1. A pixel structure, comprising:
a plurality of pixel circuits arranged in rows and columns, the plurality of pixel circuits comprising a first type of pixel circuit and a second type of pixel circuit;
a data line electrically connected to the pixel circuits, and used for providing a data voltage to the pixel circuits, wherein the pixel circuits that are in two adjacent rows and electrically connected to one of the data lines are the first type of pixel circuit and the second type of pixel circuit, respectively; and
a plurality of light-emitting elements, comprising a first light-emitting element electrically connected to the first type of pixel circuit and a second light-emitting element electrically connected to the second type of pixel circuit;
wherein a display brightness of the first light-emitting element increases as the data voltage provided to the first type of pixel circuit increases; a display brightness of the second light-emitting element decreases as data voltage provided to the second type of pixel circuit increases;
wherein the first type of pixel circuit comprises a first driving circuit, a first data writing circuit, a first energy storage circuit and a first reference voltage writing circuit;
the first driving circuit is electrically connected to a first node and the first light-emitting element, and is used for generating, under the control of a potential of the first node, a drive current to drive the first light-emitting element;
the first data writing circuit is electrically connected to a scan terminal, the data line and the first node, and is used for controlling, under the control of a scan signal provided by the scan terminal, the data line to provide a data voltage to the first node in a data writing phase;
the first reference voltage writing circuit is electrically connected to an initial control terminal, a first reference voltage terminal and the first node, and is used for writing, under the control of an initial control signal provided by the initial control terminal, a first reference voltage provided by the first reference voltage terminal into the first node in an initialization phase that is before the data writing phase;
the first energy storage circuit is electrically connected to the first node, and is used for storing electrical energy.
