Problems solved by technology

Both the first touch electrode layer 13a and the second touch electrode layer 13b need to be coated. At present, the materials used for coating are usually transparent conductive materials such as indium tin oxide (IndiumTinOxides, ITO). After the first layer of film is coated, Etching and cleaning are required to form the first touch electrode layer 13a. After cleaning, a second layer of film is coated on the surface of the first layer of film, and the second layer of film is etched and cleaned to form the second touch electrode layer 13b, and here At least 4 illuminations are required in the process,

Description

technical field [0001] The present invention relates to the technical field of touch display, 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 type, single glass touch type (One Glass Solution, OGS), in-cell (Incell) and out-embedd (Once) and other 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. ...
