The latest Apple smart watch is equipped with micro led small screen market, and the OLED

when BOE's anti-corrosion performance goes offline to produce domestic flexible OLED screens, the whole industry is excited about it. After all, OLED is the future development direction of the display screen, which has been agreed by almost all manufacturers. Whether mobile devices or large display devices, OLED may be used as a more advantageous screen in the future

however, in the smaller screen display, some different changes have taken place. As we all know, the apple watch launched by Apple was already the third largest wearable device in the world in terms of shipments in Q2 this year, second only to Xiaomi and Fitbit. The apple watch uses AMOLED screen, which has been loved by users since the product was born

What are the advantages of micro led over OLED?

according to the latest news, Apple will invest the display technology of the new generation of products in micro led, which has aroused thousands of waves with one stone. Immediately, the topic of micro led against OLED is also rampant

micro LED display adopts micron led size, which can independently control pixels and emit light independently. It has the characteristics of high brightness, low power consumption, ultra-high resolution and high color intensity. If combined with nano wiring, even ultra small LED can achieve the characteristics of flexible screen

compared with OLED, micro LED has similar high color saturation, can self emit light, and the power consumption is only one tenth of it. Therefore, apple crossbeam moves up and down under the control of hydraulic cylinder to complete the loading of the experiment. Both snoy and micro LED display panel hope to adopt micro LED display panel as the display of portable products in 2018. For this reason, apple acquired luxvue, which mainly develops micro LED display technology, in 2014

although Apple's latest iPhone x uses a Samsung OLED display, it is clear that it is also making two preparations. At present, micro led design schemes are divided into full-color RGB mixed light or white light. The former can achieve 100% NTSC high color gamut display, while the white micro led through blue LED and phosphor can achieve 80~90% NTSC display effect. It is expected that terminal products will appear at CES 2018

micro LED industry status and bottleneck analysis

due to efforts to achieve the best balance between economic benefits, environmental benefits and social benefits, the current LED backlight and small spacing display screen market competition is fierce, so the major LED manufacturers are having a hard time. However, AMOLED screen manufacturers are still relatively rare, so many LED manufacturers have turned their attention to the emerging battlefield of micro led

according to relevant research reports, the current size of XY test bench: 100 × The biggest bottleneck in the mass production of 100mmmmicro LED displays lies in how to transfer a large number of micron sizes to the circuit substrate, that is, mass transfer. Although the huge advantages of micro led have attracted the attention of major display manufacturers, semiconductor manufacturers and LED manufacturers around the world, for the bottleneck in the mass production of micro led, all manufacturers are stepping up the development of breakthrough technologies, hoping to win the market

in this report, the size of micro LED chip is defined as 100 μ M or less, but at present, the mainstream size of micro led development in the industry is still 150 μ m. The development of massive transfer technology is also based on 150 μ M as the target, so it is believed that the LED size of the leading generation of micro LED displays and projector modules in the market will fall below 150 μ m。 As for 100 μ M-Size displays will have to wait for further development by competitors

the prospect is bright, and many manufacturers flock to it.

at present, in Taiwan, China, many display manufacturers will not miss micro led, a screen technology that can compete with OLED in the future, including crystal optoelectronics, Youda optoelectronics and qunchuang optoelectronics, which have actively invested in the research and development of micro LED display related technologies. Globally, Samsung, LG, Nichia chemical, sharp, Sony and luxvue, which was acquired by apple, are all working on the development of micro led

as for Chinese Mainland, San'an optoelectronics said recently that micro LED is the key development direction of its company in the future, and it has started research and development as early as oneortwo years ago. Last year, Riad also launched ultra micro p0.9 mm HD seamless wall splicing, which is the leading LED display with a spacing of less than 1 mm to achieve mass production in the market. But generally speaking, the Chinese Mainland market pays more attention to the LED commercial market, and the investment in micro led, a cutting-edge technology, is still small

the advanced mass production of BOE's 6th generation flexible AMOLED production line has become a representative event in the domestic panel industry, which once again proves to the world the strong technical strength of Chinese enterprises and is expected to break Samsung's long-term monopoly in this field

however, in the field of small-size display panels, micro LED technology is also gradually maturing. If Apple uses micro LED display panel as promised, it will have a great impact on OLED. Various signs also show that in order to get rid of the constraints of Samsung and other companies, Apple's enthusiasm for micro LED technology will be very high

in the field of new display, new technologies continue to emerge. At present, China has achieved large-scale layout in OLED panels, and the main work in the future is to improve production capacity and yield, while micro LED technology needs to be strengthened
