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 abnormal contact between the touch trace and the touch terminal , affecting 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 which comprises a display area and a non-display area; a light-emitting device located in the display area; a packaging layer which comprises at least one inorganic layer and at least one organic layer which are stacked; a touch layer which is positioned on one side, far away from the light-emitting device, of the at least one inorganic layer; multiple touch wires which extend to the non-display area in the first direction; the step area comprises a first area and a second area, the first area comprises at least one retaining wall, the second area comprises a plurality of touch terminals, and at least part of the touch terminals are electrically connected with the touch wires in a one-to-one correspondence mode; the second area comprises at least one blocking column, and the blocking column extends in the second direction; the blocking columns are used for blocking at least one inorganic layer, located between the touch control layer and the substrate, in the packaging layer from extending to the touch control terminals. According to the technical scheme provided by the embodiment of the invention, the risk of abnormal contact between the touch wire and the touch terminal can be reduced, and the touch performance is improved.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, 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 set on both sides of the bending area to transfer the tou...
