Claim:
1. A locally dimmed high dynamic range display system comprising: an emitter, said emitter comprising an array of light emitting elements of similar color controlled in a locally dimmed configuration and emitting light into an optical path; a diffuser, said diffuser diffusing said light emitted from said emitter; a color layer configured to receive light from said diffuser and mitigate crosstalk by emitting different and smaller passband-like color bands of distinct colors and provide a specific color gamut; wherein said emitter as locally dimmed comprises a first modulator configured to transmit light through said diffuser and said color layer; wherein said color layer placed in said optical path at a point where the light is collimated and said color layer is configured to perform a convolution upon light emitted from the said first modulator which operates in conjunction with a second modulator and other optical components together configured to produce a desired color gamut of the display and an image to be displayed by the display; the second modulator comprising an LCD panel having color filters operative on the passband like color bands which are small enough that crosstalk between light in the color bands passing through the filters is eliminated, said second modulator modulating light from said first modulator in a manner without color overlap such that each color filter of the LCD panel acts independent of adjacent color filters; and a controller, said controller receiving input image data and sending control signals to said first and said second modulators.
