Classification: CPC G | IPC G

Claim 15:
16. A display system comprising:
a backlight having a plurality of light emitting elements;
a first colorless display unit disposed proximate the backlight, wherein the first colorless display unit includes:
an upper substrate,
a liquid crystal layer cooperating with the upper substrate, wherein the liquid crystal layer of the first colorless display unit is pixelated, wherein each pixel is dynamically configured to optically rotate polarized light to produce a local dimming of the 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 liquid crystal layer,

a second colored display unit disposed proximate the first colorless display unit;
a microcontroller coupled to the first colorless display unit,
wherein the microcontroller is configured to execute instructions to adjust the liquid crystal layer of the first colorless display unit between at least a first transmissive state and a second transmissive state, the first transmissive state corresponding with polarized light transmitted from the backlight projecting through the liquid crystal layer of first colorless display unit to the second colored display unit, the second transmissive state corresponding with the liquid crystal layer rotating the polarized light transmitted from the backlight up to 90 degrees;
wherein the matrix structure includes a reflective matrix element configured to reflect the light back to the backlight for recycling;
wherein the light emitting elements are in a direct type of alignment with the second colored display unit;
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 second colored display unit includes a plurality of color pixels in alignment with the zones and the lighting emitting elements.
