A relatively late entrant to the OLED market, Japan Display missed out on orders from its main client, Apple last year and as a lot of you know, the iPhone XS and iPhone XS Max sport OLED displays. However, if a new report is to go by, the two have struck a deal again. Apparently, Japan Display would be supplying OLED displays for the Apple Watch Series 5.

According to two sources privy to the matter, this would be the first time the Japanese company manufactures OLED for a company, as previously it’s operations were focused on LCD screens. Apple accounted for more than 50 percent of the sales of Japan Display and since the Cupertino giant is now more inclined towards OLEDs, the display maker suffered heavily.
