    Abstract: A display panel, a driving method therefor, and a display device. The display panel includes a scan drive module and multiple rows of sub-pixel units arranged in sequence. The multiple rows of sub-pixel units are divided into n sub-pixel unit groups, and two adjacent rows of the sub-pixel units in each sub-pixel unit group are spaced by (n−1) rows of the sub-pixel units in other sub-pixel unit groups. The scan drive module is configured to sequentially scan and drive each row of the sub-pixel units in each sub-pixel unit group and scan and drive the n sub-pixel unit groups in divided periods within a scan cycle.

    Abstract: A drive control circuit, a driving method thereof and a display device are provided. The drive control circuit includes a drive integrated circuit, a transmit control circuit, a scan drive circuit, and a pixel circuit. The drive integrated circuit adjusts a duty cycle of a drive signal to generate a first drive signal and transmits the first drive signal to the transmit control circuit. The drive integrated circuit decreases the amplitude of a data signal to generate a first data signal and transmits the first data signal to the scan drive circuit. The transmit control circuit converts the received first drive signal into a second drive signal with a preset duty cycle and transmits the second drive signal to the pixel circuit. The preset duty cycle of the second drive signal is greater than the duty cycle of the drive signal to be outputted.
