advantages.

It is reported that this year, Hida will enter the Sino-Russian Science and Technology Park in Changchun. It is expected that the production capacity of the full-color LED ultra-high uniformity display of the dot matrix module in the second half of 2007 can be greatly improved.
