Pixel circuit, display panel, display device, and composite display device

A pixel circuit, comprising:

• a first subpixel circuit including a first light emitter, a second light emitter, and a first setter, the first setter being configured to set each of the first light emitter and the second light emitter selectively to one of an emissive state or a non-emissive state;
• and
• a second subpixel circuit including a third light emitter, a fourth light emitter, and a second setter, the second setter being configured to set each of the third light emitter and the fourth light emitter selectively to one of the emissive state or the non-emissive state,
• wherein the first subpixel circuit and the second subpixel circuit are in at least one of a connection different state or an emitter number different state, where the connection different state is a state in which a connection between the first light emitter and the second light emitter is one of a series connection or a parallel connection and a connection between the third light emitter and the fourth light emitter is the other of the series connection or the parallel connection, and the emitter number different state is a state in which an emission status of the first light emitter and the second light emitter set by the first setter is in one of a first emission setting or a second emission setting and an emission status of the third light emitter and the fourth light emitter set by the second setter is in the other of the first emission setting or the second emission setting, where the first emission setting is a setting to cause the first light emitter and the second light emitter or the third light emitter and the fourth light emitter to be in the emissive state, and the second emission setting is a setting to selectively cause one of the first light emitter or the second light emitter or one of the third light emitter or the fourth light emitter to be in the emissive state.
