Abstract
A Fresnel liquid crystal lens structure includes a first substrate and a second substrate arranged oppositely, a first electrode, a second electrode, and a liquid crystal layer located therebetween, wherein the first electrode is a plate-shaped electrode, the second electrode includes concentric ring electrodes; concentric ring electrodes are divided into electrode groups in a first direction to divide the formed Fresnel liquid crystal lens into lens regions; each electrode group is divided into sub-electrode groups arranged periodically in a first direction to divide each lens region into sub-lens regions arranged periodically; and each sub-electrode group includes electrodes to form a sub-lens region having a step shape and the quantity of electrodes in a sub-electrode group within a different electrode set is different. A display device including the Fresnel liquid crystal lens structure and a method for driving a Fresnel liquid crystal lens are also provided.
