摘要： An optical element includes a first optical substrate, a second optical substrate overlying at least a portion of the first optical substrate, a liquid crystal layer disposed within a cell gap between the first optical substrate and the second optical substrate, and a plurality of carbon nanotube pillars extending between the first optical substrate and the second optical substrate across the cell gap. The carbon nanotube pillars may have an aspect ratio of at least approximately 2:1, and may be configured to maintain a uniform cell gap thickness.

摘要： A lens system may include a lens having a first electrode electrode layer, a second electrode layer, and a liquid crystal layer disposed between the first electrode layer and the second electrode layer. The lens may be divided into a plurality of lens segments that are concentrically arranged proceeding from a center to a radially outer periphery of the lens. An optical power of a first lens segment of the plurality of lens segments may be greater than an optical power of a second lens segment of the plurality of lens segments disposed radially outward relative to the first lens segment. Various other devices, systems, and methods are also disclosed.

摘要： A lens system may include a lens having a liquid crystal layer and a driving electrode array disposed on a first side of the liquid crystal layer, the driving electrode array including a plurality of driving zones that are independently operable. The plurality of driving zones may each include a plurality of driving electrodes consecutively arranged along a radial direction extending from a central region of the lens. The lens system may include a controller that is configured to independently operate each of the plurality of driving zones via a separate plurality of bus lines coupled to each of the plurality of driving zones. The controller may be configured to operate at least one of the driving zones based on a gaze direction of the user. Various other devices, systems, and methods are also disclosed.
