Abstract

The embodiment of the invention discloses an array substrate, a manufacturing method thereof, a display panel and a display device. The array substrate comprises a substrate base plate, a common electrode layer, a first insulating layer, a pixel electrode located on the side deviating from the substrate base plate, of the first insulating layer, and touch signal lines located on the side deviating from the substrate base plate, of the first insulating layer, wherein the common electrode layer comprises multiple common electrode units, the common electrode units are reused as touch electrodes at a touch stage, the first insulating layer is located on the side, deviating from the substrate base plate, of the common electrode layer, each common electrode unit and at least one touch signal line are connected through via holes formed in the first insulating layer, and the touch signal lines and the pixel electrode are arranged in an insulated mode. By adopting the technical scheme, adjustment of a film layer structure of the array substrate in the prior art is achieved, the number of insulation layers is decreased, and accordingly the effect of improving the penetration rate is achieved.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to an array substrate and a manufacturing method thereof, a display panel and a display device. Background technique [0002] In a liquid crystal display device, a panel with a touch function is used in order to allow a user to perform related operations while watching a screen. In the prior art, the touch function is realized by adding a layer of touch electrode layer on the basis of the display panel or integrating the touch electrode layer inside the display panel. [0003] In the method of integrating the touch electrode layer inside the display panel, not only the touch electrode layer but also an insulating layer must be added inside the display panel, so that the touch electrode layer can be insulated from other conductive layers. [0004] The transmittance of the liquid crystal display device is affected by the transmittance of the array substrate, the transmi...
