Abstract
A display device may include a display panel, a plurality of pixels that are disposed on the display panel, a plurality of sensing units that are disposed on the display panel to generate sensing signals based on touch of the display panel, a sensing signal processor that receives the sensing signals and performs predetermined signal processes to generate sensing data, and a touch detection unit. The touch detection unit may include a first controller that determines, based on the sensing data from the sensing signal process, whether or not there is a touch occurrence of the sensing units and whether or not the sensing signal is in an appropriate state. The touch detection unit may also include a second controller that determines the touch occurrence and touch positions on the sensing units based on the sensing data and controls the sensing signals to be in the desired range.
