Problems solved by technology

However, with the continuous improvement of user requirements for panel shape design, the demand for narrow borders limits the routing space in the step area, which leads to a small distance between the touch signal lines extending in the step area. Problems such as etching residues are prone to occur in the process, resulting in a short circuit of the touch signal line

Abstract

The embodiment of the invention provides a touch display panel and a touch display device, relates to the technical field of display, and increases the distance between touch signal lines in a step area. The panel comprises a display area and a non-display area. The non-display area comprises a step area and a non-step area, and the step area comprises a wiring area, a bending area and a functional area; The panel also comprises a retaining wall which is arranged around the display area in the non-display area; touch electrodes and touch signal lines, wherein the touch signal lines extend to the functional area from the non-step area, the routing area and the bending area, the parts, located in the non-step area, of the touch signal lines are touch routing lines, the touch routing lines are located on the sides, close to the display area, of the retaining walls, and the parts, located in the step area, of the touch signal lines are touch leads; an electrostatic shielding signal line which is located in the non-display area, wherein the part, extending in the second direction in the step area, of the electrostatic shielding signal line is located on the side, away from the display area, of the retaining wall, and the second direction is the extending direction of the retaining wall in the step area.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a touch display panel and a touch display device. 【Background technique】 [0002] In order to realize the touch function, touch electrodes and touch signal lines connected to the touch electrodes are provided in the touch display panel. Usually, the touch signal lines extend along the left frame and the right frame of the touch display panel to the step area . However, with the continuous improvement of user requirements for panel shape design, the demand for narrow borders limits the routing space in the step area, which leads to a small distance between the touch signal lines extending in the step area. Problems such as etching residues are prone to occur in the process, resulting in a short circuit of the touch signal line. 【Content of invention】 [0003] In view of this, the embodiments of the present invention provide a touch display panel and a touch display ...
