Claim Text:
1. A display device, comprising: a display panel comprising: a timing controller temporally dividing each frame period of a plurality of frame periods into a touch sensing period for sensing the user touch and a display mode period for displaying an image in the display panel, and driving the display panel such that the display mode period and the touch sensing period are alternately driven; a gate driver; and a data driver configured to provide display data to the plurality of data lines, wherein a touch sensing block of the plurality of touch sensing blocks is initialized during an initialization period before the touch sensing period of one frame period, wherein during the initialization period the gate driver simultaneously turns on a plurality of switching elements respectively connected to the gate lines overlapping the touch sensing block while the data driver outputs display data having a same level to the respective data lines overlapping the touch sensing block, and wherein at least two touch sensing blocks are initialized in different frame periods.
