Nationstar Optoelectronics successfully launched the 1.84-inch full-color Micro LED display nStar III, ushering in a brilliant achievement

According to news from this website on December 6, recently, Nationstar’s Micro LED ultra-high-definition display research and development project has reached a milestone. Successfully lit up a 1.84-inch Micro LED full-color display - nStar Ⅲ .

According to the official introduction, the screen uses an LTPS-TFT glass-based driver backplane, with a pixel pitch reduced to 0.078mm and a resolution of 360 *480, using a fully flip-chip substrate-less LED pixel light-emitting unit, can achieve a peak screen brightness of >1500nits, and related technological achievements are expected to be widely used in smart wearable products such as Micro LED watches in the future.

This screen adopts the mass transfer technology route independently developed by Nationstar Optoelectronics to achieve high-density integration of more than 500,000 Micro LED chips. The placement accuracy of R/G/B three-color chips is less than 2um, and the transfer is excellent. Rate＞99.9%. In addition, Nationstar’s Micro LED R&D platform can also support multiple splicing and bonding of chips on substrates within 12 inches in the future.

So far, Nationstar Optoelectronics has realized the "Future Nationstar Screen" matrix for diversified scenarios with pixel pitches ranging from P0.X to P0.0X. Nationstar Optoelectronics said that next, the company will continue to delve into the Micro LED micro-display track, develop silicon-based AR display technology, and create a more comprehensive and diversified layout of Micro LED application fields.

This site learned from the official website of Nationstar Optoelectronics that Foshan Nationstar Optoelectronics Co., Ltd. ("Nationstar Optoelectronics" for short) was established in 1969 with a registered capital of 620 million yuan. It is a key state-owned enterprise in Guangdong Province Guangsheng Holding Group's holding listed company specializes in R&D, production, and sales of LEDs and LED application products. is the first company in China to be listed on the market with LED as its main business, and is also one of the earliest companies to produce LEDs.
