Touch display device and manufacturing method thereof

Abstract

The invention discloses a touch display device which comprises a display substrate, a transparent concave-convex structural layer and a touch sensing layer. The display substrate comprises an array substrate, a colored filtering substrate and a liquid crystal layer clamped between the array substrate and the colored filtering substrate. The colored filtering substrate is located above the array substrate and is provided with a first surface opposite to the array substrate and a second surface away from the array substrate and opposite to the first surface. The colored filtering substrate comprises a black matrix layer arranged on the first surface. The transparent concave-convex structural layer is arranged on the second surface of the colored filtering substrate and provided with a first concave-convex surface. The touch sensing layer is located on the side, provided with the transparent concave-convex structural layer, of the colored filtering substrate. The projection of the edge of the touch sensing layer on the colored filtering substrate is within the range of the projection of the black matrix layer on the colored filtering substrate. The touch display device has the high penetration rate, can effectively eliminate the specular reflection phenomenon of the touch sensing layer, and is beneficial to improving display quality. The invention further 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...

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
