According to insiders, the Institute of Electronics and Optoelectronics Systems Research Laboratory under the Industrial Technology Research Institute (EOSRL) has been working with PlayNitride, LED driver IC design company Macroblock and PCB manufacturer Unimicron Technology to develop ultra-small pitch Micro LED panels.
According to Macroblock sources, the first half of 2018 will be launched by the ultra-small pitch panels composed of large indoor commercial wall samples, the second half of the trial production.
Among them, Mcroblock is responsible for the development for Micro LED display Driver IC, PlayNitride is responsible for the development of sapphire substrate without the Micro LED wafer, and EOSRL is responsible for the development of a large number of Micro LED chip Related technology transferred to PCB developed by Unimicron.
PlayNitride has completed the development of a Micro LED wafer with RGB (red, green and blue) colors and is expected to complete the development of 2 LED RGB color micro-LED wafers by the end of 2017. At present, there are some Micro LED chips The huge amount of transfer, chip uniformity and PCBs absorption chip and other issues remain to be solved.
Accumulation technology has been developed specifically for Micro LED display Module driver IC MB15359 with a fine pixel pitch of 0.9375mm The company said the MB15395 can control 512 pixels with a minimum average drive current of 15μA (microampere) at low power and a 16-bit grayscale. In addition, the MB15395 It can also detect Micro LED chips that have or will fail during a mass transfer process, facilitating early repair and improving the display quality of Micro LED panels.
