Problems solved by technology

Because some inorganic layers in the display panel are generally formed by chemical vapor deposition (CVD) process, when the frame of the display panel is narrow, the border of CVD may cover the transfer hole, resulting in the gap between the touch trace and the transfer trace. Increased contact resistance affects touch performance

Abstract

The embodiment of the invention discloses a touch display panel and a touch display device. The touch display panel comprises: a substrate including a display area and a non-display area; a light emitting device located in the display area; a packaging layer which covers the light-emitting device and at least part of the non-display area; a touch layer which is located on the side, away from the light-emitting device, of the packaging layer, and comprises a plurality of touch electrodes; and a plurality of touch control wires which are directly and electrically connected with the touch control electrodes, and extend to the non-display area; wherein the non-display area comprises a first area and a second area, a through hole and/or a groove are/is formed in at least part of the film layer in the first area, the touch wire extends along the surface of the first area and extends to the second area, and the second area is located on the side, away from the display area, of the first area. According to the technical scheme of the embodiment of the invention, the resistance can be prevented from being increased during touch wiring, and the touch performance is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a touch display panel and a touch display device. Background technique [0002] Since touch operation is a simple and convenient way of human-computer interaction, more and more products integrate the touch function into the display panel. According to the structure, the touch panel can be divided into Add on Mode Touch Panel, On Cell Touch Panel and In Cell Touch Panel. Among them, the in-cell touch panel is to arrange the touch electrodes of the touch panel inside the display panel, which can reduce the overall thickness of the module and greatly reduce the production cost of the touch panel, so it has been widely used. [0003] When preparing the display panel, in order to realize the narrow frame design of the display panel, a bending area is usually set in the non-display area, and transfer holes are provided on both sides of the bending area...
