PlayNitride raises $50 million, will start trial production of microLED chips by the end of August 2019

Digitimes reports that PlayNitride raised $50 million and is ready to start trial production of micro-LED chips by the end of August 2019. PlayNitride will increase its headcount by 100 employees.

PlayNitride told Digitimes that it achieved a yield rate of 99.9% in its LED transfer (pick-and-place) process. Using mass repair technologies, the company is certain it can achieve commercial viability of its process. The company's mass transfer speed is 10,000 chips per second. This means that for a Full-HD (1920x1080) display it will take just over 10 minutes to transfer the LED chips. A 4K display will take just over 40 minutes.

Coherent reports new orders for its Micro-LED laser R&D tools

Laser equipment maker Coherent says that its customer have expressed a "reasonable amount of interest " in its Micro-LED solutions. The company is taking orders for R&D tools, but it says that mass production of Micro-LED displays is "still years away".

Coherent offers several laser-based tools used to produce Micro-LED displays, including Laser Lift-Off equipment (LLO) used to separate micro-LEDs from the sapphire wafer and Laser Induced Forward Transfer (LIFT) used to move micro-LEDs from the donor to substrate.
