Abstract:
A touch screen panel using a thin film transistor (TFT) photodetector includes a touch panel including a plurality of unit patterns for sensing light reflected by a touch by using a TFT photodetector including an active layer formed of amorphous silicon or polycrystalline silicon on an amorphous transparent material, and a controller configured to scan the plurality of unit patterns and read touch coordinates as a result of the scanning.
