Abstract

A revised image plane translator (RIPT) for a multi-pixel display is made by forming an array of subpixel position cells of refractive index n.sub.a glass frit in a binder, enclosing each cell in lower refractive index n.sub.b or n.sub.c glass frit, vitrifying the array by curing at vitrification temperature for a appropriate time, cutting the array into plates of appropriate thickness to serve as face plates, and then adding appropriate pixel controls and colorations. As a result, the face plate is inexpensive to make, robust, and of very high image quality since each pixel is a cell insulated from its neighboring cells by glass of lower refractive index n.sub.b or n.sub.c ; this traps light within the cell so that the cell can transmit the pixel without interference from its neighboring pixel position cells. There is no loss of resolution due to divergence through the thickness of the face plate. The RIPT serves as a substrate for a liquid crystal display or afield emission display, isolating high-temperature processes for semiconductor deposition and subsequent low-temperature processes for printing the pixel-defining color filters and background. This permits the use of heat-sensitive pixel defining color filters on the outer surface together with an unpatterned phosphor layer on the inner surface.
