2.Optical parameters and relationship of anti glare glass
The main factors affecting the anti glare effect of glass are transmissivity, reflectivity, surface roughness, glossiness and haze. The relationship between them is shown in figure 4.
Figure 4 anti glare optical parameter relationship diagram
Gloss: mainly to measure the AG effect, general gloss range from 20-110%.
Haze: mainly to measure the effect of AG fog, and gloss in a certain sense inversely proportional.
Surface roughness: a measure of the roughness of the diffuse reflection point on the surface of AG glass, generally 0.06-0.25um.
(1) the glossiness is inversely proportional to the haze; the higher the glossiness, the lower the haze; the glossiness is directly proportional to the clarity; the higher the glossiness is, the higher the clarity is.
Figure 5 Relationship between glossiness, haze and clarity
(2) glossiness is inversely proportional to roughness. The lower the glossiness, the higher the roughness of the same piece of glass. The rougher the surface, the more the diffusion of light. Reducing gloss and increasing roughness can reduce the flash point of light. Of course, that doesn't mean that improving the roughness will reduce the flash point, and the flash point will come from other causes.
(3) the glossiness is proportional to the flash point. The lower the gloss, the lower the flash point. When the size of the particle matches the pixel of the display, the higher the roughness, the more rough the surface can increase the diffusion of light, the less the flash point. The next generation of display will require more and more resolution, and the flash point will be paid more attention to.
