Anti-glare treatment microscopically diffuses reflected light so mirror-like reflections are less distracting. It can improve practical readability, but excessive diffusion may reduce contrast, add sparkle or soften fine text.
Parameters to compare
- Haze and gloss measured using a stated method.
- Sparkle with the target pixel density and viewing distance.
- Image sharpness, black level and apparent contrast.
- Fingerprint visibility, cleaning resistance and coating durability.
- Touch sensitivity through the complete cover stack.
Sample evaluation
- Use the actual LCD, cover and bonding construction.
- Display fine text, gray scales, solid colors and dark UI screens.
- Test under diffuse office light and directional bright light.
- Evaluate normal and oblique viewing positions.
- Check wet, glove and cleaning requirements.
- Approve a controlled surface specification, not only AG.
Anti-reflection treatment works differently by reducing reflected intensity through optical coatings. AG and AR may be combined, but durability, cost and appearance must be qualified.
Compare the blur diagnosis guide, bonding materials and touch solutions.
