Next, we will briefly introduce the difference between AR glass and AG glass, and explain the unique advantages of AR and AG glass.
AG Glass
Name: anti-glare glass
AG Glass Definition:
AG anti-glare glass (Anti-GlareGlass) products are made through a special chemical process, which is characterized by changing the reflective surface of the original glass into a matte diffuse reflective surface. It can blur the effect of reflection, prevent glare and reduce the degree of reflection, reduce light and shadow, and the surface of anti-glare products has strong anti-corrosion and anti-scratch performance.

Combined with the video imaging screen, it can form a transparent anti-glare and anti-reflection screen, which solves the problems of reflection and glare caused by electronic video screens and video screens under ambient light sources, and improves the image quality. This effect does not change at large viewing angles.
Function and case
Function: When the external light is reflected, it will form diffuse reflection, thereby reducing the reflection of light, achieving the purpose of not dazzling, so that viewers can experience better sensory vision. The lower the glossiness, the better the diffuse effect of its surface, and the less affected by external glare. AG glass has single-sided and double-sided, and the AG-treated side must be on the top when used.
Application cases: Outdoor digital signage displays or displays under strong light are mostly used. Such as advertising displays, ATM cash machines, POS cash registers, medical B-ultrasound displays, e-book readers, gas station displays, subway ticket inspection machines, etc.
Simple identification method: put a piece of glass under a fluorescent lamp, and observe the lamp tube from the front of the glass. If the light source of the lamp tube is dispersed, it is an AG-treated surface, and if the light source of the lamp tube is clearly visible, it is a non-AG surface. This is the most direct way to tell from the visual effect.
AR Glass
Name: Anti-reflection glass
AR Glass Definition:
By optically coating one or both sides of the glass to reduce its reflectivity and increase its transmittance. The maximum value can increase its transmittance to more than 99%, and control its reflectance to less than 1%.
Function and case
Function: By increasing the transmittance of the glass, the content of the display can be displayed more clearly.
Application cases: high-definition displays, photo frames, mobile phones, and cameras of various instruments.
Simple identification method: Take a piece of ordinary glass and a piece of AR glass, and stick them side by side to the computer or other paper screens at the same time. The clearer effect is the AR glass.
Features:
1. Visible light transmittance can reach 99%
The average transmittance of visible light exceeds 95%, greatly improving the original brightness of LCD and PDP, and reducing energy consumption.
2. The average reflectance is lower than 4%
Effectively weaken the defect of whitening the picture caused by strong light behind, and enjoy a clearer image quality.
3. More vivid colors and stronger contrast
Make the image color contrast stronger and the scene clearer.
4. Anti-ultraviolet rays, effectively protect the eyes
The transmittance in the ultraviolet spectral region is greatly reduced, which can effectively prevent the damage of ultraviolet rays to the eyes.
5. High-temperature resistance
AR glass temperature resistance > 500 degrees (normal acrylic can only withstand a temperature of 80 degrees)
6. Good scratch resistance and wear resistance
The hardness of the AR glass film layer is equivalent to that of glass, greater than 7H, (the hardness of the general PC board is about 2H to 3H).
7. Resistant to various cleaning agents
It is resistant to acid and alkali cleaning agents and the film layer will not be damaged.
8. Strong impact resistance
The impact performance of 3mm thick glass is equivalent to 6mm acrylic.
9. Keep perspective
Generally, after acrylic is installed, the viewing angle will become smaller; but after AR glass is installed, the viewing angle will not become smaller.
10. Appearance
The surface flatness of AR glass is much better than that of coated acrylic, and the larger the size, the more obvious the difference.
11. The cold and heat deformation of AR glass is almost negligible, and it is suitable for various environments; at the same time, AR glass has a glazed feel and a more beautiful appearance.
Different performance
AG glass, the full name anti-glare glass, also call as non-glare glass, is used to reduce strong light reflections or direct fire. Therefore, in terms of optical parameters, AR glass has more functions to increase light transmission than AG glass.
