Elimination of disturbing light reflections (non-glare)

A non-glare surface treatment minimises the reflection of light from the display window surface. Untreated acrylic surfaces typically reflect 8% of incoming light. Generally speaking, reflections of more than 4% of the incoming light is disturbing to the human eye. The purpose of a non-glare surface treatment is therefore to minimise disturbing light in order to improve e.g. sunlight readability and contrast of the display.

As the figure to the right illustrates, the light from the sun hits the display window and with a surface treatment, a smaller part of this light is reflected. 

Abrasion resistance

A hard surface is more resistant to abrasions or scratches than a soft surface. On plastic surfaces the hardness is measured as "pencil hardness". This is a test method determining the hardness of an organic surface through moving pencil leads of known hardness grade over the surface tested at a fixed angle and pressure.

Untreated acrylic and polycarbonate materials have a pencil hardness of approximately one. With a surface treatment, the pencil hardness can be improved times six.

Endless Combination possibilities

Many of PSC's surface treatments combine both (and other) features to the surface. Furthermore the surface treatments can often be applied either one-sided or on both sides of the display window.
