| antiglare treatment
The glass face of a monitor has a
natural tendency to reflect light, which can be hard on the eyes and can
make it difficult to see what's being displayed. An antiglare treatment is
a coating on the glass that either absorbs or diffuses the light to
prevent reflections. Three
types of antiglare treatments are in general use. Most common is a
silica-based coating that diffuses light, which tends to decrease the
screen's focus. Another approach, using optical lenses, is better because
the lenses don't diffuse light. The third technique, mechanical etching
(that is, roughing up the surface of the glass), should be avoided because
it blurs the onscreen image. |
