Abstract

The invention provides a display panel, which comprises a substrate and a conducting layer arranged on the substrate. The conducting layer comprises a plurality of touch electrodes, leads arranged between every two adjacent touch electrodes and virtual electrodes arranged between the adjacent touch electrodes and the leads. One end of each lead is electrically connected with the corresponding touch electrode, the other end of each lead is electrically connected with the touch chip, and the virtual electrodes are not electrically connected with any one of the touch electrodes and the leads, wherein the touch electrodes, the leads and the virtual electrodes all comprise grid structures of the same shape. According to the display panel, the shapes of the grid structures of the touch electrodes, the lead wires and the virtual electrodes are set to be the same, so that the light reflection effects of the touch electrodes, the lead wires and the virtual electrodes are the same, the phenomenon of uneven brightness of a screen is avoided to a great extent, and the display effect of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel. Background technique [0002] With the development of science and technology, smart devices such as mobile phones, tablet computers, digital cameras and smart wearable products with touch functions simplify human-computer interaction and bring users a high-quality user experience. Among them, touch screens mainly include resistive touch screens, capacitive touch screens, infrared touch screens and surface acoustic wave touch screens. Because capacitive touch screens have fast response time, good reliability and durability It has the advantages of high precision and is widely used in the above-mentioned smart devices. [0003] In order to reduce costs and increase production capacity, the single-layer metal self-capacitive touch screen has become a new research direction. The metal touch layer of the single-layer metal self-capacitive ...
