Japanese factory is not willing to show weakness and actively grab Micro LED display technology

AMOLED (active organic light-emitting diode) is popular because Apple will launch the OLED version, which is popular in the market. However, because the Korean manufacturer Samsung Display (SDC) dominates the global market of 95%, the Japanese factory will not be outdone to actively enter the Micro LED display. Technology, Apple also does not want Samsung to dominate, is developing Micro LED for small and medium-sized displays.

The Optoelectronics Association (PIDA) said that Micro LED is expected to become a panel market volatility. Micro-LEDs will be micro-level RGB three primary color LED chips on the substrate with high density, and a single chip will be used as a pixel to form a high-density matrix. It can effectively replace the CF and OLED luminescent materials of liquid crystal. Due to the excellent performance of LED lighting components in terms of stability and efficiency, and superior to OLED, coupled with the decline in chip prices and advances in technology development, Micro LED has developed a niche.

However, due to the current high technical threshold, although the Micro LED has advantages over OLED in terms of process and cost, the threshold of practical application technology is still quite high. PIDA pointed out that the blue-green LED chip is to galvanize GaN in sapphire. On the substrate, so the two can be fabricated at the same time, and the red LED chip is based on gallium arsenide, so integrating the RGB chip is not easy.

In order to achieve high image quality, the CLEDs manufactured by Sony, which has been manufactured by the company, use individual LED chips to make 2 million RGB chips and a total of 6 million LED chips for high-density packaging. The process is extremely difficult. If advanced to 4K/8K high resolution, in addition to high-density packaging technology, if a single chip is bad, it will affect the image effect.

PIDA estimates that Micro LED will have a chance to start commercial application at least until 2020. Although the technology is still difficult, the industry hopes to take advantage of Micro LED to regain market rights due to the loss of opportunities in the OLED technology competition.
