Problems solved by technology

At present, none of the existing mass-market human-machine interface systems have antibacterial functions, which increases the route and probability of bacterial infection. At the same time, since the touch screen needs to be intensively cleaned by manual methods at regular intervals, it not only consumes a lot of manpower and material resources, but also is more likely to cause Damage to electronic information devices due to cleaning solvents used

Embodiment 1

[0025] Embodiment 1: a kind of manufacturing method with antibacterial layer touch screen, its preparation steps are:

[0026] (1) Perform anti-glare treatment on a touch screen with glass material as the panel substrate: first, disperse nano-silver particles with a particle size of 1nm-100nm in the form of 30KHz ultrasonic vibration in the alcohol In the solvent; then mix an anti-glare surface treatment liquid composed of silicate (ester) compound and alcohol solvent into the dispersion, stir it for more than 10 minutes to make the two evenly mixed, and adjust the mixing The pH value of the solution is acidic, and the concentration of the nano-silver particles is maintained at 20-500 ppm.

[0027] (2) Spray the mixed solution evenly on the surface of the touch screen cover plate by spraying, and then perform heat treatment on the surface. The heat treatment temperature is 180° C. and the heat treatment time is 45 minutes.

[0028] (3) After the solvent in the composition on ...

Abstract

The invention discloses a manufacturing method for a touch screen with an antibacterial layer, and relates to the technical field of touch screens. The manufacturing method comprises the following steps: uniformly dispersing the granules of a nano-scale metal material into a chemical liquid for surface treatment, and keeping the concentration of the chemical liquid between 20ppm to 500ppm; uniformly coating the surface of the cover plate of the touch screen with the treated chemical liquid; and carrying out heat treatment on the uniformly-coated chemical liquid, completely evaporating a solvent in the chemical liquid, and closely attaching the granules of the nano-scale metal material onto the surface of the cover plate of the touch screen, thereby forming the antibacterial layer on the cover plate. The manufacturing method disclosed by the invention is simple and practicable; and the nano-scale metal material is uniformly and firmly attached onto the surface cover plate of the touch screen, high in antibacterial capacity, capable of reducing the routes and probability of bacterial infection, time-saving and labor-saving, capable of effectively protecting an electronic informationdevice and prolonging the service life of the electronic information device, and easy to popularize and use.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a method for manufacturing a touch screen with an antibacterial layer. Background technique [0002] Touch screen, also known as touch screen, is an inductive liquid crystal display device that can receive input signals such as contacts. When touching the graphic buttons on the screen, the tactile feedback system on the screen can drive various The connecting device can be used to replace the mechanical button panel, and to create vivid audio-visual effects through the liquid crystal display screen. As the latest computer input device, touch screen is currently the simplest, most convenient and natural way of human-computer interaction. It is widely used in public information inquiry, industrial control, electronic games, multimedia teaching and other fields. At present, none of the existing mass-market human-machine interface systems have antibacterial functions, which in...
