The lab announced the formation of the Consortium for Intelligent Micro-assembly System, integrating quantum dot material suppliers, IC design houses and LED makers to jointly develop such panels.
EOSRL, under the Taiwan government-sponsored Industrial Technology Research Institute (ITRI), is now capable of mass-transferring 2,500 (50x50) micro LED chips on an area of 100x100mm at a yield rate of 99.9%, reports Digitimes. The lab is looking to increase these mass transfers to 10,000 (100x100) micro LED chips by the end of 2017 or the beginning of 2018.
With micro LED chips 5-micrometer in size, these monochrome micro LED panels are made at a resolution of QHD (960x540). By the end of 2018, EOSRL aims to reach a resolution of 4K2K with a pixel density of 1,000ppi for monochrome micro LED panels, targeting 8K4K and 2,500ppi by 2019.
Another application of such Micro LED panels could be to make ultra-fine pixel pitch indoor displays. Although micro LEDs are not yet cost competitive with OLEDs for smartphone displays, ironing out transfer processes and yield could make them a good candidate, as their production lines are much less expensive to set up than OLED lines. EOSRL announced it will set up a trial production line for micro LED panels.
