AG (Anti-Glare) Cover Glass—is a type of functional cover glass specially designed to reduce light reflection and glare through advanced surface treatment technologies such as micro-etching, matte coatings, or physical/chemical scattering structures.
The core principle is to scatter incoming light using microscopic surface roughness, which effectively lowers the surface reflectivity of the glass. As a result, AG cover glass significantly enhances display visibility and clarity, especially in environments with strong ambient lighting.
Glass: Mohs 6–7 hardness
PC/PMMA: 3H–4H pencil hardness (with coating)
| Material Type | Characteristics | Suitable Applications |
| Aluminosilicate Glass | High hardness (≈7H), high transmittance, impact resistant, and can be chemically strengthened | Premium smartphones, tablets, automotive displays (central control screens) |
| Soda-lime Glass | Requires surface coating or etching for AG function, moderate anti-glare performance | Industrial displays, public information screens |
| PC/PMMA Composite | Economical, Lightweight, impact resistant (drop resistant), needs a hard coating | Portable devices, educational tablets, medical equipment |
| Ultra-thin Flexible Glass | Bendable (curvature radius ≤5mm), can be combined with AG coatings | Foldable display devices, curved automotive displays |
VIIST supports chemical etching and matte coating spraying processes, depending on the application, often combining Anti-reflective coating and anti-fingerprinting coating.
CNC Cutting: For example, precisely cuts special shapes or holes (such as camera openings) in cover glass.
Silkscreen Printing/Back Adhesive: Prints ink patterns (for light-blocking or decorative edges) or applies OCA adhesive for full lamination of cover glass onto display modules.
