Problems solved by technology

[0003] The traditional touch panel coating is mainly based on evaporative coating. Through single-point high-temperature evaporation, the adhesive is attached to the surface of the film and the film is further coated on the touch panel. The coating of the touch panel obtained in this way is Poor timeliness and stability, poor flatness, easy to bubble
At the same time, in the existing technology, the coated touch panel is easy to scratch during use, and if the force is too high, it may damage the panel body, which not only causes aesthetic problems, but also may cause quality problems
[0004] At the same time, when the touch panel is in use, through the tactile feedback image, the touch panel with low transmittance and high reflectivity will affect the user experience

Embodiment 1

[0031] A coating process for a glass material touch panel, comprising the following steps:

[0032] 1. Take the raw material of the touch panel with a flat surface and no air bubbles with a thickness of 5mm, cut its four sides into the size that needs to be formed, and then polish the side to keep the flatness of the side at 0.08-0.15mm to ensure the shape The flatness of each surface of the rear touch panel;

[0033] 2. Rinse the cut touch panel in running water for 5-10 minutes to remove the impurities on the surface, take it out and drain it, then immerse it in absolute ethanol for 15-20 minutes to disinfect the surface and remove the impurities on the surface of the panel and bacteria;

[0034] 3. Fix the sterilized touch panel in the coating mold, keep the upper surface of the panel flat, and reduce the error during coating;

[0035] 4. Take a TCO film with the same length and width as the touch panel and a thickness of 0.05mm. The transmittance of the TCO film is ≥ 94....

Embodiment 2

[0042] A coating process for a glass material touch panel, comprising the following steps:

Abstract

The invention discloses a coating process of a glass touch panel. The coating process comprises the following steps: cutting according to a size, disinfecting, cooling after baking, plating a nano-film, and cooling after baking to obtain the coated touch panel. Before film coating, the upper end surface of a panel is kept flat, so that errors during film coating are reduced; baking can reduce thepossibility of generating bubbles. When the touch panel is coated with a film, the touch panel is baked after being pressed, so that the panel and the film are bonded more firmly, the possibility of generating bubbles is also reduced, and the timeliness and stability of the coated touch panel are guaranteed; the touch panel is sequentially with a TCO film and the nano film, so that the compressivestrength and the scratch resistance are improved, the quality of the touch panel is protected to a certain extent, and the service lifetime is prolonged; meanwhile, the prepared coated touch panel has good transmittance and reflectivity, the transmittance is larger than 82%, the reflectivity is smaller than 2.5%, the normal use feeling is met, and the practicability is high.

Description

technical field [0001] The invention relates to the field of coating of touch panels, in particular to a coating process of glass material touch panels. Background technique [0002] The touch panel is an inductive liquid crystal display device that can receive input signals such as contacts. When the graphic button on the screen is touched, the tactile feedback system on the screen can drive various connection devices according to the pre-programmed program. It can be used for It replaces the mechanical button panel, and creates vivid audio-visual effects through the liquid crystal display screen. [0003] The traditional touch panel coating is mainly based on evaporative coating. Through single-point high-temperature evaporation, the adhesive is attached to the surface of the film and the film is further coated on the touch panel. The coating of the touch panel obtained in this way is Poor timeliness and stability, poor flatness, easy to bubble. At the same time, in the ...
