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

Micro LED is optimistic about the perfect application of a new generation of display technology, although the international manufacturer of sound on the table is not much, in fact, has long been a duck water technology layout. According to the latest research report, wearable devices and indoor display is expected to be the fastest introduction of Micro LED applications. If the wearable device and indoor display all replaced by a Micro LED display, the required capacity will be 50% of the existing global LED capacity. Zhang Jiahong said that in the past, the new development of the display technology is to start training from small size, to overcome the yield and cost of production, and then move to large size. However, the choice of Micro LED entry point is the two extremes, one side is the smallest size wrist watch, while the other is the size of a large public display. Zhang Jiahong pointed out that, due to the Micro LED technology will be pixels and light source to do so, so Micro LED development roadmap and specifications, and the display pixel size, the number of 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 introduction of large scale Micro LED application part, the advantage is PPI (pixel density) is low, Micro LED can not be too small, the disadvantage is that the number is too much, you need to wait for a 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 China 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 acquisition of LuxVue and spin off from the University of Illinois, X-celeprint Micro LED transfer (Transfer) technology in front of other manufacturers.
