Claims
- 1. An apparatus having a circuitry for addressing a light valve that is to be illuminated by moving bands of first, second and third color in order to provide a full color display, said light valve including row and column drivers, said circuitry comprising:
- means for providing separate video signals corresponding to each of the first, second and third colors;
- delay means for delaying said separate video signals for varying amounts of time;
- serializing means for providing a single serial stream of signals corresponding to said first, second and third colors in sequential order;
- means for applying said serialized stream to the column drivers of said light valve; and
- means for activating said row drivers, said row drivers being activated in non-sequential order to correspond with the color bands being applied to the row.
- 2. The apparatus as claimed in claim 1 further including analog-to-digital converters disposed before said delay means and digital-to-analog converters disposed between said circuitry and said light valve so that the signal processing takes place in a digital format.
- 3. The circuitry as claimed in claim 1 wherein said video signals correspond to successive frames of the first, second and third colors, and said delay between colors comprises one-third of a frame.
- 4. The circuitry as claimed in claim 3 wherein said row drivers are activated one-third of a frame apart so as to track the bands of light.
- 5. The apparatus as claimed in claim 1 wherein said light valve includes four column drivers and said circuitry includes means for selectively applying said serialized stream to said four column drivers.
- 6. The circuitry as claimed in claim 1 wherein said row drivers comprise three row drivers.
