Abstract: A method for driving a display device including a display panel including a first and a second display area each of which is divided into a plurality of display blocks and n touch blocks comprises a first and a second step. The first step drives the respective display blocks of the first display area sequentially, drives at least one touch block after driving the display blocks, and generates a first touch report after driving all of the n touch blocks. The second step drives the respective display blocks of the second display area sequentially, drives at least one touch block after driving the display blocks, and generates a second touch report after driving the n touch blocks again. The first and the second step are processed within one frame period, and the one frame period includes a vertical blanking interval void of input image data.

Abstract: A display device, a method of driving the same, and a driving circuit of the display device are discussed. The display device includes a display panel including a pixel array, in which touch sensors are embedded, a timing generator that determines a normal driving mode and a low-speed driving mode based on a mode control signal and generates a first touch sync signal in the low-speed driving mode, a display driver writing pixel data to the pixel array in response to the first touch sync signal only in the display periods of the data write frames in the low-speed driving mode, and a touch driver driving the touch sensors in response to the first touch sync signal in the touch periods of the data write frames and at least a portion of the data hold frame in the low-speed driving mode.
