Embedded touch array substrate and liquid crystal display panel

Abstract

The invention provides an embedded touch array substrate and a liquid crystal display panel. The embedded touch array substrate comprises a plurality of pairs of grid scan lines, a plurality of pairs of data lines, pixel switches, pixel electrodes, touch transmitting lines, touch receiving lines and touch units. The grid scan lines and the data lines are arranged in a staggered manner; the pixel switches are respectively electrically connected with the adjacent grid scan lines and the adjacent data lines; the pixel electrodes are electrically connected with the pixel switches; each touch transmitting line is arranged between the two corresponding adjacent pairs of grid scan lines; each touch receiving line is arranged between the two corresponding adjacent pairs of data lines and intersects with the touch transmitting lines; the touch units are electrically connected at intersections of the touch transmitting lines and the touch receiving lines. The embedded touch array substrate and the liquid crystal display panel have the advantages that the grid scan lines and the data lines are in a double-routing mode, so that independent routing spaces can be provided for the touch transmitting lines and the touch receiving lines, interference among driving signals and touch signals of the panel can be reduced, and the touch sensitivity can be improved; the signal amplitude is decreased, so that power consumption of the panel can be reduced.

Description

technical field [0001] The invention relates to the field of image display, in particular to an in-cell touch array substrate and a liquid crystal display panel. Background technique [0002] Recently, liquid crystal display (Liquid Crystal Display, LCD) technology has developed rapidly, and great progress has been made in terms of screen size and display quality. LCD has the characteristics of small size, low power consumption, and no radiation. Occupied a dominant position in the field of flat-panel display. [0003] The touch LCD screen is one of the important carriers that integrate the input and output terminals. In recent years, demand for touch-screen LCDs has surged with the advent of a range of products, including small, lightweight handheld devices. [0004] The development direction of touch technology is low cost, high yield, large size, high reliability and so on. In order to achieve this goal, in terms of structural technology, built-in touch structures suc...

AI Technical Summary

Problems solved by technology

Among them, since the distance between the touch emission line 3' and the gate scanning line 1' is relatively close, and the distance between the touch reception line 4' and the data line 2' is relatively close, there is interference between the panel driving signal and the touch signal, which makes the touch sensitivity Greatly reduced
