LG Display Starts Mass Production of World's First Circular Plastic OLED Display

Introduced with the LG G Watch R, the perfectly round and ultra slim display will bring design innovations to wearable devices

Seoul, Korea (Sept. 4, 2014) - LG Display, the world's leading innovator of display technologies, announced today that it has started mass production of the world's first circular Plastic OLED (P-OLED) display. The cutting-edge display will be used for the LG G Watch R to be showcased at IFA 2014 in Berlin, opening a new era of wearable devices by bringing innovative and stylish designs to such devices.


With a 1.3-inch diameter, the new innovative display is perfectly round and allows the LG G Watch R to have a full watch face, while promoting ease of use since the screen area is 57 percent larger than that of a square display of the same size. The world's first P-OLED panel has an ultra slim thinness of less than 0.6mm, optimized for wearable devices. With 320X320 resolution, LG Display's breakthrough display realizes 100 percent color gamut, 300nit peak luminance, and unlimited contrast ratio to enhance user satisfaction.

LG Display aims to realize the original intentions of wearable devices by enabling the screen to be turned on at all times while using the least amount of power with the Power Save Mode (PSM), which enables the screen to retain the same resolution--even without a power supply--from the power integrated circuit.

LG Display was able to achieve the world's first mass production of circular P-OLED displays by developing a circular mask that enables organic materials to be deposited simultaneously and a new production process that improves deposition efficiency while employing a highly precise laser cutting and processing technology.

"This first circular P-OLED display is yet another breakthrough that proves LG Display is ahead in OLED and the next-generation display technologies," said Sang-Deog Yeo, Executive Vice President and Chief Technology Officer at LG Display. He added, "We will respond to the fast-growing wearable devices market by continuously developing innovative technologies to meet the needs and demands of various customers, thereby leading the market."
