>> Micro LED cost less than 3% ultimate goal challenge AMOLED mobile phone panel 28th,July,2017
Micro LED is poised for the next generation, despite the industry for Micro LED application requirements and cost differences, but the industry estimates if Micro LED technology used in large-size indoor display, after the continued improvement in yield, Micro LED phase Compared to the existing small-footprint display cost will be 30 to 40% cheaper, as in the smart phone application market, Micro LED initial introduction of mobile phone costs are still high, but compared to the current flagship AMOLED models have the opportunity to reduce the spread to 3 to make.
Nissan Sony took the lead in displaying CLEDIS (Crystal LED Integrated Structure) display amazing industry, Sony 144 blocks seamless composition, the use of each size 403mm × 453mm RGB 3-color LED module, driven Micro LED into the high The new wave of commercial display. Sony CEO Chang Jingyi said CLEDIS major market will be replaced by a special size of the small pitch LED display, such as car exhibition hall, museum and other high-precision display purposes, Sony is expected to produce the second half of 2017.
Recently, ITRI and the accumulation of other manufacturers also invested Micro LED large-size high-end display application development, is expected to enter the production in 2018 is expected to enter production. LED manufacturers believe that, Micro LED have the opportunity to challenge the existing large-scale indoor display, the advantage is that Micro LED and small pitch display do not need backlight.
LED industry, pointed out that the LED as the main light-emitting materials, LED grain costs accounted for about half of the original LED must be packaged and other processes can be used in small-pitch display, if Micro LED under the control of yield, not only save the process , Material costs can also be significantly reduced.
According to the research organization CINNO estimates, LED grain size will be reduced from the existing 100μm or more to about 50μm, although Micro LED production early must overcome the yield bottleneck, but overall, the cost of material costs to simplify the cost competitiveness, The price can be reduced by about 30 to 40%.
Although the industry that Micro LED yield must be raised to 99.9999%, LED production dead pixels can be expected to drop to single digits, but ITRI that if the Micro LED composition of about 10cmx10cm module, its single Module LED number of about 10 to 200,000, through a special repair technology, will soon reach Micro LED into mass production possible.
As for the industry as the most difficult to import high-end smart phone applications, Micro LED has the opportunity to compete with the flexible AMOLED panel, the industry estimates Samsung Electronics (Samsung Electronics) flagship mobile phone panel costs about 70 US dollars, and 4-inch LED epitaxy After the grain cutting process, will be able to supply three 5-inch mobile phone demand, if accelerated to improve production and yield, the future Micro LED used in mobile phone panel costs about 90 to 100 US dollars, the initial spread can fall about 30 %, Will have the opportunity to struggle in the high-end market.
Micro LED has not yet officially entered mass production, the industry that the relevant cost estimates are still on paper stage, the future into mass production, OLED panel costs may have been rapidly reduced, however, Micro LED applications in the special niche market still has advantages, including Car, micro-projection, invisible light, and even for the recent biometric (such as fingerprint identification) used in full-screen mobile phone is difficult to identify the technical bottleneck, is also expected to be solved.
