Anti-glare treatment
Anti-glare treatment is a treatment of the display surface that reduces distracting reflections from lamps, windows and sunlight.
There are two basic types: a matte surface that scatters light, and an optical coating that cancels reflections. Both improve legibility in bright surroundings.
In a shop, in a foyer with a glass front or behind a shop window, reflections often decide legibility more than brightness. A display with a glossy surface shows vivid colours but reflects its surroundings. Matte surfaces are common on signage displays because they spread light sources into a diffuse sheen.
Operators should note that additional protective glass in front of the display creates new reflections, including between the glass and the picture area. Anti-reflective glass or optical bonding, in which the air gap between glass and panel is filled, helps here. A matte surface can make the picture look slightly softer. No treatment on the display helps against reflections in a shop window pane; only placement and distance do.
