Chinese OLED developer Royole announced that it will establish a 16 billion yuan ($2.4 billion USD) OLED production line in Qingdao, China.

Royole did not provide any details, besides that this production line will be used to make flexible and foldable OLEDs. We do not know yet the timeline, technologies and production capacity at the new line.

Seiko Epson announced that it has developed its fourth generation optical engines for smart glasses, which will be used in the company's future Moverio series - and will also be offered to customers in the consumer and industrial smart glasses markets.

The new optical engine boasts 1.5X greater density, 5X greater contrast, and a 1.5X wider field of view than Epson's previous optical engines. Epson has developed a new OLED microdisplay (branded as Si-OLED) that is 0.453-inch in size with a resolution of 1920x1080 and a contrast ratio of 500,000:1.
