BOE Display is one of the leading names in display technology. The company has built a reputation for itself in the aspect of LCD screens using its proprietary Advanced Super Dimension Switch (ADSDS) technology for liquid-crystal display (LCD) panels. The Chinese firm has also made some inroads into the aspect of OLED displays but still fall behind Samsung and LG when it comes to OLED panels. BOE has been striving to catch up with Samsung and has now included Micro LEDs to its product development.
Chinese tech blog IThomes quotes DigiTimes to have reported that BOE has started mass production of MicroLED panels in Kunming, Yunnan Province of China. The report states that mass production started in October this year and the company is looking for partners in MicroLED applications.

BOE had in May of this year demonstrated its innovative technology and solutions such as the 0.39-inch Micro-OLED AR with the highest 5644 PPI in the world at SID Display Week 2019. The microLED display was originally developed for use in telescopes, but BOE is now using it for AR/VR glasses, first-person view angle (FPV) goggles and projectors for drones.
MicroLED uses self-emission backlight just like OLED panels, unlike the traditional LCD displays which require LED backlight modules to emit light through layers from behind to generate images.
Micro LED can achieve effects such as very high contrast, extremely deep blacks, and fast response time just like OLED. However, Micro LED has higher brightness and is more stable than OLED because of its inorganic nature. In other words, red, green, and blue Micro LED pixels do not have luminance decay issues. Compared with that, each OLED pixel more or less suffers from luminance decay and the speed of decay varies. Despite these superior features, it may take a long time before microLED gains prominence over OLED. Samsung had deployed the technology on its The Wall TV but there have not been so many applications after that.
