Samsung (SSNLF.PK, SSNGY.OB), by far Universal Display's (OLED +3.7%) largest customer, says it has begun mass-producing a 5.7" 1080p flexible OLED panel, and soon plans to launch a phone that makes use of them. A variant of the Galaxy Note 3 (has a 5.7" 1080p display) is a good possibility.
OLED-Info.com estimates the manufacturing line being used by Samsung can produce a few hundred thousand flexible 5.7" panels per month.
Meanwhile, LG Display (LPL -0.9%) says it will start mass-production of a 6" curved OLED, while deeming it "the world’s first flexible OLED panel for smartphones." A source tells Reuters LG Electronics (LGEIY.OB) will use the panels to launch an expected curved display phone next month.
