Claim:
1. A glare reduction panel adapted to be used with a liquid crystal based display device that is configured to receive a first input voltage signal so as to generate a light signal associated with the first input voltage signal and to transmit the light signal through a first liquid crystal layer and subsequently through a second polarizer of the liquid crystal based display device, the glare reduction panel including: a second liquid crystal layer comprising a plurality of liquid crystals, the second liquid crystal layer being configured to receive the light signal from the second polarizer and to receive a second input voltage signal same as the first input voltage signal, so as to excite a set of liquid crystals of the plurality of liquid crystals to adjust a polarization associated with the light signal received by the set of the liquid crystals of the plurality of liquid crystals; and an end polarizer configured to receive the light signal from the second liquid crystal layer, the end polarizer having an axis of transmission relative to an axis of transmission of the second polarizer of the display device; wherein the second liquid crystal layer and the end polarizer are situated to opacify the light signal, received by the set of liquid crystals of the plurality of liquid crystals, by continuing a polarization rotation of the light signal as received by the second liquid crystal layer, based on the second input voltage signal so as to rotate the polarization outside of a 0 to 90 degree range associated with the liquid crystal based display device, wherein the first voltage signal and the second voltage signal are generated and applied to the first crystal layer and the second crystal layer by a sensor when an intensity of light incident on the sensor is greater than a threshold value.
