Abstract: The present disclosure provides a display panel for a display device including a touch electrode divided into first touch unit sensors having a first size and second touch unit sensors having a second size different from the first size. When a horizontal or vertical size of a second touch unit sensor is compared with a first touch unit sensor, the vertical size of the second touch unit sensor is smaller than that of the first touch unit sensor when the horizontal size of the second touch unit sensor is larger than that of the first touch unit sensor and the horizontal size of the second touch unit sensor is smaller than that of the first touch unit sensor when the vertical size of the second touch unit sensor is larger than that of the first touch unit sensor. Therefore, an area deviation of touch unit sensors forming a touch electrode is minimized and thus uniform and superior touch performance may be provided.

Abstract: An in-cell touch display device. A panel has a plurality of data lines, a plurality of gate lines and a plurality of touch electrodes disposed thereon. A touch driving signal is applied to the plurality of touch electrodes when a driving mode is a touch mode. A data driver drives the plurality of data lines. A gate driver drives the plurality of gate lines. The gate driver sequentially outputs a scanning signal for driving the plurality of gate lines to the plurality of gate lines when the driving mode is a display mode, and outputs a load-free driving signal corresponding to the touch driving signal to at least one gate line when the driving mode is the touch mode. A level shifter generates the load-free driving signal. A multiplexer inputs a scanning voltage or the load-free driving signal to the gate driver depending on the driving mode.
