    Abstract: Embodiments of the present disclosure provide a protection circuit and method, a pixel circuit, and a display device. The protection circuit comprises a determination circuit, a first coupling circuit, a first terminal and a second terminal. The determination circuit is coupled to the first terminal and the first coupling circuit, and is configured to determine whether the voltage at the first terminal of the protection circuit belongs to one of a first predetermined range and a second predetermined range. The first coupling circuit is coupled to the first terminal, the second terminal and the determination circuit, and is configured to: couple the first terminal to the second terminal in response to the voltage at the first terminal belonging to the first predetermined range; and decouple the first terminal from the second terminal in response to the voltage at the first terminal belonging to the second predetermined range.

    Abstract: A pixel circuit, a method for driving a pixel circuit and a display panel are provided. The pixel circuit includes a control sub-circuit, a shunt sub-circuit, a light emitting sub-circuit and a latch sub-circuit, where the control sub-circuit is configured to output to the latch sub-circuit a data signal from a data signal line in response to a scan signal from a scan signal line; the latch sub-circuit is configured to latch a first level signal and a second level signal in response to the data signal and the scan signal, and output the second level signal to light emitting sub-circuit in response to a switch signal from a switch signal line, to enable the light emitting sub-circuit to emit light; and the shunt sub-circuit is configured to shunt, in response to a control signal from a control signal line, the second level signal input to the light emitting sub-circuit, to adjust a light emitting brightness of the light emitting sub-circuit.
