Abstract

A display device includes a display layer, a touch layer including a plurality of driving electrodes and a plurality of sensing electrodes, and a touch driving circuit supplying touch driving signals to the plurality of driving electrodes, receiving touch signals from the plurality of sensing electrodes, and generating a touch sensing signal including first and second touch sensing signals. The touch driving circuit receives one of the touch signals, detects first sensed voltages of the one touch signal every first cycle of the first touch sensing signal to calculate a phase delay amount of the one touch signal, delays a phase of the second touch sensing signal based on the phase delay amount, calculates second sensed voltages of the one touch signal every second cycle of the second touch sensing signal different from the first cycle, and recognizes a touch input based on the second sensed voltages.
