Claim 0:
1. A display system comprising:
a backlight including a housing receiving one or more light emitting elements to generate and project light from the backlight and one or more reflective portions disposed on the housing;
a first display unit disposed proximate the backlight, wherein the first display unit includes:
an upper substrate,
a monochrome liquid crystal layer cooperating with the upper substrate, wherein the monochrome liquid crystal layer of the first display unit is pixelated, wherein each pixel is dynamically configured to optically rotate polarized light to produce a local dimming backlight at the pixel level, and wherein a periphery of each pixel includes a matrix structure disposed thereon,
a lower substrate disposed opposite the upper substrate and cooperating with the monochrome liquid crystal layer,
a first reflective polarizer having a body including an upper surface and an opposing lower surface that cooperates with the upper substrate, and
a second reflective polarizer having a body including an upper surface cooperating with the lower substrate and an opposing lower surface;

a second display unit disposed proximate the first display unit, wherein the second display unit includes:
an upper substrate,
a color thin film transistor (TFT) display layer cooperating with the upper substrate,
a lower substrate disposed opposite the upper substrate and cooperating with the color TFT display layer,
a first linear polarizer having a body including an upper surface cooperating with the lower substrate of the second display unit and an opposing lower surface; and
a second linear polarizer having a body including an upper surface and an opposing lower surface cooperating with the upper substrate of the second display unit;

a diffuser disposed between the first display unit and the second display unit, wherein the diffuser provides a light profile transition for light transmitted through the first display unit;
a microcontroller for controlling the backlight, the first display unit and the second display unit,
wherein the microcontroller is configured to execute instructions to adjust the monochrome liquid crystal layer of the first display unit between at least a first transmissive state and a second transmissive state;
wherein the matrix structure includes a reflective matrix element configured to reflect the light back to the backlight for recycling;
wherein the matrix structure disposed on the periphery of each of the pixels includes a black matrix structure. the reflective matrix element disposed on a back side of the black matrix structure to reduce reflectivity from a front side of the monochrome liquid crystal layer
wherein the light emitting elements are in a direct type of alignment with the color TFT layer for providing direct lighting thereto;
wherein the light emitting elements are arranged into a plurality of zones, each zone configured to be independently controllable between the first and second transmissive states; and
wherein the color TFT display layer includes a plurality of color pixels in vertical alignment with the zones and the lighting elements.
