Problems solved by technology

However, since the touch sensing layer 25 is made of metal conductive material and generally has a relatively flat surface 25a, when the light is incident on the touch sensing layer 25, there will be a mirror reflection phenomenon, causing the viewer to watch the touch sensing layer 25 from certain angles. When the touch display device 20 is controlled, there will be bright and dark areas at intervals, and there will be interference fringes of light and dark, which will affect the display quality of the touch display device 20

Abstract

The touch display device includes a display substrate, a transparent concave-convex structure layer and a touch sensing layer. The display substrate includes an array substrate, a color filter substrate and a liquid crystal layer interposed between the two substrates. The color filter substrate is located above the array substrate, has a first surface facing the array substrate and a surface far away from the array substrate and connected to the first surface. the opposite second surface. The color filter substrate includes a black matrix layer arranged on the first surface. The transparent concave-convex structure layer is located on the second surface of the color filter substrate and has a first concave-convex surface. The touch sensing layer is located on the side of the color filter substrate provided with the transparent concave-convex structure layer, and the projection of the edge of the touch sensing layer on the color filter substrate is within the projection range of the black matrix layer on the color filter substrate. The touch display device has a high transmittance, which can effectively eliminate the specular reflection phenomenon of the touch sensing layer, which is beneficial to improve the display quality of the touch display device. The invention also relates to a manufacturing method of the touch display device.

Description

technical field [0001] The present invention relates to the technical field of touch display, and in particular to a touch display device and a manufacturing method thereof. Background technique [0002] The touch technologies of the existing touch display devices mainly include plug-in, one glass solution (OGS), in-cell and on-cell technologies. Since the touch screen and the display panel are set independently of each other, the plug-in touch display device has a large thickness and cannot meet the ultra-thin requirements of some handheld devices and portable devices, and has been gradually eliminated. The touch display device of OGS integrates the touch sensing layer and the protective glass and then attaches it to the display panel through optical glue. It has the advantages of high touch sensitivity and is one of the current mainstream touch technologies. The main disadvantages It is not strong enough and fragile. In Cell's touch display device integrates the touch se...
