Samsung Optical Sensor in Pixel LCD Has Advanced Touch Support

People may or may not remember when we drew attention to the SUR40 touch surface, the one over here.

Samsung is now mass producing the 40-inch LCD that it is equipped with and which is quite advanced as far as touchscreens go.

The panel boasts the Optical Sensor in Pixel technology, which lets the screen use infrared sensors to detect reflected images of an object placed on the surface.

Each pixel has this optical sensor, which is why more than 50 touch points can be detected and accurately tracked at once.

This is possible even at Full HD resolution (1,920 x 1,080 pixels) and works just fine with keyboards and mice.

The SUR40 is up for pre-order and will sell widely starting early 2012. Samsung should start to extend the use of the feature to other products soon after.
