Digitimes posted an interesting story, quoting PlayNitride's CEO that says that Micro-LED displays are easier to produce than people estimate. The company hopes to start mass producing such displays in the second half of 2017.
In PlayNitride's R&D setup, it takes about 10 seconds to transfer and place 200,000 LEDs - which means that a 5" panel will take only 10 minutes to produce. The yield rate at the company's setup is over 99%.
PlayNitride says that the cost of making a single smartphone panel could reach $300 - too expensive at this stage (although maybe not outrageously so, it is estimated that Apple's flexible OLEDs cost $120). Because of the high cost and high performance (efficiency, brightness and high PPI) PlayNitride aims to first enter the smartwatches, VR / AR, automotive and transparent display markets.
In April 2017 we posted that Samsung Display is set to acquire PlayNitride for around $150 million, but that deal did not materialize, it seems.
