Compatible Color Picture Presentation with the Single Gun Tricolor Chromatron

Techniques suitable for operation of the single-gun tricolor Chromatron tube with present-day compatible color television standards are presented. The experimental circuits constructed to explore two methods of use are described, along with the results of practical testing of these circuits. A method of correcting for circuit nonlinearity which assures color balance under all situations of light level is discussed, in connection with the problem of adding color-difference information directly into the gun of the picture tube.
