ABSTRACT:
A method for forming interelectrode spacers for flat panel display devices that employ reduced pressures, includes the steps of; forming a substrate out of an aerogel, xerogel photosensitive material (e.g., photosensitive glass, photosensitive aerogel, photosensitive xerogel); forming a pattern of openings and gas removal channels in the substrate; and then placing the substrate between a display screen and base plate of the display device. The substrate is formulated to be light weight, insulative and with a high compressive strength for resisting atmospheric loads placed on the display screen by the reduced pressure. In addition, the substrate is formulated to be easily etched, laser ablated or photochemically machined and assembled as a third member spacer structure.
