A touch display panel and a touch display device

Abstract

The invention provides a touch display panel. The touch display panel is characterized by comprising a base plate, a plurality of pieces of first touch electrodes and a plurality of pieces of first lead wires, wherein the base plate comprises a display area and a non-display area surrounding the display area; the first touch electrodes are located in the display area, and the first lead wires which are located in the non-display area are in one-to-one electric connection with the plurality of pieces of first touch electrodes; the first touch electrodes extend along a first direction and are arranged sequentially along a second direction, and the plurality of pieces of first lead wires extend along the second direction and are arranged sequentially along the first direction; the widths, along the first direction, of the plurality of pieces of first lead wires are gradually reduced when approaching the display area. By adopting the touch display panel provided by the embodiment of the invention, the interference of a touching object to touch electrode lead wires in the touch display panel can be averaged, voltage transmitted on different touch electrode lead wires can be prevented from being uneven, and the touch accuracy of the touch display panel can be improved.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch display panel and a touch display device with special structure touch leads. Background technique [0002] As an input medium, the touch display panel is currently the simplest and most convenient way of human-computer interaction. Therefore, more and more products integrate the touch display function into the liquid crystal display. In the existing technology, such as figure 1 Shown is a schematic diagram of a touch display panel in the prior art. The touch display panel 100 generally includes a substrate, and the substrate generally includes a display area 101 and a non-display area 103 surrounding the display area 101 . The display area 101 generally includes a plurality of touch electrodes 105 (in figure 1 It is only schematically described that the touch electrodes 105 extend along the first direction D1 and are arranged parallel to each other along t...

Problems solved by technology

In the prior art, when a touch object (such as a human finger) touches the touch display panel, especially when the touch position is close to the border between the display area 101 and the non-display area 103, it is located in the non-display area 103 The closer the touch electrode leads 1051 to the display area 101 are, the easier it is to be disturbed by the touch object. This interference is directly reflected in that the voltage signals transmitted on different touch electrode leads 1051 are different, and the resulting The impact is a drop in touch accuracy
