Problems solved by technology

[0005] The disadvantage of the prior art is that, if figure 2 As shown, the coupling capacitance formed by the touch sensing lines parallel to the plane and the sensing electrodes used in the existing capacitive screen needs to occupy a large detection unit area. Since the coupling capacitance is located in the non-display area of ​​the display screen, the touch The aperture ratio of the control panel affects the brightness of the display device

Abstract

An array substrate, a touch screen panel and a display device are provided. The array substrate includes a plurality of gate lines, a plurality of data lines, a plurality of touch sensing units, and each touch sensing unit comprises a touch scanning line, a touch sensing line, a first transistor and a sensing electrode, the touch scanning line is connected with a gate electrode and a drain electrode of the first transistor and the sensing electrode is connected with a source electrode of the first transistor; the touch sensing line and the sensing electrode are provided in different layers, spaced apart by an insulating layer and have an overlapping region. This array substrate decreases areas of non-display regions on the array substrate, increases aperture ratio of the touch screen panel and in turn enhances brightness of the display device.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to an array substrate, a touch panel and a display device. Background technique [0002] With the rapid development of display technology, touch screen panels (TouchScreenPanel) have gradually spread throughout people's lives. Currently, touch panels can be classified into resistive, capacitive, infrared and surface acoustic wave types according to their working principles. Among them, the capacitive touch panel is widely used in the industry because it can realize real multi-point control and high sensitivity. [0003] Capacitive touch screens can be divided into three types according to their composition: external touch screens, surface-covered touch screens, and built-in touch screens. Among them, the plug-in touch screen is produced separately from the touch screen and the display screen, and then bonded together to form a touch-enabled LCD screen. The p...
