Abstract

A touch display device comprises a first substrate, a second substrate and a liquid crystal layer. A plurality of pixel units are formed on the first substrate. The second substrate comprises a shading structure, the touch display device further comprises a plurality of first conductive electrodes and a plurality of second conductive electrodes, the first conductive electrodes and the second conductive electrodes are mutually insulated, and the first conductive electrodes and / or the second conductive electrodes correspond to a shading structure area. According to the touch display device, a Metal Mesh process is adopted to form a first conductive electrode and a second conductive electrode. The first conductive electrode and the second conductive electrode both correspond to the shading structure area. The influence of the first conductive electrode and the second conductive electrode on the penetration rate is avoided. The penetration rate can reach 100% basically, and meanwhile the optical problems such as interference fringes can be prevented from being generated.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a touch display device. Background technique [0002] With the continuous advancement of display technology, touch display devices have gradually pervaded people's lives. At present, indium tin oxide (Indium Tin Oxides, ITO) transparent conductive film is generally used as the touch sensing electrode and touch driving electrode of the touch display device. The problem, on the other hand, will have a greater impact on the transmittance (Tr) of the display device, which is that the transmittance of the display device is relatively low. [0003] A new generation of Metal Mesh (metal grid) touch sensors is gradually emerging. Metal-Mesh touch technology uses a metal grid as the conductive layer of the conductive film. The metal grid is a shape formed by crossed conductive wires regular grid. The use of Metal-Mesh touch technology can greatly increase the tra...
