An Analysis of the Necessary Decoder Corrections for Color Receiver Operation with Non-Standard Receiver Primaries

A method of color error correction for the Sulphide green and blue phosphors is developed. The method is general in nature and may be used to develop a correction matrix for phosphors with arbitrary color coordinates. A linear matrix is used to obtain an exact coordinate transformation and exact color reproduction within the capabilities of the new phosphors. A non-linear matrix, which gives approximate correction, can be simulated by adjusting the demodulating gains and angles of the color decoder.
