Abstract

In a touch sensing display device, a plurality of sensor scanning lines extend in a first direction and sequentially receive a first voltage, and a plurality of sensor data lines extend in a second, different, direction. A plurality of sensing elements are formed in regions defined by the sensor scanning lines and the sensor data lines, and each sensing element transmits the first voltage from a corresponding sensor scanning line to a corresponding sensor data line responsive to an external touch. A sensing signal processor converts voltages of the sensor data lines into sensing data, and, a touch determining unit processes the sensing data corresponding to the sensor scanning lines by at least one scanning line to determine positions of touch regions generated during at least one frame.

Description

technical field [0001] The invention relates to a display device and a driving method thereof. More specifically, the present invention relates to a touch-sensitive display device and a driving method thereof. Background technique [0002] In general, a display device includes a plurality of pixels arranged in a matrix, and displays an image by controlling light intensity of each pixel according to given luminance information. Specifically, the liquid crystal display device includes a pixel electrode display panel, a common electrode display panel, and a liquid crystal layer with dielectric anisotropy located between the two display panels. In a liquid crystal display, when a voltage is applied to two electrodes, an electric field is generated in the liquid crystal layer. The strength of the electric field can be adjusted to control the transmittance of light passing through the liquid crystal layer, thereby obtaining a desired image. [0003] Recently, products having se...
