It has become increasingly recognized that multicolor operation of a data display is as desirable as multicolor operation of video. Historically, this achievement has proved one of the most difficult in display technology. Attempts to achieve color reach back in time almost as far as the use of the CRT for display purposes. Very early it was suggested that the use of a variable color filter in conjunction with synchronous frame-sequential color encoding could achieve the desired effect. All the electronic color filters to date are believed to rely on the modulation of polarization as an intermediate mechanism. Two distinct methods of this type can be envisioned: 1. Use of the electronic filter as a broad-band half-wave plate, (as described in [1]) used in conjunction with fixed chromatic polarizers. 2.
