Abstract
A liquid crystal (LC) lens structure may include first and second electrode substrates, and an LC layer disposed between the first and second electrode substrates, where each of the first and second electrode substrates include an associated LC alignment layer. The LC lens structure may also include a first lens region and a second lens region separated from the first lens region by an intermediate region. The LC lens structure may also include a first electrode layer having first electrodes segmented into two or more separately addressed electrodes for each of the first and second lens regions. In some examples, an electrical insulation layer may be disposed between the first electrode layer and a second electrode layer including a second electrode positioned within the intermediate region. In other examples, the LC layer may include a polymer wall extending from at least one LC alignment layer in the intermediate region.
