Patent ID: 7057668

Claim:
A color sequential display system operable in a monochrome mode comprising: a) a video signal source which generates a composite video signal containing a luminance signal Y s and primary color signals R s , B s , and G s 3 ; b) a light source adapted to flash light of each of the primary colors R, B, or G or a white light W; c) a display optically coupled to the light source, said display having an array for displaying (i) an image of the R s , B s , and G s , signals in succession at a rate of 150–240 Hz in a color sequential mode or (ii) displaying an image of the luminance signal Y s in succession at a rate of 50–60 Hz in a monochrome mode; and d) a control for the light sources which, in the color sequential mode, flashes light of each of the primary colors in synchronism with the respective image display of the R s , B s & G s signals and in the monochrome mode, flashes the white light or light of all of the primary colors simultaneously in synchronism with the display of the luminance signal Y s .
