Anti-glare glass cover, or AG (Anti-Glare) glass cover, is chemically etched or sprayed on the surface of the glass on one or both sides of the special treatment to achieve the effect of multi-angle diffuse reflection, reducing the reflectivity from 8% to less than 1%. This treatment changes the roughness of the glass surface, so that the surface becomes matte (uneven granular), it can reduce the interference of ambient light, improve the viewing angle and brightness of the screen, reduce screen reflections, so that the image is clearer, more colorful, more saturated colors, thus improving the display effect, thereby reducing the reflection of the light, to achieve the purpose of not blinding, so that the viewer can experience better sensory vision! In the touch screen, anti-glare is used to reduce the reflection of light, so that the viewer can experience better sensory vision.
Types of AG glass:
1. etched AG glass: etched AG glass, also known as chemically etched AG glass, is a chemical reaction to turn the glass surface from a smooth surface to a micron-level particle surface.
2. Spraying AG glass: spraying AG glass is sprayed on the glass surface with a layer of granular adhesion for high temperature baking and curing, its shortcomings are obvious: low firmness, especially the coating material in writing friction stains corrosion and other circumstances, easy to fall off, local fuzzy and other problems, which will bring about fuzzy images, inaccurate positioning, and a serious shortening of the service life. Therefore, now we basically choose to use etched AG glass.
Parameters of AG glass: The parameters of AG glass are mainly as follows:
1. Thickness
2. Transmittance: in the process of incident light passing through the glass, the proportion of light projected and transmitted through the glass to the projected light.
3. Roughness: refers to the surface of the glass AG treatment with a smaller pitch and tiny peaks and valleys composed of micro-geometric features.
4. Glossiness: the glass surface is close to the degree of mirror, the higher the gloss indicates that the glass surface is closer to the mirror.
5. Haze: Haze is a deviation from the incident light more than 2.5 ° angle of the transmitted light intensity of the total transmitted light intensity of the percentage, that is, transparent or semi-transparent materials, an important parameter of optical transparency. Higher haze means a decrease in film gloss as well as transparency and especially imaging. The cloudy or turbid appearance of the interior or surface of a transparent or semi-transparent material caused by diffuse light.
6. Particle Span: It refers to the size of the diameter of the particles on the surface of the glass after etching.
7. Clarity: AG glass glass clarity is generally related to the particle span indicator, the smaller the particles, the lower the span, the greater the pixel density value, the higher the clarity.
In the touch screen, the specific role of anti-glare glass cover is mainly reflected in the following aspects:
1. Improve the viewing angle: anti-glare glass cover can reduce the interference of ambient light, reduce screen reflections, thus expanding the viewing angle of the screen, so that users can clearly see the screen content at different angles.
2. Protect your eyes: Because the anti-glare glass cover has a diffuse reflection effect, it can effectively reduce the glare caused by screen reflections, reduce eye irritation, and protect the user's eyesight. Especially in the case of prolonged use of the touch screen, this protective effect is particularly obvious.
3. Enhance the user experience: anti-glare glass cover not only improves the visibility of the screen and eye comfort, but also provides a more delicate touch through its matte surface texture, enhancing the overall user experience.
In addition, the anti-glare glass cover has significant advantages in specific application scenarios. For example, in outdoor bright light environments, such as ATMs, charging piles, gas stations and other equipment, anti-glare glass cover can effectively reduce the direct reflection of sunlight and improve the clarity of the screen; in indoor bright light environments or scenes that require a long period of time to look at the screen, such as monitors in the operating room, POS, e-reading books, learning machines, etc., the anti-glare glass cover can also play an important role in alleviating visual fatigue and protecting the eyes. and protect the eyes.
In summary, the application of anti-glare glass cover in touch panel not only improves the visibility of the screen and the visual comfort of the user, but also enhances the user's overall experience through its high quality touch and significant advantages in specific scenarios.
