Previously, Samsung Electronics unit was the sole supplier of OLED screens for Apple. An LG Display spokesman declined to comment, while Apple representatives in South Korea were also not available for comment, Reuters reported. The South Korean newspaper quoted unidentified sources saying that the flexible LG OLED panel recently passed a series of Apple quality tests. If confirmed, the supply agreement with the US smartphone maker could help LG Display to get a place in the OLED display market, where the South Korean technology company has high hopes for the OLED business. LG’s mainstay, older-technology liquid crystal display (LCD) business is struggling with Chinese rivals and panel price declines.
