Abstract: A display device includes a display portion, a display driver, a touch sensing portion, and a touch driver. The display portion includes data lines, scan lines, and pixels connected to the data lines and the scan lines. The display driver provides data signals to the data lines and sequentially provides scan signals to the scan lines. The touch sensing portion includes sensing electrodes. The touch driver senses a touch input based on a change of a capacitance between the sensing electrodes and calculates a movement speed of the touch input. When the movement speed of the touch input is greater than a reference speed, a first period in which the scan signals and the data signals are provided is reduced in a frame period in which a frame image is displayed.

Abstract: A touch sensor includes a touch sensing column, a touch sensing row, and connectors. The touch sensing column has a plurality of first touch sensing electrodes extending in one direction. The touch sensing row has a plurality of second sensing electrodes extending in a direction intersecting the touch sensing column. The connectors connect adjacent first touch sensing electrodes or adjacent second touch sensing electrodes. Here, at least some of the first touch sensing electrodes or the second touch sensing electrodes include a first region connected to the connectors and having a first line resistance, and a second region adjacent the first region and having a second line resistance. The first line resistance is different from the second line resistance.
