Until this year, the largest OLED panel that electronics manufacturers could mass-produce was 31 inches—four inches smaller than the average TV in U.S. homes. In January, LG debuted the 55-inch OLED 3-D Cinema Smart TV, which employs a new type of glass base panel, oxide-TFT. The material helps image data reach the diodes more quickly, thus producing the contrast, sharpness, and bright colors characteristic of OLEDs on a much larger scale. Price not set
