Abstract:
A process for fabricating a face plate assembly for a flat panel evacuated display from a transparent laminar silicate glass sheet, said process comprising the steps of:providing a template having an array of mold holes open to a first major planar surface, each mold hole corresponding to a desired location and a desired shape of a spacer support structure;positioning the laminar glass sheet in contact with the first major planar surface of the template;heating the laminar glass sheet to a temperature where it becomes flowable under pressure;creating a pressure differential between an ambient pressure and a pressure within the mold holes, the pressure within the mold holes being less than that of the ambient atmosphere, the pressure differential causing glass to be displaced from the laminar glass sheet and fill each of the mold holes to form spacer support structures;removing the laminar glass sheet and attached spacer support structures from the template;coating a surface of the laminar glass sheet to which the spacer support structures are attached with a transparent layer of conductive material; anddepositing phosphor dots on the transparent layer.
