Apple said to have chosen OLED for new iPhones; Japan Display shares plunge

Apple Inc has decided to use OLED screens in all three new iPhone models planned for next year, according to South Korea's Electronic Times - a report that sent shares in Japan Display tumbling 10 percent.

Japan Display, one of the main suppliers of iPhone liquid crystal display (LCD) screens, has lagged its South Korean rivals in OLED production. By contrast, shares in LG Display Co Ltd surged.

Apple recently started planning new iPhone models and decided all three models would have organic light-emitting diode panels, the report said on Monday, citing multiple unnamed industry sources.

A representative at Apple's South Korea office was not available for comment. A Japan Display spokesman declined to comment.

The stock was down 10 percent at the end of Tuesday's morning session, giving it a market value of about 105 billion yen ($965 million). At one stage it fell as much as 21 percent.

Cash-strapped Japan Display plans to start mass-producing OLED panels for smartphones only from 2019, and is looking for new investors who can finance investment to launch a production line.

"The Japanese government will continue to provide a lifeline to Japan Display, but the company has been just so slow in catching up with South Korean rivals in OLED," said Masayuki Otani, chief market analyst at Securities Japan.

It was formed in 2012 by combining the display businesses of Hitachi Ltd, Toshiba Corp and Sony Corp in a deal brokered by the state-backed Innovation Network Corp of Japan (INCJ).

Shares in LG Display gained 5 percent.

"If Apple uses OLED for all models for next year, that could raise hopes for LG Display to take a slice, as Apple may want to diversify its sources for OLED supply," said Lee Won-sik, an analyst at Shinyoung Securities in Seoul.
