CRT), to the already mature LCD, OLED, despite the excellent OLED performance, but with the LED efficiency, manufacturing technology, but also to improve the efficiency of the LED, Progress, Mini LED or Micro LED display business opportunities are also brewing.
Taiwan LED factory pointed out that, Micro LED is not a new concept, there is a long industry, but technically how to narrow it and handling? Is the problem to be overcome in recent years with the LED factory manufacturing technology is mature, LED luminous efficiency increased significantly, Micro LED application again floated on the table, but Taiwan manufacturers and cut out the Mini LED as a relay station, hope in technology and Order income to achieve a balance point.
Mini LED is the word by the Taiwan LED chip factory crystal proposed, the crystal within the definition of the internal, Mini LED refers to the chip size of about 100 micron LED, and Micro LED is generally referred to as 50 microns below the LED, from the production Point of view, Mini LED in the epitaxy, the chip technology has been feasible, crystal power only need to invest a small amount of equipment can be mass production; As the Micro LED in the previous process, although no big problem, the chip handling is bottleneck , Enough to make high cost, become the biggest fatal injury business applications, crystal power estimates, from the real mass production about 3 years.
Crystal has estimated that the expansion of a new Micro LED factory about 20 billion yuan (NT, the same below), from the cover to the production of about 2 years, if only in the application of small size wear device, a month of revenue only 2 10 million, this investment rate of return to the crystal abacus re-hit, so crystal power pipeline has never really recognized with the US Department of manufacturers to develop Micro LED.
From the application point of view, museums, cinemas have been planning to introduce Mini LED, South Korea's cinema intended to be used next year; another application is the use of Mini LED LCD TV to replace the direct backlight, crystal analysis, the use of Mini LED For the backlight has a better color rendering, can do Local Dimming, thickness also approaches OLED, saving up to 80%, and even the mainland mobile phone industry began to Mini LED as a backlight, the use of up to 9,000 Electric expectations, next year's CES show, you can see a large number of Mini LED as a backlight design.
