Abstract: The present disclosure provides a touch display device and a method for driving the touch display device. The touch display device includes an array substrate and a color film substrate arranged opposite to the array substrate; a touch electrode array disposed on the array substrate, and a plurality of touch sensing electrodes arranged along a first direction and disposed on the color film substrate. The touch electrode array includes M×N touch electrodes. The touch electrodes are insulated from each other. The touch sensing electrodes extend along a second direction perpendicular to the first direction, and the touch sensing electrodes are insulated from each other. An orthographic projection of each of the touch electrodes to a plane where the touch sensing electrodes are located at least partially overlaps with one of the touch sensing electrodes.

Abstract: A shift register, a driving circuit and a display device are provided. The shift register comprises an output circuit, a node control circuit, and a first node charging circuit. The output circuit provides a signal at a first clock signal terminal or a signal at a first reference voltage terminal to a gate signal output terminal under a control of a signal at a first node or a control of a signal at a second node. The node control circuit controls levels of the signal at the first node and at the second node to be opposite. The first node charging circuit includes a first control terminal, and provides a signal at a first fixed voltage terminal to the first node under a control of a signal at the first control terminal during a charging period of the first node in a non-scanning period.
