Provided is a display substrate. A data writing circuit included in each pixel circuit is coupled to a first scanning line, a switching control line, a data signal line, and a drive circuit. The data writing circuit transmits, under the control of the first scanning line and the switching control line, a data signal provided by the data signal line to the drive circuit, such that the drive circuit drives the coupled light-emitting element to emit light. In the same pixel circuit group, each pixel circuit subgroup is coupled to a different switching control line, and the plurality of coupled data signal lines are coupled to the same data line to receive the data signals from the data line. Thus, each pixel circuit, under the control of the switching control line coupled thereto, receives the data signal provided by the data line for the data signal line coupled thereto.

A signal protection circuit, a driving method thereof, and a device. A voltage division circuit divides a voltage of an input signal end and outputs a divided voltage. When the divided voltage is greater than a first threshold voltage and the divided voltage is less than a second threshold voltage, a signal control circuit outputs a first-level switch control signal. In this way, an output control circuit can connect the input signal end with an output signal end in response to the first-level switch control signal. When the divided voltage is less than the first threshold voltage or the divided voltage is greater than the second threshold voltage, the signal control circuit may output a second-level switch control signal. In this way, the output control circuit can connect the input signal end with a ground terminal in response to the second-level switch control signal.

The comparison sub-circuit is coupled to a first reference voltage end, a second reference voltage end, a feedback voltage end and a comparison output end which is coupled to the switching sub-circuit. The switching sub-circuit is further coupled to an output voltage end, an initial voltage end and a replacement voltage end. The comparison sub-circuit determines whether a voltage of the feedback voltage end is between the first reference voltage and the second reference voltage. The switching sub-circuit transmits a voltage of the initial voltage end to the output voltage end in response to a first control signal of the comparison output end; transmit a voltage of the replacement voltage end to the output voltage end in response to a second control signal of the comparison output end.
