Improving profile of multi-electrode Fresnel-type liquid crystal lens utilizing local control of pretilt angle

A multi-electrode driving Fresnel liquid crystal lenticular lens (MeD-Fresnel type LC lens) for switchable 2D/3D liquid crystal displays has been studied. The demonstrated lens which has fine-patterned electrodes only on one substrate, minimizing lens error by mis-assembly between top and bottom substrate, and uses a discontinuous non-uniform electric field with local control of surface pretilt angle by polymer stabilization technique, exhibits excellent lens profile compared with conventional lens without local control of pretilt angle.
