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.
Claims33
A method for displaying a color image on a display, comprising:
- (a) selectively filtering a light to generate a filtered light;
- (b) spatially separating said filtered light into at least first and second beams;
- (c) projecting said at least first and second beams onto a modulating panel to generate at least first and second modulated light beams;
- and
- (d) projecting said first and second modulated light beams onto the display to create the color image.
A method for displaying a color image on a display, comprising:
- (a) selectively filtering a light to generate a filtered light;
- (b) projecting a first color component of said filtered light onto a first modulating panel to generate a first modulated light component;
- (c) projecting a second color component of said filtered light onto a second modulating panel to generate a second modulated light component;
- and
- (d) recombining the first and second modulated light components, and projecting the recombined light components onto the display to create the color image.
A system for displaying a color image, comprising:
- (a) a light source that produces a polychromatic light;
- (b) a selective color filter that filters the polychromatic light to generate a filtered light;
- (c) a spatial light separator that separates said filtered light into at least first and second beams;
- and
- (d) a light control mechanism that selectively controls the light paths of the first and second beams to create the color image, wherein the filtered light is a non-primary color, and wherein a primary color is one of a set of basis colors from which all other colors can be generated
A system for displaying a color image, comprising:
- (a) a light source that produces a polychromatic light;
- (b) a selective color filter that filters the polychromatic light to generate a filtered light;
- and
- (c) 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, and wherein each of said light modulating panels controls the light paths of at least two primary color components of the polychromatic light.
