The chiral nematic liquid crystal is aligned in the Uniform Standing Helix configuration. An in-plane electric field is applied, in the same direction as the surface alignment, which rotates the optic axis via the flexoelectro- optic effect. Crossed polarizers are positioned at ±45° to the direction of the electric field.

The flexoelectro-optic effect provides a fast switching mechanism (τ90-10 ∼ 10–100 μs) suitable for use in field-sequential-color, full motion video displays. An in-plane field is applied to a short-pitch chiral nematic liquid crystal aligned in the Uniform Standing Helix (or Grandjean) texture. The display performance is presented as a function of...

... structure of the device is shown in Fig. 1. The N* is aligned in the USH configuration using anti-planar alignment on the glass surfaces. With no field applied, the helical structure is undistorted, and the device is non-transmissive between crossed polarizers. When an in-plane electric field is applied, the optic axis of the N* rotates, and a birefringence is induced. For a ...

We have fabricated, characterized, and analyzed a recently proposed non-mechanical beam steering device based on the Pancharatnam–Berry phase in a liquid crystal. The architecture of our proposed device employs a linear array of phase control elements (PCEs) to locally control the orientation of the liquid crystal director into a cycloidal pattern...

A backlight that emits collimated light whose direction can be scanned through 16° has been demonstrated. Combined with a high-frame-rate LCD, this could enable a stereo 3-D display that does not require glasses.
