Problems solved by technology

[0003] Existing touch panels generally use AG glass, which is also called anti-reflection glass and anti-glare glass, so that the touch panel can achieve the effect of backlight, but the light transmittance of AG glass is still relatively high, which makes users feel dazzling and discomfort, for this reason, it is necessary to find a method that can reduce the light transmittance of the touch panel, so that the light transmittance of the touch panel can make people feel comfortable and meet the basic light quantity requirements

specific Embodiment

[0016] The following steps are required to control the final light transmittance of the product at about 10%:

[0017] Etching the glass surface: Etching the surface of both sides of the smooth glass with hydrofluoric acid, so that the structure of the glass surface changes, from the previous bright side to the foggy side, and at the same time, the light transmittance of the glass decreases from the previous 90% of that is reduced to 15% to 20%, and the etched surface has a tactile feel, and its roughness: 0.7 μm to 1.0 μm, suitable for touch control by human hands;

[0018] Adjust the printing ink: calculate the internal composition ratio of the printing ink black ink: varnish = 3:2, after mixing in proportion, the original black ink becomes semi-transparent through the dilution of varnish, and the ink performance remains unchanged;

[0019] Product printing: Use the 420# screen to print the product. After testing, if you use a screen with a larger mesh, there will be a scree...

Abstract

The invention provides a method for back surface light guiding of AG (anti-glare) glass to ensure that when the AG glass is used as a touchpad, the light transmittance of the AG glass can make people feel comfortable and can meet basic requirements of quantity of light. The method is characterized in that a semitransparent printing ink is printed on the back surface of the AG glass by virtue of a silk screen, so that the light transmittance of the AG glass is reduced.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a method for guiding light on the back of an AG glass. Background technique [0002] With the gradual popularization of existing notebook computers, notebook touch panels have gradually evolved from full-shading touch panels in the early stage to touch controls with backlight effects. At the same time, the design of the touchpad also overturned the original full-shading printing effect, and gradually evolved into a semi-shading printing effect, so that the light from the backlight can be transmitted to the user's eyes through the touchpad. [0003] Existing touch panels generally use AG glass, which is also called anti-reflection glass and anti-glare glass, so that the touch panel can achieve the effect of backlight, but the light transmittance of AG glass is still relatively high, which makes users feel dazzling and discomfort, for this reason, it is necessary to find ...
