Abstract:
A reflective liquid crystal on silicon (LCOS) display comprises a transparent substrate, a reflective substrate, and liquid crystal fluid between the substrates. The LCOS display further comprises a matrix of pixels, arranged in a plurality of rows and columns, wherein an intersection of a row and a column defines a position of a pixel in the matrix. The LCOS display has tilt angles sufficient to overcome disclinations due to fringe fields, and, at the same time, achieves high contrast. The surface azimuthal direction of the molecules of the liquid crystal fluid is either substantially parallel or perpendicular to the direction of polarization of incoming incident linearly polarized light. Light leakage is minimal because the effective birefringence as seen by the incoming incident linearly polarized light is substantially zero and does not depend on the pretilt of the molecules of the liquid crystal fluid. Between the transparent substrate and the reflective substrate, the twist of the molecules of the liquid crystal fluid may vary from about 0 degrees to about 90 degrees when in the “OFF” state.
