Claim:
1. An optical display system comprising: a polarizer; an integrated back light unit optically connected to a first face of the polarizer, wherein the integrated back light unit comprises at least one light emitting diode mounted on a support in a side-emitting configuration that provides illumination to a front side of the support, wherein the at least one light emitting diode is located on, and extends parallel to, a major surface of the support, and emits light parallel to the major surface of the support, and the integrated back light unit further comprises a waveguide that directs light from the at least one light emitting diode toward the front side of the support and to the first face of the polarizer; and a display comprising an array of pixels optically connected to a second face of the polarizer, wherein the first face of the polarizer and the second face of the polarizer are not parallel; and wherein the polarizer is configured to direct light from the integrated back light unit to the display.
