Abstract: The application discloses a liquid crystal display panel and a display device. In the liquid crystal display panel, each pixel unit includes a first sub-pixel and a second sub-pixel. The polarities of the data voltages received by two adjacent pixel units sharing the same data line are opposite. In each pixel unit, the driving timing of the first sub-pixel is earlier than the driving timing of the second sub-pixel, and the duty cycle of the scan signal received by the first sub-pixel is greater than the duty cycle of the scan signal received by the second sub-pixel.

Abstract: A backlight driving circuit and a display device are provided. The backlight driving circuit includes a light-emitting unit, a detection module, a power supply chip, and a voltage regulating module. The detection module receives a preset voltage and is electrically connected to a second electrode of the light-emitting unit to output a control voltage. The power supply chip is configured to output a reference voltage. The voltage regulating module receives the control voltage and the reference voltage, and is electrically connected to a first electrode of the light-emitting unit and a ground terminal to output a power supply voltage to the first electrode of the light-emitting unit.
