Flexible display, quantum dot (qled), laser display, micro led… With the deepening of a new round of scientific and technological revolution and industrial reform, China’s new display technology shows a trend of diversified development, and industrial opportunities and challenges coexist.
Some experts said that the new generation of display technology is developing rapidly. Among them, micro LED is a new generation of display technology, which has higher brightness, better luminous efficiency and lower power consumption than the existing OLED technology.
The reporter noted that many enterprises are continuing to strengthen forward-looking technology research and development and layout new display technologies such as micro led in advance.
Take Visionox Technology Inc(002387) as an example, Visionox Technology Inc(002387) joint-stock company Chengdu CHENXIAN optoelectronics Co., Ltd. recently announced the launch of a 12.7-inch micro led splicing display that can be used for high-end TV. The product has been independently developed and uses a 25 micron LED chip for the first time.
According to the relevant person in charge of vinos, the micro LED display adopts 6 pieces of splicing, and the seam is less than 100 microns. With the self-developed hybrid drive circuit architecture and high-speed massive transfer technology, CHENXIAN optoelectronics successfully achieved the display effect of 98% dci-p3 color gamut, 700nit brightness and 256 gray scale (8bit) color depth, and improved the transfer yield of 25 micron LED chip to 99.9%.
It is reported that CHENXIAN optoelectronics has built a micro LED display production line from driving backplane, massive transfer and repair to full coverage of modules. At present, in the field of micro led, CHENXIAN optoelectronics has 676 patent applications, accounting for 96.7% of invention patents.
For future development prospects, Hu Fei, senior researcher of CHENXIAN photoelectric technology planning department, revealed that in the field of glass based micro LED technology, CHENXIAN photoelectric will focus on high-end TV, vehicle and intelligent wearable applications, while silicon-based micro LED technology will focus on AR applications.
Visionox Technology Inc(002387) said that in the future, it will continue to adhere to the main business of AMOLED as the core, carry out innovation, expand cutting-edge display technology represented by micro led, and actively layout perceptual interaction technology.
