TOUCH CONTROLLED DISPLAY DEVICE
First Claim
1. A touch controlled display device comprising:
- a display panel comprising a first surface, a second surface opposing the first surface and a plurality of pixels between the first and second surfaces, each pixel comprising a transmission area and a display area, the transmission area being configured to transmit light therethrough;
an infrared source located on the side of the second surface of the display panel and configured to irradiate infrared light toward the first surface through the second surface; and
an infrared sensor located on the side of the second surface of the display panel and configured to detect infrared light from the first surface through at least one transmission area of the plurality of pixels.
