Problems solved by technology

The screen part of the resistive touch screen is a multi-layer composite film that matches the surface of the display, with a layer of glass or plexiglass as the base layer, generally called a glass substrate, and the surface of the glass substrate is coated with an AG layer. Anti-glare function, but there are generally some transparent areas around the touch screen. These transparent areas are used to display the status of some touch screens, such as displaying power status, temperature, etc. according to requirements. The glass substrate corresponding to this part of the transparent area cannot be covered by the AG layer. Coa

Example Embodiment

[0015] The present invention will be described in detail below with reference to the accompanying drawings and specific examples.

[0016] Such as figure 1 As shown, the front surface 11 of the glass substrate 1 is provided with a touch screen 111 and a transparent region 112;

[0017] A method of processing a transparent region of a glass substrate coated with an AG layer, characterized in that the following flow:

[0018] Step 1: The positive surface 11 of the glass substrate 1 is coated with an ink at the transparent region 112 of the glass substrate 1, and the ink is 1 to 3% of the curing agent;

[0019] Step 2: Baking ink, drying it; the temperature of the baking ink is 130 to 150 ° C, the length of 5 to 15 minutes is baked;

[0020] Step 3: Apply an AG layer on the front surface 11 of the glass substrate 1:

[0021] Step 4: After the wiping is cleaned, the positive surface 11 of the glass substrate 1 is cleaned by ultrasonic waves, and the AG layer above the ink and the ink is

Abstract

A processing method for a transparent area of a glass substrate coated with an AG layer comprises the following steps that firstly, the front surface of the glass substrate is printed with printing ink through a screen printing plate, the transparent area of the glass substrate is coated with the printing ink, and the printing ink is printing ink without a curing agent or printing ink with a low curing agent; 2, baking the printing ink to dry the printing ink; step 3, coating the whole front surface of the glass substrate with an AG layer; and step 4, cleaning the front surface of the glass substrate, and cleaning the ink and the AG layer above the ink to expose a transparent area. According to the invention, the characteristic that the ink without or with little curing agent is easy to clean is utilized, the process is simple, cleaning is very clean, and burrs are not left on the edge of the remaining coated AG layer after cleaning, so that the edge is neat and clear; in addition, the printing ink without or with less curing agent is convenient to clean, and the transparent area is not abraded in the cleaning process, so that the yield is greatly improved.
