Abstract
Disclosed is a touch display panel, including an array substrate and a color film substrate, the array substrate includes a plurality of sub-pixels, a length-width ratio of the sub-pixel is substantially M:1, a short edge of the sub-pixel extends along a first direction, N color resistors are arranged on the color film substrate and corresponding to the sub-pixels, M and N are natural numbers greater than 1; the array substrate further includes a plurality of block-shaped common electrodes, each of the common electrodes overlaps with k*Z sub-pixels in the first direction, k is a positive integer, and Z is a least common multiple of M and N. By adopting the touch display panel with such a structure, a drive frame can be used to perform touch detection and display detection at the same time, which saves the detection debug time.
