A device includes a primary electrode, a secondary electrode overlapping at least a portion of the primary electrode, and a liquid crystal layer disposed between the primary electrode and the secondary electrode, where the primary electrode has a spatially variable electrical resistance.

GRIN LC lens design with variable resistance electrode

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.

Gradient-index liquid crystal lens having a plurality of independently-operable driving zones

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.
