1. An array substrate, comprising:
a display area;
a non-display area surrounding the display area;
a base substrate;
a plurality of gate lines, extending in a first direction and arranged in a second direction;
a plurality of data lines, extending in the second direction and arranged in the first direction; wherein the gate lines and the data lines intersect and define a plurality of sub-pixels, the gate lines provide switch control signals for the sub-pixels, and the data lines provide data signals for the sub-pixels;
electrode rows, extending in the first direction and arranged in the second direction; wherein the electrode rows each comprises a plurality of first electrodes, the first electrodes are in the display area, and orthographic projections of at least two of the sub-pixels on a plane, where the base substrate is located, fall within an orthographic projection of a corresponding one of the first electrodes on the plane;
a plurality of switch control lines; and
a plurality of switch units in the display area; wherein the electrode rows each corresponds to at least one of the switch control lines, the first electrodes each corresponds to a respective one of the switch units, and the switch units each comprises at least one first switch;
wherein in one of the electrode rows:
a control terminal of at least one first switch in each of the switch units in the one electrode row is connected to a corresponding one of the switch control lines, first poles of first switches connected to the one switch control line are electrically connected to the first electrodes in the one electrode row respectively, and second poles of the first switches connected to the one switch control line are electrically connected to one another; and
in a display stage, the first electrodes are multiplexed as common electrodes and receive common voltage signals, the one switch control line transmits a first control signal to the first switches connected to the one switch control line, and the first electrodes in the one electrode row electrically connected to the first switches are electrically connected.
