1. A display panel, wherein the display panel comprises: a first base substrate and a plurality of pixels on one side of the first base substrate; each pixel comprises:
a pixel electrode comprising a plurality of pixel sub-electrodes independent from each other and configured to form an electric field with an angle greater than 0 with respect to a direction perpendicular to the first base substrate under control of driving signals;
a common electrode on a side of the pixel electrode away from the first base substrate; and
an electrophoretic liquid layer between the pixel electrode and the common electrode, wherein the electrophoretic liquid layer comprises a plurality of charged particles therein;
wherein the driving signals are provided to the plurality of pixel sub-electrodes; and any one driving signal of the driving signals provided to the plurality of pixel sub-electrodes is different from at least one other driving signal of the driving signals;
wherein the display panel further comprises a plurality of blocking electrode groups; each blocking electrode group is between two adjacent pixels, and is configured to form an electric field to block the plurality of charged particles in the pixel from moving to an adjacent pixel; the electric field formed by the blocking electrode group has a component in a direction parallel to a plane where the first base substrate is located; and
each blocking electrode group comprises: a plurality of strip-shaped blocking electrode portions respectively on both sides of the pixel electrode in an arrangement direction of the plurality of pixel sub-electrodes; the strip-shaped blocking electrode portions on each side of the pixel electrode are independent from each other in the arrangement direction of the plurality of strip-shaped electrodes.
