Terminal display demand rising, the carrier can also display new, early from the TV for CRT display (CRT), to LCD, OLED has been gradually mature, although OLED has excellent performance, but with LED to improve the efficiency and progress of the manufacturing technology, Mini LED or Micro LED display business is also brewing in the.

LED pointed out that MicroLED is not a new concept, the industry there has been a long time, but on how to narrow the technology and handling? To overcome the problem in recent years with the manufacturing technology of LED plant is mature, significantly enhance the luminous efficiency of LED, application of Micro LED surfaced again, only Taiwan area manufacturers has cut out Mini LED as a relay station, and hope to achieve balance between technology and order income.

Mini LED is a term proposed by LED chip crystal power plant, on the crystal electric internal definition, Mini LED refers to the chip size of about 100 microns LED, while Micro LED refers to the 50 micron below LED, from the production point of view, Mini LED epitaxy, chip technology is feasible, crystal only need to invest small amounts of electrical equipment can be mass production; although no problem too big in front end process on Micro LED, but the existence of wafer handling bottleneck, enough to make the cost climb, become the biggest fatal commercial applications, crystal power estimation, the real distance about 3 years to mass production.

EPISTAR have estimated that the expansion of a new Micro LED factory about 20 billion yuan (NT, the same below), from the factory to cover production for about 2 years, if only in a small size wearable device, a monthly revenue of only 20 million yuan, the investment rate of return to crystal electric abacus type, so the crystal electric speech the pipeline never really accepted with the United States Department of manufacturers to cooperate in the development of Micro LED.

From the application point of view, museums, cinema has been planning the introduction of Mini LED, South Korea's going to the cinema next year; another application is the use of Mini LED to replace the LCD TV direct type backlight, crystal electric analysis, using Mini LED as the backlight has better color rendering, can be Local Dimming also, the thickness of reaching OLED, saving up to 80%, and even the mainland mobile phone industry began to Mini LED as the backlight source, use the number as high as 9000, crystal electric expected in next year's CES exhibition, you can see a lot of design Mini LED as backlight source.
