  • Driving method and apparatus of a display panel
    Patent number: 11580902
    Abstract: The present disclosure relates to the technical field of display panels, in particular to a driving method and driving apparatus of a display panel. The driving method may include in response to detecting that the display panel is switched from a dynamic picture to a static picture, generating a refresh rate adjustment instruction; according to the refresh rate adjustment instruction, switching the picture refresh rate of the display panel from a first picture refresh rate to a second picture refresh rate and generating a voltage adjustment instruction; obtaining a target cathode power supply voltage matching the second picture refresh rate; and based on the voltage adjustment instruction and the target cathode power supply voltage, adjusting the display panel to change a working current of each pixel in the display panel.

  • DRIVING METHOD AND DRIVING SYSTEM OF DISPLAY PANEL
    Publication number: 20220223093
    Abstract: The present disclosure relates to the technical field of display panels and provides a driving method and a driving system of a display panel. The driving method of a display panel includes detecting a refresh rate of each frame of the display panel; in response to that the refresh rate of a current frame of the display panel changes relative to the refresh rate of a previous frame of the current frame, generating an adjustment instruction of an initialization voltage; determining a target initialization voltage of the current frame based on the adjustment instruction of the initialization voltage; and at a reset phase of the current frame, initializing a pixel drive circuit of the display panel with the target initialization voltage, so that a difference value between a working current of the pixel drive circuit in the current frame and a working current of the pixel drive circuit in the previous frame is less than a preset threshold.
