Abstract
Walls for a flat panel display and a method for forming walls for a flat panel display that have improved thermal conductivity and decreased thermal coefficient of resistivity. In one embodiment, walls are fabricated using alumina, molybdenum, and titania. These oxide materials (alumina and titania) are mixed with the a metal oxide and cast so as to form thin sheets of material that are then heated. The heating process reduces the metal oxides to their metallic state. The resulting thin sheets of material are then cut to form walls. This produces walls having a higher thermal conductivity than prior art walls. In addition, the thermal coefficient of resistivity of the resulting material is significantly lower than that of prior art materials used for making walls. A flat panel display having the walls of the present invention does not exhibit non-illuminated regions of the visible display due to wall-related thermal effects.
