Abstract: An array substrate and a touch display screen are disclosed in the present disclosure. The array substrate includes a plurality of touch cells, a plurality of touch lines, a first control unit, and a second control unit. Through this way, the present disclosure can solve the problem that touch lines fail to uniformly drive touch cells in each column due to the fact that the number of touch cells in the longitudinal direction is out of proportion with the number of pixel cells in the horizontal direction of each touch cell.

Abstract: The present invention provides a display panel and a chip. A frequency of a signal in a first frequency signal transmission line is greater than a frequency of a signal in a second frequency signal transmission line. A distance between a first signal input pad and a first signal output pad is smaller than a distance between a second signal input pad and a second signal output pad, and the distance between the second signal input pad and the second signal output pad is smaller than a distance between a third signal input pad and a third signal output pad. The invention can reduce the influence of the impedance of the signal transmission line on the signal.
