Abstract:
1. A liquid crystal lens, comprising: a first light-pervious plate; a second light-pervious plate opposite to the first light-pervious plate; a liquid crystal layer sandwiched between the first light-pervious plate and the second light-pervious plate; a first electrode layer comprising a plurality of concentric, annular electrodes arranged on a surface of the first light-pervious plate, a material of the first electrode layer being carbon nanotubes; insulating glue, each two adjacent annular electrodes being electrically insulated by the insulating glue; a second electrode layer arranged on a surface of the second light-pervious layer; and a driving voltage chip for providing voltages between each of the annular electrodes and the second electrode layer, the voltages applied thereto being in radial gradient distribution.
