Next week Samsung will show off a prototype of a 40-inch OLED panel. OLED displays use less power than platpanels because they don't require a backlight and also offer higher resolutions than LCD displays.
For the moment OLED panels are mainly used in small devices like cell phones.
This latest prototype sports a 1,280-by-800-pixel resolution and a maximum screen brightness of 600 nits (A NIT is a measurement of light in candelas per meter square). The black-and-white contrast ratio is 5,000 to 1. The panel is 2.2 centimeters thick, and it can be fit into televisions that are less than 3 centimeters deep, Samsung said.
