Abstract
The present disclosure provides a display substrate and a display device. The display substrate includes a driving circuit, a light-emitting element, a first light-emitting control circuit, a first control circuit, a second control circuit, a third control circuit, a data writing-in circuit and an energy storage circuit. The first control circuit is configured to control to connect the first voltage line and a first end of the light-emitting element under the control of the first control signal; the second control circuit is configured to control to connect the reference voltage line and the second end of the light-emitting element under the control of a second control signal; the third control circuit is configured to control to connect the first end of the energy storage circuit and the control end of the driving circuit under the control of a third control signal.
