OPTICAL AXIS TUNABLE LIQUID CRYSTAL LENS, ELECTRONIC APPARATUS, DISPLAY APPARATUS, AND METHOD OF OPERATING OPTICAL AXIS TUNABLE LIQUID CRYSTAL LENS

摘要

An optical axis tunable liquid crystal lens (10) includes a liquid crystal layer (200); and a control electrode configured to adjust an optical axis of the optical axis tunable liquid crystal lens (10). The control electrode includes a first electrode (310) configured to be provided with a common voltage signal (Vc) and a second electrode (320) configured to be provided with a control voltage signal. The first electrode (310) is on a side of the liquid crystal layer (200) away from the second electrode (320). The second electrode (320) includes a first sub-electrode (321) and a second sub-electrode (322) spaced apart from each other and being on two opposite sides with respect to a center of the second electrode (320), the first sub-electrode (321) and the second sub-electrode (322) being independently addressable, the first sub-electrode (321) configured to be provided with a first voltage signal (V1) and the second sub-electrode (322) configured to be provided with a second voltage signal (V2).
