A novel projection system includes a light source, a phase modulator, an amplitude modulator, and a controller having temporal lightfield simulation capabilities. The phase modulator spatially modulates a lightfield from the light source to generate an intermediate image on the amplitude modulator. The amplitude modulator spatially modulates the intermediate image to form a final image. The controller models the phase state of the phase modulator during transitions between phase modulator frames and generates lightfield simulations of the intermediate image during the transition. The controller utilizes the lightfield simulations to generate and provide sets of amplitude drive values to the amplitude modulator at a faster rate than that at which the phase modulator is capable of switching.

A display for displaying image data includes defining virtual color gamuts based on a plurality of primary display colors associated with a light source. At least one of the virtual color gamuts is defined to approximate an established color gamut. Intensity values associated with the virtual color gamuts are generated based on received video data, and the intensity values associated with the virtual color gamuts are used to generate drive values for the primary colors of the light source. A display using one or more virtual color gamuts is also disclosed.

In one embodiment the present invention includes a display system for displaying video. The display system includes a backlight layer and an LCD layer. The display system controls the backlight layer and the LCD layer to emulate a cathode ray tube response. This emulation may be accomplished by applying a gamma function to a gamma corrected input signal. In this manner, the effects resulting from the 'crushed blacks' phenomenon may be reduced.
