Problems solved by technology

However, the large-scale process involves cutting and CNC processing after glass tempering, which destroys the structure of the OGS glass tempered layer, and forms numerous small cracks within a depth of 0.15mm from the cutting section to the glass surface. These small cracks reduce the quality of the OGS glass. The stress value of the surface reduces the overall strength of the OGS structure touch screen
Although it is repaired by increasing the process of chemical strengthening, the uniformity of product strength is poor, which affects the overall quality

Embodiment 1

[0020] Example 1: OGS glass shape processing method, the steps are as follows:

[0021] 1) The large sheet of glass is 550mm×450mm×0.7mm, and 8×5 (8 horizontally, 5 vertically) acid-resistant protective films are printed on the front and back through typesetting. There is a one-to-one correspondence between the top and bottom of the acid-resistant protective film. The shape of the acid-resistant protective film is the same as that of the finished OGS glass, and its size is 0.15mm larger than that on one side.

[0022] 2) Soak a large piece of glass in cyanofluoric acid solution and perform equal etching. The concentration of cyanofluoric acid is 20% (volume percentage), the time is 130min, the temperature is 40°C, and the etching depth is 0.15mm. The large glass after etching is called the substrate , so that the front and back sides of the substrate form grooves around the periphery of the OGS glass-shaped acid-resistant protective film.

Embodiment 2

[0027] Example 2: OGS glass shape processing method, the steps are as follows:

[0028] 1) The large sheet of glass is 500mm×450mm×0.7mm, and 7×4 (7 horizontal and 4 vertical) acid-resistant protective films are printed on the front and back through typesetting. There is a one-to-one correspondence between the top and bottom of the acid-resistant protective film. The shape of the acid-resistant protective film is the same as that of the OGS glass product, and its size is 0.14mm larger than that on one side.

[0029] 2) Soak a large piece of glass in cyanofluoric acid solution and perform equal etching. The concentration of cyanofluoric acid is 10% (volume percentage), the time is 140min, the temperature is 38°C, and the etching depth is 0.14mm. The large glass after etching is called the substrate , so that the front and back sides of the substrate form grooves around the periphery of the OGS glass-shaped acid-resistant protective film.

Abstract

The invention discloses a contour machining method of OGS (One Glass Solution) glass. The method comprises the following steps: printing acid-proof protective films on both surfaces of a big piece of glass, wherein the contour of each acid-proof protective film is similar to that of the OGS glass; equivalently etching non-protective areas by using cyanide fluorhydric acid, thereby forming a base plate; tempering the base plate, thereby forming a uniform tempered layer on the surface of the base plate, wherein the tempered base plate is called as a parent plate; carrying out a plurality of film coating and yellow light machining treatments on the parent plate, thereby forming an ink layer and a TTO (Indium Tin Oxide) line layer on the non-etching area of one surface of the parent plate, wherein the parent plate with the ink layer and the TTO layer is called as a functional slice; removing waste materials from a groove in the parent plate in a cutting manner, thereby forming a monolithic OGS glass semi-finished product; and finally, grinding a cutting surface by using CNC (Computerized Numerical Control Machine), thereby forming an OGS glass finished product. According to the invention, the integrity of the tempered layer of the surface of the OGS glass is guaranteed essentially, so that the functions of the stress layer of the surface of the OGS glass are guaranteed. Therefore, the overall strength and bulk strength of OGS capacitive touch screens are guaranteed.

Description

technical field [0001] The invention relates to a capacitive touch screen with OGS (One glass solution) structure, in particular to a cutting method of OGS glass. Background technique [0002] At present, the mainstream capacitive screen on the market is composed of cover glass, ITO (indium tin oxide) transparent sensor, flexible circuit board, control chip IC (control integrated chip), OCA (optical transparent adhesive), protective film, electronic components, the overall thickness More than 0.9mm, the light transmittance is less than 86%. The OGS structure capacitive screen realizes the integration of cover glass and touch screen, that is, OGS glass. Eliminating the ITO transparent sensor, OCA, and multiple bonding processes, the cost of the touch screen is reduced by about 30%, the overall thickness is controlled within 0.7mm, and the light transmittance is greater than 90%. Compared with the current mainstream capacitive screen, OGS capacitive screen is thinner, has h...
