Although the actual production of Micro LED is still only in the stairs ring stage, but in the global market is huge, it is estimated that more than 100 teams have invested Micro LED research and development, the industry's more conservative estimates, Micro LED is expected to develop within 5 years Mature and optimistic industry is expected to begin trial production by the end of 2017, 2018 have the opportunity to use in the wearing device, but the industry revealed that even Apple (Apple) devoted a lot of resources, is still subject to Micro LED technology difficult to delay the progress, The future of Micro LED in the development of color, will become the battle of the battlefield battle.
Micro LED is seen as a star of tomorrow, although the technical bottleneck has not yet broken, but in the global technology giant led the investment, the market has not yet played a sensation, the relevant supply chain industry to break the head, want to squeeze into the rapid rise of Micro LED Train, then the face of a strong rise of the OLED camp, Micro LED fear will face full challenge, the industry that the development of color line, will determine the Micro LED contestants who can win.
At this stage Apple continued to increase the value of RGB three-color Micro LED research and development, but faced with yield, cost and other problems, making nearly a year Micro LED research and development progress is relatively slow, the industry speculated that with the three-color LED transfer to the substrate at the same time the difficulty of the recent The industry's trial products are mostly a single color, how to quickly break through the technical bottlenecks in the future, the development of cost-competitive full-color Micro LED, Micro LED will focus on whether the mainstream into the mainstream display.
Supply chain industry pointed out that the industry for full-color Micro LED has different attempts and challenges, the current highly anticipated is the full-color display production methods reduced to the Micro level, which will R, G, B three-color LED chip array and Shift, but the three-color LED current design is very different, color offset is the primary problem must be solved.
Another approach is to use a single blue LED chip, with a quantum dot material or special phosphor to achieve full color display, but the technical threshold facing the phosphor particles include a larger volume, can not meet the miniaturized LED chip size, and quantum Point of the material has a life problem, due to low heat and rapid failure, resulting in a large number of use, the industry initially estimated through the quantum dot material to achieve full color display, may only hundreds of hours of life.
From the progress of the process point of view, RGB three-color full-color program in the early stages of development is expected to quickly attract the attention of the industry, after all, in the trial production process, aside from mass production yield and cost considerations, as long as repeated to do the opportunity to make a show Models. As for the life of quantum dots if the problem can break through, there will be an opportunity to cf the OLED panel used in smart phones, and cost competitiveness will be the main advantage.
From the supply chain point of view, once the Micro LED through the RGB three colors to achieve full color display screen, this game will only be a small number of industry players can play, because the world can supply RGB three-color LED industry is limited, Electricity, Osram, etc .; but if the blue LED with quantum points, as long as the solution to the supply of quantum dots, other LED manufacturers have the opportunity to join the competition, and even evolved into a global expansion of the situation.
Looking back about 10 years ago, LED TV design line of the dispute, the early RGB LED three-color mixed light used in LED TV has led the coquettish, driven by the Japanese factory promising, but the RGB LED cost is too high, three-color brightness But also with the temperature rise showed varying degrees of attenuation, RGB direct type of high-end LED TV eventually only stay in a small number of flagship models.
As for the Korean-led Korean TV manufacturers, the use of side-light white LED backlight design, although the thickness of the fuselage has not been ultra-thin, can not be made directly under the regional control function, dynamic contrast and dynamic image quality upgrade It is not as straight down design, but the number of LED significantly reduced and simplified design, and with the traditional CCFL machine spreads narrowed significantly in the market sprang.
Supply chain industry believes that the competitiveness of emerging technologies mainly lies in the cost, and now OLED panel technology to promote the pace of fast, mainland and Japan may be in the OLED inkjet printing technology to lead, and even for the advantages of Korean factory to comeback, with the global panel The plant has been put into OLED production capacity, the cost reduction rate may be more than expected, and Micro LED in 3 to 5 years after what kind of competitive technology will be in the noise of the sudden come to an end, or all the way through the world Stage, the next 2 to 3 years of development will be the key.
