11.2: High Contrast, Wide-Viewing Angle LCD Light Filter

Name: Work Video:
Duration: 3 min 30 s
Description: The paper presents a novel concept of a wide viewing angle LCD light filter, making advantage of the symmetric, highly-twisted complementary dual LC-cell configuration. The resulting overall symmetry allows for very high, continuously variable optical attenuation as well as efficient angular compensation using just simple, cheap negative-birefringent c-plate retarders.
