MULTICOLOR GAS DISCHARGE DISPLAY MEMORY PANEL Abstract of the Disclosure Gas display panel performance with improved resolution, color, memory margin and brightness is provided as a result of helium based mixtures in a panel structure using evaporated glass tech- nology, e.g., borosilicate glass technology. Multicolor emissions are achieved directly from the helium based mixtures, and addition- al color enhancement and selection is accomplished by varying the gas parameters of pressure and dopant concentration and the sustain voltage waveform drive conditions. Color selection from the helium based mixtures with molecular dopants is made using an optical fil- ter or a colored glass substrate. A gas panel is obtained that emits white light using a helium based mixture doped with oxygen. It is a Penning mixture with optical radiation in the visible part of the spectrum due to systems of emission bands from the ionized oxygen molecules. The first negative system exhibits four strong bands that vary from 75 to 125.ANG. in width and account for green, yellow and red colors. In addition, four weaker bands are observed for the second negative system which account for the blue color.
