Micro LED commercially or consumes 50% of the world's existing LED capacity.

Micro LED is expected to be the perfect application of the new generation of display technology. In spite of the low voice on the table, the international factory has already made the technical layout of the duck water skiing. According to the latest research report, "wearable devices" and "indoor display" are expected to be the fastest importing Micro LED applications. If the wearable device and the indoor display screen are completely replaced by the Micro LED display, the capacity will be 50% of the world's existing LED capacity. Zhang Jiahong said that the previous development of the display technology is first to start from small size, to overcome the production rate and cost, and then move to large size. The Micro LED choice, however, is the two extremes on one side, with the smallest size watch ring on one side and a large public display on one side. Zhang Jiahong pointed out that because Micro LED technology combines "pixel" with "light source", the development route and specification of Micro LED is closely related to the size and quantity of the display pixel. In small size, it has the advantage of small pixels, and the size of the wearable device is smaller than two inch wafer. When the MicroLED is transferred, the wafer bonding (Waferbonding) can be used to further simplify the process and reduce the technical threshold. Micro LED import large size application part, its advantage is PPI (pixel density) low, Micro LED can not be too small, the disadvantage is too much quantity, need to wait for more mature transfer technology. According to Zhang Jiahong, if the display mode is used, the large scale production problem can be solved directly. At the same time, the quantity and size of LED can be reduced. Therefore, it can theoretically go into the practical stage earlier than the wearable device. At the present stage, Taiwan is devoted to the Micro LED research and development of crystal electricity, PlayNitride, ITRI, friendship and group creation. The complete supply chain is the best development advantage of the plant; Samsung, LG, Japan Asia chemistry, SHARP, SONY and other major international plants are also absent. And Apple's LuxVue and X-celeprint, separated from the University of Illinois, lead other vendors in the Micro LED transfer (Transfer) process technology.
