Sony announced a new LCD touchscreen supporting multi-touch.
With the success of the Apple iPhone, it seems no electronics company can bring out new portable devices without a touch screen interface. The new touch screens have to support of course multi-touch.
The new Sony LCD touchscreen uses a low-temperature polysilicon thin film transistor TFT process technology based on optical sensor arrays.
The current prototype display is 3.5 inch in size and has a resolution of 640 x RGB x 480 pixels. The optical touch sensor array supports up to 5 points. Finger and stylus input is supported.
