Electrically tunable liquid crystal lens set with central electrode |
摘要 |
A liquid crystal lens cell set includes a plurality of liquid crystal lenses overlapping to each other. Each of the liquid crystal lenses is supported between a pair of flat layers. One of the layers supports a planar electrode made of ITO. The other electrode, also formed of ITO, is supported in the center of the opposing substrate and projects toward the center of the liquid crystal layer. A power supply creates a potential difference between the electrodes and imposes a non-uniform electric field on the liquid crystal modules which aligns them in which a way as to act as a lens. By varying voltage between the electrodes the focal length of the lens may be controlled. A central electrode may be in the form of a beam or of a pointed tip. An electrode having a central hole may be associated with the central electrode or the planar electrode.
