Adaptive liquid crystal lenses for display applications

• This work is devoted to study of adaptive liquid (LC) lens arrays utilized as a switcher between 2D and 3D autostereoscopic displays. In addition, the adaptive lens array can set and control viewing zones of an autostereoscopic display. The needed spatial distribution of LC director caused the lens effect can be achieved due to a non-uniform electric field or inhomogeneous alignment. In order to obtain a non-uniform electric field, it is necessary a pattered structure of electrodes or a specific design, e.g. non-uniform thickness of a dielectric layer sandwiched between the electrodes and LC. The inhomogeneous alignment is achieved due to a non-uniform distribution of the pre-tilt angle or anchoring energy. Analysis of adaptive LC lenses based on a non-uniform electric field and inhomogeneous alignment is done.
