LIQUID CRYSTAL LENS

摘要

A crystal lens includes a liquid crystal layer, a pair of alignment layers, a first electrode set, and a second electrode set. The alignment layers are positioned on different sides of the liquid crystal layer. The first and second electrode sets are positioned on different alignment layers. The first electrode set includes a first transparent insulating layer and a first electrode layer. The first electrode set attaches to one of the alignment layers. The second electrode set includes a second transparent insulating layer, a second electrode layer, and a dielectric film. The second electrode layer includes a hole-patterned electrode. The dielectric film attaches to the first transparent insulating layer. The hole-patterned electrode exposes the dielectric film. In addition, an external power supply provides a driving voltage to the hole-patterned electrode and the first electrode layer, so that the liquid crystal molecules inside the liquid crystal layer drive rotation.
