Abstract

The invention provides an array substrate. The array substrate comprises a substrate body, wherein a signal transmission line, a first insulating layer, a second insulating layer, a pixel electrode layer and a public electrode layer are located on the substrate body, the first insulating layer is located between the signal transmission line and the public electrode layer, the second insulating layer is located between the pixel electrode layer and the public electrode layer, the dielectric constant of the first insulating layer is smaller than or equal to that of the second insulating layer, and the signal transmission line is electrically connected with the public electrode layer. By means of the array substrate, the parasitic capacitance between the signal transmission line and the public electrode layer or the pixel electrode layer is reduced. Due to the reduction of the parasitic capacitance, the reduction of loads on a touch control panel is facilitated, the charging time of a touch control electrode is shortened as well, and the touch control sensitivity of the touch control panel is improved. The invention further provides a display panel and a display device.

Description

Technical field [0001] The present invention relates to the field of liquid crystal display devices, in particular to an array substrate, a display panel and a display device. Background technique [0002] Compared with the touch display device in which the touch panel is arranged on the liquid crystal display panel, the touch display device integrating the touch display device and the liquid crystal display panel can reduce the use of substrates and has the advantage of thinner thickness, which has become the mainstream touch display today. Device. The touch display device integrated with the touch display device and the liquid crystal display panel includes an on-cell structure and an in-cell structure. Among them, the in-cell structure refers to embedding the touch panel function into the TFT array substrate. [0003] Currently, the touch electrodes of the self-capacitive in cell touch screen are multiplexed with the common electrodes. Such as figure 1 As shown, the common el...
