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 includes a flexible display panel in which a valid display area viewable to a user is extended or reduced, a touch sensing part overlapping the flexible display panel and including first sensing electrodes and second sensing electrodes intersecting the first sensing electrodes, a touch driver for providing driving signals to the first sensing electrodes, and detecting a touch by using sensing signals supplied from the second sensing electrodes, and a display driver for driving the flexible display panel such that an image is displayed in the valid display area. The touch driver controls at least one of hidden driving signals and hidden sensing signals, which correspond to a hidden display area of the flexible display panel which is not viewable to the user, to be different from at least one of the driving signals and the sensing signals, which correspond to the valid display area.

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.

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.
