Etched glass

Overview

Etched glass is one of two popular treatments for the glass surface of a pen display. The other is called an anti-glare film.

"Etched glass" describes a microscopic texture applied to a glass surface.

Etched glass provides two benefits:

• It reduces glare and reflections caused by light hitting the tablet. Etched glass does this by scattering that light.

• It provides more "grip" for the pen. Without the etching, a pen would feel "slippery" on the smooth glass surface.

Sparkle

Like other anti-glare treatments, etched glass can produce an effect called anti-glare sparkle, which is a "rainbow noise" effect. Depending on the tablet, there will be a little or a lot of this sparkle. Learn more here: Anti-glare sparkle.

Permanence

Etched glass is a permanent treatment to the glass. It cannot be removed.
