In the era of touch-screen information, more and more places use display devices, and gradually integrate more application functions on the display screen, from large-scale combined screen walls such as aerospace measurement and control center and TV station broadcast center, to the family, Display equipment such as banks and hospital clinics, as small as personal wearable devices. The glass for display screens is also gradually replaced by anti-glare (AG) glass with anti-reflection and anti-glare functions from ordinary smooth glass, and is increasingly widely used and recognized for its excellent performance.
As we all know, the glossy glass is the smooth and flat surface of the glass. Therefore, after the light illuminates the surface, the three forms of transmission, refraction and reflection exist simultaneously. The higher the surface finish of the glass, the more obvious the reflection effect. If a single light is emitted, the retina is projected into the eye. Partial spots cause dizziness, which is the so-called glare effect, which greatly affects and reduces visual comfort, and causes certain damage to the eyes; if the ambient light is strong, it will cause so-called ghosting and ghosting on the screen surface. That is, after the ambient light brightness is higher than the screen light, the ambient image reflected by the mirror effect on the inner and outer surfaces of the screen causes the screen output image to be superimposed on the environment image, which seriously reduces the output image quality of the screen itself and interferes with the viewing quality. Reflective environmental images are mainly used on the surface of the screen using a glossy glass substrate.
Anti-glare glass, AG glass, is a nano-scale roughening treatment of one side of the glossy glass by physical or chemical methods to diffuse the incident light, reduce the intensity of reflected light at a single angle, eliminate the glare effect and specular reflection effect, and improve the outside world. The interference of light on the screen image ensures the quality of the image clarity, and also reduces the damage of the glare to the retina of the eye.
Through the anti-glare technology on the screen surface, the surface reflectance is reduced to less than 1%, which basically eliminates the influence of the reflected light from the outer surface, greatly reduces the influence of reducing the glare and reflection of the screen, and greatly improves the visual comfort of the controller. AG glass can meet the requirements of most screen display equipment.
However, the anti-glare treatment of the screen glass does not completely eliminate the interference of the environmental image on the screen. Since the reflection problem on the outer surface of the screen is eliminated, the influence of the reflected light on the inner surface is prominent, which is the inadequacy of the single-sided anti-glare glass. . In some specific environments, such as bright lighting monitoring room, but there will still be weak phantom phenomenon affecting the clarity of the screen and the accuracy of interference observation. Especially in the urban traffic video control center, aerospace flight control center, precision product design center and hospital large-scale medical equipment room, etc., the operator needs to quickly browse and accurately analyze and judge the screen image, if caused by virtual shadow interference. The judgment error is serious.
Therefore, completely solving the phenomenon of screen ghosting is the expectation of users in many special fields for the anti-glare glass industry, and also the need for anti-glare glass technology.
The double-sided anti-glare glass simultaneously performs nano-level roughening treatment on the inner and outer surfaces of the screen glass, so that the incident light is diffusely reflected at both the inner and outer surfaces of the glass, and at the same time, the intensity of the single-angle reflected light of the inner and outer surfaces is reduced, and the glare effect and the specular reflection are substantially eliminated. The effect is to eliminate the interference of external light on the screen image, completely guarantee the image clarity viewing quality, and eliminate the damage of glare to the retina of the eye.
