Micro LED commercial or consumption of existing global production capacity of 50% LED!

Micro LED is optimistic about the perfect application of a new generation of display technology, although the international manufacturers on the table is not much sound, in fact, already ducks water skiing technical layout. According to the latest research report, "wearable devices" and "indoor display" is expected to be the fastest to import Micro LED applications. If the wearable device and the indoor display screen are all replaced by the Micro LED display, the required capacity will be 50% of the world's existing LED capacity. Zhang Jiahong said that in the past, the new development of display technology is mostly started from small size training, to overcome the manufacturing yield and cost, and then move to a large size. However, the entry point for the Micro LED selection is two extremes, one with the smallest watch bracelet and one with a large public display. Zhang Jiahong pointed out that, because Micro LED technology will "pixel" and "light source" combination, so Micro LED development route and specifications, with the display pixel size, quantity closely linked. In a small size, less the pixel itself has the advantage, and the size of the wearable device than the two inch wafer is small, MicroLED can also transfer by wafer bonding (Waferbonding) process will be further simplified, reducing the threshold. In the Micro LED import large size of the application part, its advantage is PPI (pixel density) low, Micro LED can not use too small, and the disadvantage is that the amount is too much, you need to wait for more mature transfer technology. Zhang Jiahong said that if the screen stitching mode, can directly solve the production problems of large size, taking into account the production conditions reduce the number of LED and enlarge the size, so in theory than the wearable device earlier into the practical stage. At this stage, Taiwan Chinese dedicated Micro LED developed a crystal power, neptunium (PlayNitride), a Taiwan Research Institute (ITRI), AUO and Innolux, a complete supply chain is the best development advantages of Taiwan factory; Samsung, LG, SHARP, Nichia, SONY and other international manufacturers did not miss. Apple's LuxVue and X-celeprint, a spin off from the University of Illinois, are ahead of other vendors in Micro LED transfer (Transfer) process technology.
