Abstract
The present invention provides a touch panel used in a display device. The touch panel of the present invention is configured to display images and to receive as well as to process instructions inputted by user'"'"'s touches. A display substrate partially overlaps with an image driving circuit substrate of the touch panel. A touch sensing circuit is disposed on the inner side of the display substrate. A touch sensing processor is disposed on the inner side of a touch sensing circuit and is also electrically coupled to the touch sensing circuit. Consequently, the thickness of the touch panel as well as the overall thickness of the display device is reduced.
