Crosstalk-free dual-view liquid crystal display using patterned E-type polarizer.
We present a dual-view liquid crystal display that allows two faces of the display to be viewed in opposite directions to show different image/video content simultaneously. This device is characterized by a two-domain twisted nematic liquid crystal and a patterned E-type polarizer. Its key optical performance, including the voltage-luminance curve, crosstalk, and viewing angle, has been investigated. When observed at the best viewing angle, the crosstalk between the right and left views is less than 0.07% for all grayscales. In addition, this type of crosstalk can be immune to the misalignment between the polarizers and the liquid crystal layer. For each right/left view, the range of the viewing angle spans roughly 50°.
