A liquid crystal lens has at least two driving regions, and the liquid crystal lens includes a first electrode layer and a second electrode layer. The first electrode layer includes a plurality of first electrode groups, and each first electrode group includes a plurality of first electrodes. The plurality of first electrodes included in each first electrode group is configured to receive a plurality of first driving signals in a one-to-one correspondence manner, and each driving region in the at least two driving regions corresponds to at least one first electrode group. The second electrode layer is disposed opposite to the first electrode layer, and includes at least one second electrode configured to receive at least one second driving signal in a one-to-one correspondence manner.
