Optical Bonding reduces the amount of reflection between the glass and LCD cell as well as the reflection of external ambient light. Doing this helps provide a clearer image with an increased contrast ratio, or the difference in the light intensity of the brightest white pixel color and darkest black pixel color.

Anti-Reflective (AR) technology primarily works by reducing the reflection of light on the surface of the cover glass, thereby enhancing light transmission and improving display performance;

Anti-Glare (AG) technology is designed to diffuse light that hits the surface of the cover glass, reducing the intensity of reflected light and thus minimizing glare. This results in a display that is easier to view under various lighting conditions, including bright sunlight.
