Abstract
A display device has a display panel generating visible light and generating infrared rays; a plurality of detectors detecting a change in an intensity of the infrared rays generated by the display panel; and the plurality of detectors recognizing a touch applied to the display panel in dependence upon the change detected in the intensity of the infrared rays.
Claims19
A display device having a touch screen function, the display device comprising:
- a display panel which emits light and displays an image;
- and
- a plurality of detectors which detect a touch applied on the display panel by detecting intensity of the light emitted by the display panel.
