Vacuum fluorescent display panel with integral illumination of panel indicia

摘要

An improved vacuum fluorescent (VF) display panel includes a VF display device having an integral VF light source that is shielded from viewer of the display, and that provides illumination for panel indicia formed in the vicinity of the VF display. The integral light source for indicia illumination is produced at one or more marginal areas of the VF display by secondary anode segments and an integral reflector structure that directs the light produced by the secondary anode segment(s) laterally through a transparent side glass of the display housing. A light-pipe structure adjacent the VF display receives the laterally directed light, and uses the received light to illuminate the panel indicia.
