Methods and systems for multiple primary color display

Abstract

Methods and systems for multiple primary color display are provided. Methods and systems of the present invention improve the spectrum efficiency of a color display system, and provide enhanced brightness and color gamut. In an embodiment, methods and systems of the present invention improve the brightness of a color display system employing a high pressure lamp by efficiently incorporating lights components of the lamp output that are outside the red, green, and blue spectrum in creating the color image.

1 . (canceled) 
     
     
         2 . A method for displaying a color image on a display, comprising:
 passing a light through a selective color filter to generate a filtered light, wherein the selective color filter is divided into one or more color filter segments, thereby sequentially passing different color components of the light;   projecting a first color component of said filtered light onto a first modulating panel to generate a first modulated light component;   projecting a second color component of said filtered light onto a second modulating panel to generate a second modulated light component; and   recombining the first and second modulated light components, and projecting the recombined light components onto the display to create the color image;   wherein the one or more color filter segments are sized differently from one another and are of non-primary color, wherein said non-primary color is other than red, blue, green, and yellow.   
     
     
         3 - 5 . (canceled) 
     
     
         6 . A system for displaying a color image, comprising:
 a light source that produces a polychromatic light;   a selective color filter that filters the polychromatic light to generate a filtered light;   a spatial light separator that separates said filtered light into at least first and second beams; and   a light control mechanism that selectively controls the light paths of the first and second beams to create the color image;   wherein the first and second beams represent primary colors, and wherein the selective color filter comprises one or more color filter segments of non-primary color, wherein said non-primary color is other than red, blue, green, and yellow.   
     
     
         7 . A system for displaying a color image, comprising:
 a light source that produces a polychromatic light;   a selective color filter that filters the polychromatic light to generate a filtered light; and   a light control mechanism that selectively controls the light paths of at least first and second color components of the filtered light to create the color image;   wherein the light control mechanism comprises at least first and second light modulating panels, wherein each of said light modulating panels controls the light paths of at least two primary color components of the polychromatic light; and   wherein he selective color filter cycles according to a refresh rate of the color image and comprises one or more color filter segments, including a red/blue filter segment and a yellow/green filter segment.   
     
     
         8 . The system of  claim 7 , wherein the one or more color filter segments consist of non-primary color filter segments. 
     
     
         9 . A system for displaying a color image, comprising:
 a light source that produces a polychromatic light;   a selective color filter that filters the polychromatic light to generate a filtered light, wherein the selective color filter comprises one or more color filter segments of non-primary color, wherein said non-primary color is other than red, blue, green, and yellow; and   a light control mechanism that selectively controls the light paths of at least first and second color components of the filtered light to create the color image;   wherein the light control mechanism comprises at least first and second light modulating panels, wherein each of said light modulating panels controls the light paths of at least two primary color components of the polychromatic light.
