Touch display panel and touch display device

Abstract

A touch display panel and a touch display device, wherein the touch display panel is provided with a display area and a non-display area, the non-display area includes: a frame area and a binding area, and includes: a plurality of first electrodes arranged in an array and a plurality of common signal lines extending at least partially along the column direction, the first electrode is located in the display area, the plurality of first electrodes correspond one-to-one to the plurality of common signal lines, the first electrodes are electrically connected to the corresponding common signal lines, the common signal lines include: a first signal line at least partially located in the display area and a second signal line located in the frame area, the first electrode of the i+1th row is located on the side of the first electrode of the i-th row close to the binding area, the resistance of the first signal line of the common signal line connected to the first electrode of the i+1th row is less than the resistance of the first signal line of the common signal line connected to the first electrode of the i-th row, and the resistance of the second signal line of the common signal line connected to the i+1th row is greater than the resistance of the second signal line of the common signal line connected to the first electrode of the i-th row.
