LONDON – Samsung Electronics Co. Ltd. has started making a 40-inch sized LCD panel that includes an infra-red optical sensor in each pixel for better touch sensitivity.
All of the input functions of a keyboard, mouse or scanner can be carried out on the panel which can detect up to 50 touch points on the screen while displaying high definition resolution images.
The optical-sensor-in-pixel LCD panel has been installed in the Samsung SUR40 display which has been developed by Microsoft and Samsung as table-format PC under the name Microsoft Surface.

Interesting - I know this company as one of scale and not of innovation. But let us see how this goes.

It could maybe detect where you are sitting to optimise 3d images and stereo audio. Your Tv now watching you!

Why do we need 50 touch points ? Does it have any significance in any application ?

If you have a display as a table with four people sat around all touching the screen and moving images by drag and drop......
4 people times 2 hands times 5 fingers = 40 contact points.

A Samsung product...I rely on it.
What is the specific advantage of having multitouch points?

Samsung is embedding an infra-red sensor to each pixel for improving touch sensitivity. It's an interesting idea although I haven't figure out the benefit. Nonetheless, there is a challenge to the implementation. Will the heat generated in the surroundings, which include the internal electronics, affect the detection?
Nonetheless, if these infra-red sensor is replaced with CCD, the application areas will be tremendous.

I wonder what chaos will be triggered when sunlight passes across this screen. With objects between the screen and the sun casting shadows, there might be some very interesting outcomes.
