Embodiment Construction

[0067] As mentioned in the background, in the existing in-cell touch display panel, vertical lines appear on the display screen, which affects the display effect of the display panel. The inventors found that the reason for the vertical stripes on the display screen is that, in the direction perpendicular to the extension of the lead (hereinafter referred to as the horizontal direction), extending from the via hole electrically connected to the lead, the potential on the common electrode will increase with the distance from the via hole. increases and gradually decreases.

[0068] Specifically, refer to Figure 1-Figure 3 , figure 1 It is a top view of an existing in-cell touch display panel, the display panel includes a display area and a frame area, a plurality of common electrodes 11 are arranged on the display area, and a plurality of leads 13 electrically connected to the plurality of common electrodes 11, The lead 13 is electrically connected to the common electrode 11...

Abstract

The invention provides a display panel. The display panel comprises multiple public electrodes in a display area, and 2kn leads electrically connected with the public electrodes through multiple through holes. Each public electrode is electrically connected with 2k leads, wherein k is a natural number. The through holes are formed in an axial symmetry mode with the center line of the public electrodes as the symmetric axis. The leads electrically connected with each public electrode are symmetric about the center line of the public electrode. The arrangement modes of the through holes and the leads of each public electrode in the same public electrode row are similar, and the through holes and the leads are in the same area of the public electrode, so that the potentials of the two sides of the public electrode are the same in the extending direction of the public electrode row, it is ensured that the potentials of the adjacent public electrode boundary areas in the same public electrode row are the same, uniformity of the potentials in different areas of the public electrode is improved, vertical fringes on a display image are reduced or even eliminated, and the display effect of the display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background technique [0002] In the existing in-cell touch display panel, the common electrode layer is divided into a plurality of common electrodes, so that the common electrodes can be reused as touch electrodes. Wherein, each common electrode is electrically connected to the driving chip through a lead wire, so as to receive the common voltage signal and the touch signal outputted by the driving chip. [0003] However, the inventors found that in the existing in-cell touch display panel, vertical lines appear on the display screen during the display process, which affects the display effect of the display panel. Contents of the invention [0004] In view of this, the present invention provides a display panel and a display device, which reduce the vertical lines on the display screen and improve the display effect of...
