LG Display has announced that it is in mass production with the world's first circular plastic OLED screen. This little screen measures 1.3-inches in diameter and is the circular screen from the LG G Watch R that debuted late last month. This thin display will eventually turn up as the screen for other wearables on the smartwatch market.
While the round screen certainly looks good and makes smartwatches using it look more like a traditional watch, the main reason for the round screen is to get more viewable space in the same footprint. The round screen has a 57% larger viewing area than a square screen of the same size.
Resolution for the 1.3-inch circular screen is 320 x 320 and it has 100% color gamut, 300-nit peak luminance, and unlimited contrast ratio. One of the best features of the display for wearables is that it has the ability to use Power Save Mode so the screen can stay on at full resolution without power from the integrated circuit.
That means that wearables using the display will have longer battery life than others with screens lacking power save mode technology. LG Display is using new techniques to mass produce this circular screen with new processes to improve deposition efficiency and a highly precise laser cutting and processing technology is employed.
