摘要： A display substrate, a display device and a display control method are provided. The display substrate comprises a plurality of pixel units. Each of the plurality of pixel units includes a first region and a second region which is switchable between a non-opaque status and an opaque status. The first region comprises a first light-emitting unit which is a single-sided light-emitting unit. The second region includes at least one color-variable component covering the second region. Each of the at least one color-variable component is switchable between a transparent status and a non-transparent status. The second region is in the non-opaque status in a condition that the at least one color-variable component is in a transparent status. The second region is in the opaque status in a condition that the at least one color-variable component is in a non-transparent status.

摘要： A pixel circuit is provided. A first terminal and a second terminal of a light-emitting sub-circuit are coupled to a first power supply terminal and a compensation sub-circuit respectively. A short-circuiting sub-circuit is coupled to the first terminal and the second terminal of, and short-circuits under control of a short-circuiting control terminal, the light-emitting sub-circuit. The compensation sub-circuit is coupled to a data voltage terminal, a reference voltage terminal, and a first electrode and a gate electrode of a driving transistor. The light-emitting sub-circuit emits a light of brightness in a level corresponding to a current flowing therethrough. The compensation sub-circuit loads, based on the data voltage terminal and the reference voltage terminal, a driving voltage related to a threshold voltage of the driving transistor onto the gate electrode of the driving transistor, such that a current flowing through the driving transistor is not influenced by its threshold voltage.
