LG Display has announced 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.

With a 1.3-inch diameter, the 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% larger than that of a square display of the same size, said LG. The P-OLED panel has an ultra slim thinness of less than 0.6mm, 320 by 320 resolution, 100% color gamut, 300nit peak luminance, and unlimited contrast ratio to enhance user satisfaction.

LG said it 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 added it was able to achieve 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.
