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 voltageluminance 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 degrees. (C) 2017 Optical Society of America
