Abstract
A display device includes a display driving controller receiving input image data, a synchronization signal, and a voltage control signal, and generating image data based on the input image data and the synchronization signal, a display panel including pixels disposed on a display area and displaying an image on the display area based on the image data, and a touch sensor including sensing electrodes on a sensing area, and detecting a touch input generated in the sensing area by driving the sensing electrodes. The display driving controller generates a second level of the synchronization signal by changing a voltage level of the synchronization signal having a first level based on the voltage control signal, and provides the synchronization signal having the second level to the touch sensor. The touch sensor deactivates at least a partial area of the sensing area in response to the synchronization signal having the second level.
