In January 2018 Sharp's CEO announced that Sharp aims to begin commercial production of flexible OLED displays for its own smartphones in Q1 2018. A new report from Taiwan says that Sharp is progressing with its OLED plans.
Digitimes now says that Sharp has converted some of its capacity at its 4.5-Gen Taki plant from LTPS LCDs to OLED displays. The Taki Plant had a total capacity of 90,000 monthly substrate, and a third of that capacity was converted to OLEDs (but rate will be slower for OLEDs - 22,000 monthly substrates). It is not clear whether Sharp actually started producing OLEDs already.
By the end of 2018, Sharp will convert all of this line's output to OLEDs. At Taki Sharp performs the front-end process (substrate + backplane) and the organic layers are deposited at Sharp's Sakai plant.
In October 2016 Sharp announced that it will invest $570 million and build OLED pilot lines at its plants in Osaka and in the Mie Prefecture, with plans to begin (pilot) production in the summer of 2018.
