1. A liquid crystal display comprising:
- a backlight assembly;
a reflector positioned against the backlight assembly; and
a protective film covering at least a portion of a surface of the reflector opposite the backlight assembly, wherein the protective film comprises a plurality of raised protrusions formed on a surface of the protective film contacting the reflector, wherein the raised protrusions comprise the same material as the protective film, and wherein the plurality of raised protrusions are operable to separate the reflector from a non-raised portion of the surface of the protective film.

Abstract
The patterning of objects (e.g., protective poly-films, heat-spreaders, and other components placed proximate to the backlight of an LCD) with multiple beads or raised protrusions is disclosed. The beads or protrusions can have a uniform or non-uniform size and can be arranged such that they have a uniform or non-uniform pattern density. The beads or protrusions can be patterned on a surface of the object to provide separation between a non-raised surface of the object and a surface of an adjacent item, such as a reflector film.
