AU Optronics Corp (AUO) of Taiwan developed a 14-inch OLED panel with a pixel count of 1,920 x 1,080 (full HD) and a resolution of 157ppi and exhibited it at FPD International 2009.

"Technically, we can now start volume production of it," the company said. "If there is user demand for it, we will do that."

For the driver elements of the panel, AUO employed a low-temperature polycrystal Si-TFT (LTPS). Two transistors and one capacitor (2T1C) are used for each pixel.

The panel is a bottom emission type. Organic electroluminescent (EL) materials for RGB colors are applied by an evaporation method using a metal stencil mask.

The maximum screen luminance with an all-white signal is 200cd/m2. The contrast ratio of the panel is 100,000:1. It is capable of displaying 16 million colors and 72% of the NTSC color gamut. It supports a drive frequency of 120Hz.
