Abstract
The present disclosure provides a touch display panel, a driving method thereof and a display device. The touch display panel includes a plurality of touch electrodes distributed in an array and multiplexed as common electrodes, a plurality of scanning lines extending in the row direction of the touch electrodes, a plurality of detection lines extending in the column direction of the touch electrodes, and first control circuits which are in one-to-one correspondence to the touch electrodes. The touch electrodes, the scanning lines, the detection lines and the first control circuits are arranged on a base substrate, each row of the touch electrodes is coupled with one scanning line through the corresponding first control circuit, each column of the touch electrodes is coupled with one detection line through the corresponding first control circuit, and the detection lines and the scanning lines are insulated from each other.
