1. A display driving device, comprising:
a power supply module configured to output a first power supply voltage and a second power supply voltage; and
a display panel comprising a power interface electrically connected to the power supply module, the power interface being configured to input the first power supply voltage and the second power supply voltage, the display panel further comprising light-emitting transistors, a first terminal of each of the light-emitting transistors being used for receiving the first power supply voltage and a second terminal of each of the light-emitting transistors being used for receiving the second power supply voltage, the display panel being divided into a plurality of display regions based on distances between each of the light-emitting transistors and the power interface, each display region comprising a subset of the light-emitting transistors;
wherein the power supply module is further configured to output a first regulated voltage and/or a second regulated voltage for a target display region from which a distance to the power interface is greater than a preset distance, to regulate a first terminal voltage of the light-emitting transistor of a respective subset in the target display region by the first regulated voltage and/or regulate a second terminal voltage of the light-emitting transistors of the respective subset by the second regulated voltage.
