Oblique light incidence onto hybrid aligned nematic (HAN) cells for optical compensators

Design and fabrication methods of HAN cells with arbitrary LC pretilt angle value are described. Phase retardation ΔΦ values for the hybrid LC vs. the LC pretilt angles θ0(1), θ0(2) on the opposite cell's substrates are calculated for arbitrary light incidence angle. LC director configuration is suggested for its application in optical compensators. LC pretilt angle value is measured in the HAN cells with given planar or vertical LC alignment on one of the substrates. © 2014 Society for Information Display

Optical properties of hybrid aligned nematic cells with different pretilt angles

The phase retardation difference, ΔΦ, is calculated for hybrid liquid crystal (LC) cells as a function of LC pretilt angles, Θ(1) 0, Θ(2) 0, on the opposite substrates of the cell for the case of an arbitrary angle of light incidence in the range from 0 to 90°. An LC director configuration is suggested for its application in optical compensators. Design and fabrication methods of hybrid aligned nematic (HAN) cells with an arbitrary LC pretilt angle are described.

O-80: Different polarity NLC alignment on organosilicon films of varying molecular structure

LC pretilt angle has been measured by using of optical methods for LC cells with organosilicon (OS) aligning films of different molecular structure. The effect depends on mesogens polarity. An opportunity of LC pretilt angle in wide range from 0 to 90° by varying the OS chemical structure is demonstrated
