1. A display panel, comprising:

  • a plurality of gate lines;

    a plurality of source lines;

    a plurality of first transistors, wherein a control end of each of the first transistors is electrically connected to one of the gate lines and receives a gate signal, and a first end of each of the first transistors is electrically connected to one of the source lines and receives a source signal; and

    a plurality of light emitting diodes (LEDs), wherein a first end of each of the LEDs is electrically connected to a second end of one of the corresponding first transistors, and a second end of each of the LEDs receives a drive signal;

    wherein a frame time of the light emitting diodes comprises at least a first cycle and a second cycle;

    in the first cycle of the frame time, a level of the source signal is higher than a level of the drive signal;

    in the second cycle of the frame time, the level of the source signal is lower than the level of the drive signal; and

    when a period of the first cycle is equivalent to a period of the second cycle, a level difference between the source signal and the drive signal in the first cycle is equivalent to a level difference between the source signal and the drive signal in the second cycle.
