Problems solved by technology

The electrode that can be produced by printing low-temperature silver paste has low resolution and low yield rate; the electroless plating method generally uses gold (Au), which not only has many processing steps, but also has poor adhesion of Au, and the cost of Au is very high. High, low production yield
If the glass substrate is too thick, it will increase the weight, if it is too thin, it will be easily damaged during the production process, and it cannot be curled, and the production efficiency is low
[0006] At present, there are many structural layers in the separate touch display device, which makes it difficult to further thin it. After the touch panel and the display panel are produced separately, the production cost is high, and the process is complicated, requiring later assembly, the process is difficult to control, and the production efficiency is low.

Embodiment 1

[0049] The roll-type polyethylene terephthalate (PET) film is selected as the base material, and an indium tin oxide (ITO) layer 2 and a copper (Cu) layer are successively plated on the upper surface of the PET film 1 by vacuum sputtering coating method 8, and then successively plate indium tin oxide (ITO) layer 5 and copper (Cu) layer 8 on the lower surface by vacuum sputtering coating method, see image 3 ; Make photosensitive adhesive layer 11 and layer 12 successively with the mode of screen printing on both sides, refer to Figure 4 , and then expose, develop, etch, and remove glue at one time, and make transparent electrode patterns and wiring strengthening patterns at the same time, see Figure 5 , 6, 7; then make protective adhesive layer 4 and layer 7 by screen printing in the area where the wiring is strengthened, see Figure 8 ; This protective glue needs to be able to withstand the immersion of the secondary etching solution; then, perform a second round of second...

Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is that the base material used for sensor production is not only PET, but also glass, or PC, or PMMA, or polyolefin, or flexible materials.

Embodiment 3

[0053] The difference between this embodiment and Embodiment 1 is that, in addition to using the method of vacuum sputtering coating to make the transparent conductive layer, it can also be made by vacuum ion coating, vacuum thermal evaporation coating or coating. The transparent conductive layer can be indium tin oxide (ITO), zinc oxide (ZnO), tin oxide (SnO), aluminum (Al), nickel (Ni), molybdenum (Mo), gold (Au), silver (Ag), copper (Cu), carbon nanotube (CNT) film or conductive resin or any combination of several.

Abstract

The invention provides an integrated touch display device and a making method thereof. The integrated touch display device comprises a glass panel, a polarizer, a sensor and a liquid crystal display. The making method of the touch display device comprises the steps of plating a transparent conductive layer and a metal reinforcing layer on both faces of a base material in sequence by using a vacuum sputtering film plating method; and then making designed electrode patterns on the transparent conductive layer and the metal reinforcing layer by using a photo-etching method; next, making a layer of protective adhesives on a lead region of the metal reinforcing layer; carrying out second metal etching so as to remove the metal reinforcing layer of a non-lead region; plating silicon dioxide layers on the both faces of the base material to finish the making of the sensor; and finally combining the glass panel, the polarizer, the sensor and the liquid crystal display to lead out the electrode. Compared with a traditional process, the method provided by the invention has the advantages of realizing integration, thinning and light weight of the touch display panel, reducing the machining procedures, largely improving the machining efficiency and obtaining low manufacturing cost.

Description
