1. A display panel, comprising: a first base substrate and a second base substrate which are opposite to each other, and a plurality of lens imaging modules; wherein
the first base substrate comprises a plurality of pixel units arranged in an array, and each of the lens imaging modules comprises an image sensor and a lens unit with an adjustable focal length; and
the plurality of lens imaging modules are between the first base substrate and the second base substrate, an orthogonal projection of the lens imaging module on the first base substrate is between two adjacent pixel units; the lens imaging module comprises a first substrate and a second substrate which are opposite to each other, and the image sensor and the lens unit are between the first substrate and the second substrate;
the lens unit comprises:
a first electrode and a second electrode, wherein the first electrode is on a side of the first substrate facing the second substrate, the second electrode is on a side of the second substrate facing the first substrate, and extension directions of both the first electrode and the second electrode are parallel to a direction of a plane of the first substrate;
a third electrode and a fourth electrode which are opposite to each other, wherein extension directions of both the third electrode and the fourth electrode are perpendicular to a direction of a plane of the first electrode, and the first electrode, the second electrode, the third electrode, and the fourth electrode are insulated from one another;
a first insulating retaining wall, wherein an extension direction of the first insulating retaining wall is perpendicular to the direction of the plane of the first electrode, and defines an enclosed space with the first electrode, the second electrode, the third electrode, and the fourth electrode;
a second transparent insulating liquid filled in the enclosed space; and
a liquid lens in the second transparent insulating liquid.
