Some aspects of the gas discharges in multicolor displays are discussed. The different techniques for generating visible radiation are mentioned. It is shown that the intrinsic luminous efficiency of a gas discharge is greatly reduced in real display panels by virtue of a number of factors, which are calculated. It appears that the positive column discharge in a gas mixture of argon and mercury vapor gives the highest luminous efficiency. Means of improving the luminous efficiency are indicated. A display with positive column discharges, as used in experiments, is described. The voltage and light output of a pulsed discharge are discussed.
