Abstract:
1. A static-free light guide plate assembly, comprising: an incident plane, a bottom reflection plane, a side reflection plane and an out light plane; at least one layer of optical thin film material for increasing out light effect is positioned on the surface of the out light plane; and the bottom reflection plane is positioned on a metal back plate; which is characterized in that the static-free light guide plate assembly further comprises conductive bands which are interconnected and positioned at the side plane of the optical thin film material, non-incident portion of the incident plane, the bottom surface of the bottom reflection plane and the side reflection plane, wherein the conductive bands are positioned at the two sides of the bottom surface contacting the metal back plate and the electric charge is transferred toward the metal back plate and then neutralized; and the conductive bands are conductive tapes, conductive foams, conductive metal gauzes, sheet metals, or metal powder.
