These "stumbling block" is not the exception, Micro LED to mass production

With SONY a few years ago at Micro LED prototype TV after the 2016 CES exhibition and display updating technology Micro LED Micro LED TV, Apple also invested huge amounts of industrial transfer, and rumors of future Apple will import Micro LED in the mobile device on the display panel, so that the industry is looking forward to the Micro LED display technology, for LED backlight and LCD panel industry impact OLED panel growth has another feasible direction and options. Micro LED if you make the display panel like LED display, with dozens of inches to hundreds. This area is technically feasible, but also far from the commercial production, is the need for higher speed massive transfer of technology, put a small LED shift to the substrate, or using existing technology and good to create a rate available display, take too long to mass production. With LED spacing slightly, the traditional LED packaging cost in the whole LED display module in relative proportion, over the high, manufacturers can have miniature traditional LED the size of the wafer, but with package support, and hit the line, then do the cost and technology cannot balance the limitations. The future, if through the Micro-LED to display, do not need to package stent and metal wire, into a lower cost of traditional SMD-LED package. Micro LED production to solve the uniformity problem of Micro- LED products high wavelength uniformity, small spacing with LED wavelength uniformity is more demanding. The mass production of Blu ray LED wavelength uniformity under the standard requirements in the + 5~12nm, however small spacing display wavelength uniformity requirements, or even lower to 1-1.5 nm. If Micro is LED, the more stringent requirements. In other words, the scale of production, high precision transfer process to improve the process yield, at least to reach more than 99.9% levels, or even 99.999% such a better state. As a result, the industry needs to use the PCB board, but also to be able to complete the customization requirements, through the wire width / line from the development and drilling, by this ultra high density line, the only way to carrying huge Micro-LED pixels to consumers and users, the display can show high resolution and high quality the. In addition, the difficulty of Micro LED application in wisdom and wisdom bracelet watch, the LED driver development in IC is promising to complete, because of the need to control the pixel point less if it is used in the LED display with Micro LED, the IC will need to drive collocation highly customized, design method will drive circuit integration and scan, to simplify the PCB backplane design, improve the photoelectric conversion efficiency, because of high density pixel LED too much, resulting in insufficient space placement problem driven IC. At the same time, let the driving circuit to modular design, so that it can further save design and manufacturing cost. Micro LED industry development in the future, there are a lot of things or the industry gradually completed, to put a piece of the jigsaw.
