Abstract: A display device includes a display including a plurality of pixels and an input sensor for sensing an input of a user. The display device includes: a driving controller for providing the display with a scan signal and a data signal according to a driving frequency; an input controller for providing a touch driving signal to the input sensor; a horizontal synchronization signal information line connecting the driving controller and the input controller, the horizontal synchronization signal information line transmitting a horizontal synchronization signal therethrough; and a vertical synchronization signal information line connecting the driving controller and the input controller, the vertical synchronization signal information line transmitting a vertical synchronization signal therethrough. Amplitude of the vertical synchronization signal or the horizontal synchronization signal varies according to the driving frequency.

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.

Abstract: A display device and a method of driving a display device. The display device includes a housing, a display touch module including a non-exposed area covered by the housing, an exposed area located outside the housing, and an active area over the non-exposed area and the exposed area. The display touch module includes a display member configured to display an image and a touch member on the display member configured to sense a touch input. The display device also includes a boundary determining member configured to sense a capacitance of the touch member and calculate coordinates of an exposure boundary between the exposed area and non-exposed area of the display touch module. The display device is configured to adjust a display range of the active area according to the coordinates of the exposure boundary calculated by the boundary determining member.
