1. A method for driving a display module comprising a display screen and a sensor configured to collect a target parameter, comprising:
generating a frame reference signal in response to a display instruction;
transmitting a light emission control signal to a plurality of pixels in the display screen based on the frame reference signal, wherein the light emission control signal at a first level is configured to control the plurality of pixels to emit light, and the light emission control signal at a second level is configured to control the plurality of pixels not to emit light; and
transmitting a turn-on signal to the sensor based on the frame reference signal, wherein the turn-on signal is configured to control the sensor to collect the target parameter, and the turn-on signal is not overlapped with a period when the light emission control signal is at the first level;
wherein transmitting the light emission control signal to the plurality of pixels in the display screen based on the frame reference signal comprises:
transmitting the light emission control signal to the plurality of pixels in the display screen based on a turn-on transition edge of the frame reference signal;
wherein for a turn-on transition edge and a turn-off transition edge of the light emission control signal at the second level, a duration from one transition edge of the light emission control signal to the turn-on transition edge of the frame reference signal is a fixed duration, and a duration from another transition edge of the light emission control signal to the turn-on transition edge of the frame reference signal is negatively correlated with target brightness of the plurality of pixels.
