Abstract
A display device includes: a display panel including a display layer and a touch layer; and a touch driving circuit connected to first electrodes and second electrodes of the touch layer. The touch driving circuit is to: determine frequencies of touch driving signals to be supplied to the first electrodes; assign the frequencies to the touch driving signals in an ascending order; determine a first phase of each of the touch driving signals that minimizes a cumulative value of PAPRs while sequentially varying phases of the touch driving signals; update the phases of the touch driving signals from the first phase to a second phase that minimizes the cumulative value of the PAPRs by sequentially varying the first phase of each of the touch driving signals; and output the touch driving signals based on the frequencies assigned to the touch driving signals, respectively, and the second phase.
