Cover glass for LCD panel

An integral cover glass for an LCD panel having an array of microlenses integral with the outside of its front face, whereby light is focused by each microlens to enhance light output from the panel. The microlens array may be a pattern of diffractive gratings; an array of spherical shaped surfaces...

Beschreibung
Zusammenfassung:	An integral cover glass for an LCD panel having an array of microlenses integral with the outside of its front face, whereby light is focused by each microlens to enhance light output from the panel. The microlens array may be a pattern of diffractive gratings; an array of spherical shaped surfaces developed on a glass substrate; or an array of microlenses formed by ion exchange in a glass to provide a gradient refractive index in the glass.
