Abstract
A method for enhancing the luminance and uniformity of a flat panel light source provides a patterned reflective structure to reflect or deflect the light back onto the display area of a field emission display panel and lighten the area which used to be blocked by spacers. The patterned reflective structure may be designed in several places, such as between an end surface of a spacer and the inner surface of an anode substrate, or on the inner surface of the edges of the side-frame between the anode plate and the cathode plate by further coating a reflective material, or on the side-frames surrounding the panel by further coating a reflective material, etc. With such a patterned reflective structure, the luminance and uniformity of a flat panel light source are enhanced.
