Embodiment Construction

[0032] A resistive glass / glass touch screen as shown in Figure 1 to Figure 3, its manufacturing process is: after the upper and lower glass substrates of the touch screen are bonded and sealed, they are soaked in a groove filled with etching solution for etching, and the glass substrate A certain thickness is formed after etching. The specific production steps are as follows:

[0033] A. Etch a pattern on the transparent conductive layer 2b of the lower glass substrate 2 and make scattered isolation points 4, and then make electrodes 7, 8, 9, 10 on the top, and the thickness d2 of the electrodes is 8-25 microns.

[0034] B. Make an adhesive 3 on the lower glass substrate 2. The adhesive can be heat-cured epoxy resin, which is mixed with rod-shaped or spherical particles with a diameter between 5 microns and 20 microns. The main function of the mixed rod-shaped or spherical particles is Determine the distance d between the edges of the upper and lower glass substrates;

Abstract

The invention discloses a making method of resistance-typed glass / glass typed touching screen, which comprises the following steps: etching pattern on the transparent conductive layer of lower glass base to make dispersing separating point; making electrode and binder on the lower glass base; etching pattern on the transparent conductive layer of upper glass base to make electrode thereon; binding upper and lower glass bases; sealing the rim; using etching liquid to etch to the needed depth; cutting two pieces of glass base according to the size of touching screen; obtaining the product. The invention has high reliability, simple technique and low cost, which can prevent glass from cracking.

Description

technical field [0001] The invention relates to a method for manufacturing a touch screen, in particular to a method for manufacturing a resistive glass / glass type touch screen. Background technique [0002] Currently, as an input technology, resistive touch screens are more and more widely used. The resistive touch screen can be divided into: film / film, film / glass, glass / glass and other types. Among these three types of touch screens, the glass / glass type touch screen has the highest reliability and is the main force used in military, vehicle and other fields. [0003] At this stage, in the manufacturing process of glass / glass type touch screen, because glass / glass type touch screen requires the thickness of the upper glass substrate to be small enough (≤0.2mm), under this thickness, all the processing of the upper glass substrate will encounter Great difficulties, such as: broken glass, etc. In this case, the yield rate of glass / glass type production is very low and the...
