1. A control system comprising:
a module-group drive state monitor configured to obtain drive state parameters of a display module-group, wherein the drive state parameters reflect a drive state of the display module-group;
a module-group drive controller configured to: determine a current drive state of the display module-group based on the drive state parameters, and select a drive strategy for the display module-group based on the current drive state;
a module-group drive state regulator configured to: drive the display module-group based on the drive strategy that is selected,
wherein:
the drive state parameters comprise: a measured value of an output voltage and a measured value of an output current of a power management integrated circuit supplying power to the display module-group, and a current power consumption value of the display module-group;
the module-group drive state monitor comprises a module-group electrical signal acquisition circuit, the module-group electrical signal acquisition circuit being configured to obtain the measured value of the output voltage, the measured value of the output current, and the current power consumption value;
the module-group drive controller comprises:
an electrical state determination device configured to: determine the current drive state of the display module-group based on the measured value of the output voltage, the measured value of the output current and the current power consumption value;
a drive strategy selector configured to: select a drive strategy for the display module-group based on the current drive state of the display module-group.
