Apple will use OLED panels by LG Display for some versions of the new iPhone 12 set for release in September this year.
Until now, Apple has mostly used OLED panels from rival Samsung Display.
Industry sources on Tuesday said LG Display will supply the panels for the 6.1-inch iPhone 12 Max. LG Display declined to comment, but the company has already prepared its OLED manufacturing plant in Paju for full production.
LG Display suffered six straight quarters of losses due to weak LCD market conditions and is betting everything on OLED panels.
OLED is expected to replace LCD on most smartphones in the future. It emits its own light and is clearer and thinner than LCD and can even be bent.
