Large OLED screens are very expensive. This is the reason we have only started to see OLEDs become common in smartphones. There are a few OLED TVs on the market, but they are so expensive that they are far from common today.
A company called TVLogic has unveiled a pair of new OLED displays for computer users that have 15-inch screens. The two displays share many of the same features including 3G/HD/SD-SDI inputs and outputs, HDMI in, DVI in, and 1:1 pixel mapping.
The screens have 100,000:1 contrast ratios and 180-degree viewing angles among other features. The difference is that the LEM-150W is a 2D display while the TDM-150W is a 3D stereoscopic display. Pricing for the displays is unknown.
