Abstract: Disclosed is a display device including a display panel, an input sensing layer, a display controller that receives a vertical synchronization signal and a horizontal synchronization signal and controls an operation of the display panel depending on the vertical synchronization signal and the horizontal synchronization signal, and a sensing controller that receives the vertical synchronization signal and the horizontal synchronization signal and generates a driving control signal for driving the input sensing layer. One frame of the vertical synchronization signal includes a first vertical section and a second vertical section in which the display controller transmits a data signal to the display panel. The sensing controller determines an operating frequency of the driving control signal based on a horizontal synchronization signal, which is included in a first horizontal section overlapping with the first vertical section, in the horizontal synchronization signal.
