Abstract
Abstract THERE IS DISCLOSED A PROCESS FOR EMBEDDING PHOSPHOR PARTICLES IN THE SURFACE OF AT LEAST ONE DIELECTRIC MEMBER TO BE ASSEMBLED IN A MULTIPLE GASEOUS DISCHARGE DISPLAY/ MEMORY PANEL SUCH THAT THE PHOSPHOR PARTICLES ARE PARTIALLY EXPOSED TO THE GASEOUS MEDIUM OF THE ASSEMBLED PANEL AND ARE CAPABLE OF BEING EXCITED BY RADIATION FROM THE GASEOUS DISCHARGES OF SUCH ASSEMBLED PANEL. ANY SUITABLE LUMINESCENT PHOSPHOR WHICH IS COMPATIBLE WITH THE DIELECTRIC MAY BE USED; HOWEVER, PHOTOLUMINESCENT PHOSPHORS ARE HIGHLY PREFERRED. ONE EMBODIMENT COMPRISES PARTIALLY EMBEDDING THE PHOSPHOR PARTICLES BY MEANS OF A PHOTOSENSITIVE MATERIAL.
