Touch display screen and touch display device

Abstract

The invention discloses a touch display screen and a touch display device. The touch display screen comprises an array substrate, a color film substrate, a group of first electrode lines, a group of second electrode lines and transparent conductive shielding layers, wherein the array substrate and the color film substrate are symmetrically arranged; the group of first electrode lines is arranged on the array substrate or the color film substrate; the group of second electrode lines is arranged on the array substrate or the color film substrate and is in intersection arrangement with the group of first electrode lines; and the transparent conductive shielding layers are arranged on the color film substrate and are positioned on the group of first electrode lines and the group of second electrode lines, and one parts of the transparent conductive shielding layer corresponding to the first electrode lines and the second electrode lines are provided with hollow structures. Mutual inductance signals between the first electrode lines and the second electrode lines can pass through gaps of the hollow structure, and thus the implementation of the touch functional is ensured; and in addition, the transparent conductive shielding layers per se have conductivity, when a display screen is touched by external static electricity, electrostatic charges can be quickly led out and connected with the ground by the transparent conductive shielding layers, the electrostatic damage to the display screen due to the electrostatic charges can be prevented, and the display effect is further increased.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch display screen and a touch display device. Background technique [0002] At present, most mutual capacitive touch screens are plug-in, that is, the touch screen and the display screen are manufactured separately and then bonded together. This technology has the disadvantages of high production cost, low light transmittance, and thick module. With the development of science and technology, embedded touch screen technology has gradually become a new favorite of research and development, which means that the driving electrode lines and detection electrode lines used to realize the touch function are arranged on the substrate of the display screen. Compared with the external touch display device, the touch display device adopting the embedded touch screen technology has the advantages of thinner thickness, wider viewing angle, higher performance and lower cost....
