Array substrate, display panel and display device

Abstract

The embodiment of the invention discloses an array substrate, a display panel and a display device. The array substrate comprises an underlayment substrate, and a first wiring layer and a transparentconductive layer which are arranged on one side of the underlayment substrate. The first wiring layer comprises a plurality of touch signal lines and data signal lines, the transparent conductive layer comprises a plurality of common electrodes, and the common electrodes are multiplexed as touch electrodes. The transparent conductive layer further comprises a plurality of conductive blocks, and the conductive blocks are electrically connected with the corresponding touch signal lines through at least one via hole. The distance between a first edge of each conductive block and a first edge of the adjacent first common electrode block is d1, the distance between a first edge of each touch signal line and a first edge of the adjacent first common electrode block is d2, the distance between asecond edge of each touch signal line and a first edge of an adjacent second common electrode block is d3, and d2 > = d1 > d3. According to the scheme of the embodiment of the invention, the lateral parasitic capacitance of the touch signal lines and the common electrodes can be reduced, so that the load of the touch signal lines is reduced, and the risk of poor display is reduced.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to an array substrate, a display panel and a 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 liquid crystal display panel. According to the structure, the touch panel can be divided into Add on Mode Touch Panel, On Cell Touch Panel and InCell Touch Panel. Among them, the in-cell touch panel is to arrange the touch electrodes of the touch panel inside the liquid crystal 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] In the prior art, in order to further reduce the structure and cost of the liquid crystal display panel, a Touch and Display Driver Integration (TDDI) technology has been developed, that is, the touc...

Problems solved by technology

In the existing design, the touch signal line is located between two adjacent common electrodes and is very close to the common electrodes, resulting in a strong lateral electric field from the touch signal line to the left and right common electrodes, so the touch signal line heavy load

Especially for screens with a high refresh rate (such as 90Hz), the large load causes a large delay in touch control, which cannot keep up with the refresh rate of the screen, resulting in poor display
