Classification: CPC G | IPC F  G

Claim 0:
1. A display system comprising:
an extended illumination source configured to emit light over an extended emission surface of the extended illumination source and comprising at least one light source;
a first liquid crystal assembly configured to selectively transmit and reflect light received from the extended emission surface of the extended illumination source, the first liquid crystal assembly disposed on the extended illumination source and comprising:
a bottom reflective polarizer facing the extended illumination source and configured to substantially transmit light having a first polarization state and substantially reflect light having an orthogonal second polarization state;
a top reflective polarizer facing away from the extended illumination source and configured to substantially transmit light having the second polarization state and substantially reflect light having the first polarization state; and
a bottom liquid crystal panel disposed between the top and bottom reflective polarizers and configured to selectively and at least partially transmit and reflect light transmitted by the bottom reflective polarizer; and

a second liquid crystal assembly configured to receive light from the first liquid crystal assembly and emit an image for viewing by a viewer, the second liquid crystal assembly disposed on the first liquid crystal assembly and comprising:
a top absorbing polarizer facing away from the first liquid crystal assembly and configured to substantially transmit light having the first polarization state and substantially absorb light having the second polarization state; and
a top liquid crystal panel disposed between the top absorbing polarizer and the first liquid crystal assembly and configured to receive light transmitted by the first liquid crystal assembly and form an image for viewing by the viewer.
