Micro LED market is promising

Although there is still some distance the distance from the commercial production,  the optimistic view on the future of Micro LED still attracts domestic and foreign manufacturers competing bet. According to the statistics of photoelectric Association, Taiwan, the United States, Japan, France, Ireland and other countries have company who invested Micro LED development. In addition to front-line manufacturers Apple, Sony, according to the data of Photoelectric Association, a panel industry origin Chen Liyi founder Mikro Mesa, has begun to apply for Micro LED related patents, and set up development laboratory in Chongqing, Sichuan.

LED as a light-emitting components, in addition to excellent function and stability, chip prices rapidly decline and technological development proceeds in recent years, has gradually become practical application on the product, but the technical threshold is still quite high.

Blu-ray and green LED chip is gallium nitride (GaN) epitaxy on the sapphire substrate. Red LED chip is gallium arsenide (GaAs) as the substrate, integrating with RGB chip is not easy.

He took Sony's CLED as an example, in order to achieve high-quality (Full HD) effect, the use of individual manufacturing LED chip, the 2 million group of RGB chips, in a total of 6 million LED chips for high-density packaging, which is a difficult process. Advanced to 4K / 8K, in addition to high-density packaging technology, if a single chip in bad situation, you can expect to show the results. Therefore, the probability that Micro LED focus on small and medium-sized panel is high currently.
