Vacuum fluorescent display having integral backlit graphic patterns

摘要

A vacuum fluorescent (VF) display having integral graphic patterns backlit by an alternate light source to produce emissive graphic images in substantially the same plane as the VF graphic patterns. The backlit graphic patterns are defined by patterned openings in the anode insulation layer of a conventional VF display, and color of the backlit graphic images is determined by the color of the alternate source light, independent of the color of the light emitted from the VF phosphor.
