Abstract
An optical axis tunable liquid crystal lens includes a liquid crystal layer; and a control electrode configured to adjust an optical axis of the optical axis tunable liquid crystal lens. The control electrode includes a first electrode configured to be provided with a common voltage signal and a second electrode configured to be provided with a control voltage signal. The first electrode is on a side of the liquid crystal layer away from the second electrode. The second electrode includes a first sub-electrode and a second sub-electrode spaced apart from each other and being on two opposite sides with respect to a center of the second electrode, the first sub-electrode and the second sub-electrode being independently addressable, the first sub-electrode configured to be provided with a first voltage signal and the second sub-electrode configured to be provided with a second voltage signal.
