The OLED is 7.6", which means it's the same one used in Kodak's wireless OLED frame - and made by CMEL -  16:9 aspect ratio, 800x480 resolution, white to black contrast ratio of 30,000:1.

These are expensive, professional devices - ranging from 2100$ to 2400$, depending on battery configuration and model type.
