AG – Anti Glare

Anti-Glare coating improves readability the of your display in sunlight conditions or environments with high ambient light. This treatment is generally used for displays intended to be used in close proximity to windows or subject to direct overhead lighting.

Think of Anti Glare as dealing with sources of external light – the aforementioned sunlight or high ambient light which impair the readability of the image a display is trying to show. Anti-glare works by roughening the surface of the display, turning specular reflection into diffuse reflection, by either etching the overlay with a solvent or other chemical, or dip coating the overlay with a solution which on drying will leave a roughened surface. This roughened overlay changes the ratio of mirror-like reflection from the surface of the display.

Benefits of Anti-Glare:

  • Low cost solution
  • Improves readability in outdoor environments

Negatives of using Anti-Glare:

  • Not a perfect solution - the diffusion method scatters light rays, which can produce around 8% reflection output.
  • This can reduce clarity and resolution of the intended image
  • Due to the roughness of the surface, anti-fingerprint film is generally also needed to combat fingerprint marks

Anti-Glare coating is a low cost method of improving display readability, but for optimal viewability, Optical Bonding the display should be considered.
