Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0042] refer to figure 1 with figure 2 , figure 1 is a structural schematic diagram of a display panel in the prior art, figure 2 It is a structural schematic diagram of another display panel in the prior art. The base substrate 1 of the display panel is provided with a plurality of gate lines 11 and data lines 12 intersecting. The gate lines 11 and data lines 12 cross to define multiple 14 sub-pixels. When making a display panel with a touch function, the touch trace 13 can be arranged on the same layer as ...

Abstract

The invention discloses a touch display panel and a touch display device, wherein the touch display panel comprises a plurality of touch lines and a plurality of data lines which are arranged on a substrate, wherein the touch lines and the data lines extend along a first direction, the data lines and the touch lines are arranged on different layers, and at least one data line is overlapped with the touch lines; the pixel units which are arranged in an array; a plurality of touch electrodes, wherein each touch electrode covers a plurality of pixel units, each pixel unit comprises a plurality ofsub-pixels, and at least one pixel unit comprises a sub-pixel provided with a notch area; each touch routing line comprises a plurality of extension subsections which extend to the notch area; at least one extending part of each touch wire is electrically connected with the touch electrode through the via hole of the notch area, and the via hole penetrates through the insulating layer between thetouch wire and the touch electrode. The invention provides the touch display panel and the touch display device which solve the problem that touch wires of different touch electrodes in the touch display panel interfere with one another.

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] At present, the display device is usually integrated with touch function and display function. The touch panel can be integrated on the display panel by "On-cell" method, or the touch function can be integrated in the display panel by "In-cell" method. Apparently, the in-cell touch display panel with integrated touch function using the "In-cell" method is thinner and lighter. [0003] In the existing in-cell touch display panel, the common electrode layer can be divided into multiple common electrodes, and the common electrodes are electrically connected to at least one touch trace. In the display stage, the common electrodes are used to receive common voltage signals. In the touch stage, the common electrodes are multiplexed as touch electrodes for outputting touch driving signals. [0004...
