Abstract

A touch panel comprises a substrate as well as a first electrode layer and a second electrode layer which are arranged on one surface of the substrate, wherein the first electrode layer comprises multiple first main touch electrode wires for emitting touch signals and multiple first invisible lines connected with the multiple first main touch electrode wires; the second electrode layer comprises multiple second main touch electrode wires for receiving the touch signals; the multiple first main touch electrode wires are mutually crossed to form a mesh structure, the first invisible lines are provided with multiple first breaking points, one first node is formed by every two mutually crossed first main touch electrode wires, part of first nodes are connected with two first invisible lines respectively, and a vertical distance is formed between the first node and a connecting line of any points in two first breaking points, close to the first node, of the two first invisible lines and is larger than 100 micrometers. According to the touch panel and the touch display screen, the Moire effect can be effectively reduced, and the accuracy rate of position identification is increased.

Description

technical field [0001] The invention relates to a touch panel and a touch display screen comprising the touch panel. Background technique [0002] A touch display is an inductive device that can receive input signals such as touch, and is an attractive new information interaction device. The development of touch screen technology has aroused widespread concern in the information media circles at home and abroad, and has become a rising high-tech industry in the optoelectronic industry. [0003] The touch electrode layer is a crucial component of the touch display screen. At present, the touch electrode layer of the touch display screen is mainly formed by ITO (indium tin oxide) or mesh metal wires. However, ITO as a touch electrode layer not only requires high technology and equipment, but also wastes a lot of ITO materials in the manufacturing process, and produces a large amount of industrial waste liquid containing heavy metals. To improve the above situation, an altern...
