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.

Abstract: A liquid crystal display device includes a signal processor using an (n?1)-th conversion signal corresponding to an (n?1)-th raw image signal of an (n?1)-th frame to correct an n-th raw image signal of an n-th frame, and outputting an n-th corrected image signal, the (n?1)-th raw image signal. The n-th raw image signal, and the n-th corrected image signal each have ‘a’ bits and the (n?1)-th conversion signal has ‘b’ bits. The ‘b’ bits is smaller than the ‘a’ bits (a>b). A liquid crystal panel displays an image corresponding to the n-th corrected image signal.
