Problems solved by technology

During the secondary strengthening process, the treatment of the edge with hydrofluoric acid is likely to cause the surrounding surface to be corroded by hydrofluoric acid, resulting in defects, and despite the addition of the secondary strengthening process, the stress layer and stress value at the edge of the OGS glass are missing, resulting in the edge being prone to damage. The major defect of damage still cannot be overcome, which makes the yield rate of the OGS touch screen production line not high, which has caused many production companies to suffer serious losses so far

Embodiment 1

[0014] A method for improving the yield rate of touch screens produced by OGS on a large-scale production line, comprising the following steps:

[0015] 1) Use the large-size OGS touch screen production line to coat the surface of large-size ultra-thin glass with IT0 circuit film to form a large-size OGS touch glass substrate;

[0016] 2) Cut the large size OGS touch glass substrate into the required small size OGS touch glass;

[0017] 3) Pre-laminate the small-sized OGS touch glass with the six-sided tempered glass by using solid ultraviolet flexible glue, the thickness of the solid ultraviolet flexible glue is 100-120 μm;

[0018] 4) Put the pre-laminated small-sized OGS touch glass and six-sided tempered glass prepared in step 3 into the autoclave for degassing for 10-250 minutes, control the pressure in the autoclave to 0.5kg-3kg, and the temperature to 30-40°C , forming a transparent glue;

[0019] 5) Use a high-power UV lamp to irradiate the transparent glued body wit...

Embodiment 2-3

[0021] The same preparation method as in Example 1 was adopted, except that the thickness, pressure and temperature listed in Table 1 in the pre-lamination and defoaming steps were used instead of the corresponding values ​​used in Example 1.

[0022] Table 1

[0023]

[0024] The finished product obtained by the embodiment of the present invention 1-3, each group of physical detection data is as shown in Table 2 (wherein, the control group 1-3 in Table 2 is the finished product obtained by adopting the original OGS glass production process):

[0025] Table 2

[0026]

[0027] It can be seen from Table 2 that the edge strength of the glass of the finished product obtained in Examples 1-3 of the present invention is stronger than that of the control group, and the result of the falling ball impact test is also better than that of the control group. The new OGS touch screen produced by the technical solution of the present invention utilizes an impact-resistant transparen...

Abstract

The invention discloses a method for increasing the finished product rate of OGS touch screens produced on a large-size production line. According to the method, an impact resistant transparent substrate is attached to OGS touch glass through solid-state ultraviolet flexible glue to form sandwich type laminated safety glass, an original OGS touch screen which is broken and damaged easily is changed into the novel OGS touch glass which is resistant to impact and dropping, safe, environmentally friendly and low in cost, and the problem that the finished product rate of the OGS touch screens on the large-size production line is low is solved.

Description

technical field [0001] The invention relates to a touch screen preparation process, in particular to a method for improving the yield of OGS touch screens in a large-size production line. Background technique [0002] OGS touch screen is a kind of electronic product protection screen made by the technology of directly forming ITO conductive film and sensor on the protective glass. Compared with the GG (Glass-Glass) structure, it saves the cost of a layer of glass and reduces the cost of one-time lamination. It not only reduces the weight but also increases the light transmittance. In order to reduce the production cost of OGS touch screens and increase production capacity, some OGS touch screen manufacturers have invested heavily in continuous production lines, first coating IT0 conductive film on large-sized strengthened protective glass and forming many independent sensors through subsequent etching process , and then separate these independent sensors by cutting. The st...
