Array substrate and manufacture method and display device thereof

Abstract

The embodiment of the invention provides an array substrate and a manufacture method and a display device thereof and relates to the technical field of display. The aperture ratio of the display device can be improved. The touch type array substrate comprises a grid line, a data line, a pixel electrode, a thin-film transistor and a common electrode, wherein the pixel electrode and the thin-film transistor are arranged in a pixel region defined by the grid line and the data line. The array substrate further comprises a first sensing line and a second sensing line, wherein the first sensing line and the second sensing line are arranged in an upper layer and a lower layer correspondingly and parallelly, and both the first sensing line and the second sensing line are arranged in a way of crossing an electrode bar on the common electrode; and the first sensing line is arranged between a pattern layer in which the second sensing line is and a pattern layer in which the common electrode is, and the second sensing line is electrically connected with the common electrode.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, touch display devices that integrate input and output terminals have appeared. With the advent of a series of products such as small and light hand-held touch devices, the market demand for touch display devices has surged . Among the various existing touch display devices, the projected capacitive touch device in the capacitive touch device has become the main development direction because of its advantages of real multi-touch and high sensitivity. [0003] Such as figure 1 As shown, it is an array substrate of a mutual inductive capacitive touch display device in the existing projected capacitive touch screen, and the array substrate includes gate lines 11, data lines 12, gate lines 11 and data lines 12 Pixel electrode 1...

AI Technical Summary

Problems solved by technology

[0004] The inventors found that, in the array substrate of the above-mentioned touch display device, a sensing line is added to the substrate on the same layer as the data line, the introduction of which will reduce the aperture ratio of the display device, and in order to realize the sensitivity , the sensing line needs to be wide enough to form a large enough coupling capacitance with the common electrode, which further reduces the aperture ratio of the display device
