Problems solved by technology

[0014] from image 3 It can be seen from the process flow chart that there are many and repeated processes, and poor management and control will easily lead to defective products or batch scrapping. At this stage, people in the industry who produce touch screens are said to have a good product rate of 75-85%. It is a very high leve

Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043] A new manufacturing process of touch screen, such as Figure 4 ,

[0044] Including the following steps:

[0045] Step 1, choose PET and glass, surface treatment: choose PET polyester sheet and glass substrate; then do hard coating on PET, do silica coating on glass, in order to be suitable for the surface before the transparent conductive layer Prepare;

[0046] Step 2, screen printing transparent conductive ink: then use a fine screen printing machine to print the transparent conductive ink on the above-mentioned PET and glass after surface treatment;

[0047] Step 3, curing: the corresponding PET material is baked at 130 degrees for 40 minutes, and the glass material is baked at 150 degrees for 30 minutes, and the two materials are cured respectively;

[0048] Step 4, screen printing silver paste: then add the cured PET and glass to the si...

Abstract

The invention relates to a novel manufacturing process of a touch screen, comprising the following steps: 1. selecting PET and glass, and carrying out surface treatment, i.e. selecting a PET polyester sheet and a glass substrate, making a hard coating or a hard coat on the PET, and making a silica coating on the glass to suitably prepare for making a transparent conductive layer; 2. carrying out screen printing on transparent conductive ink; 3. curing; 4. carrying out screen printing on silver paste; 5. carrying out screen printing on insulating oil; 6. carrying out screen printing and rubberizing; and 7. pasting, detecting and obtaining the finished product, i.e. pasting the PET material after screen printing and rubberizing with the semi-finished glass to obtain the finished touch screen, testing whether the linearity of the touch screen complies with the standard by utilizing a linearity tester, and finally delivering the finished product after passing the test. The novel manufacturing process of the touch screen has simple manufacturing process and high value in efficiency, cost and process.

Description

technical field [0001] The invention relates to the production field of touch screens or touch panels, in particular to a new manufacturing process for touch screens that saves energy, saves time, and improves production efficiency by replacing traditional old processes. Background technique [0002] At present, the touch screen is widely used in the man-machine interface operations of electronic and electrical products such as mobile phones, computers, GPS navigators, and machinery and equipment in recent years. It improves the convenience for us to use electronics and equipment. The structure of the touch screen is generally as follows: figure 1 It shows that when the touch screen is working, the upper and lower conductor layers are equivalent to a resistance network. When a voltage is applied to a certain layer of electrodes, a voltage gradient will be formed on the network. Another layer of voltage can measure the voltage at the contact point, so as to know the coordinat...
