Abstract:
Discussed is a display device. The display device includes a display panel including a plurality of gate lines and a plurality of data lines, a timing controller temporally dividing one frame period and driving the display panel such that a display mode for displaying an image in the display panel and a touch mode for sensing the user touch are alternately driven, a gate driver, and a data driver. Some of the gate lines and some of the data lines overlap each of a plurality of touch electrodes that are units for sensing a user touch. The gate driver simultaneously turns on a plurality of switching elements respectively connected to the gate lines overlapping each touch electrode in the touch mode. The data driver outputting display data having the same level to the respective data lines overlapping each touch electrode when the switching elements are turned on.
