Abstract

The invention provides a drive method for a display panel, and a display device. The drive method for the display panel is applied to driving the display device which comprises the display panel, and further comprises a time schedule controller, a power supply management chip and a gate electrode driver for providing a gate electrode drive signal for the display panel. The drive method comprises the following steps: sending a corresponding control signal to the power supply management chip according to the screening frequency of a current drive mode through the time schedule controller; sending a corresponding high electric-level signal and a corresponding low electric-level signal to the gate electrode driver according to the control signal through the power supply management chip; and along with the reduction of the scanning frequency, reducing voltage of the corresponding high electric-level signal, and reducing an absolute value of voltage of the corresponding low electric-level signal. When the drive method is used for driving the display panel in a frequency-reducing mode, the power consumption of the liquid crystal display panel is reduced by reducing the voltage of the high electric-level signal and the voltage of the low electric-level signal.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular to a driving method of a display panel and a display device. Background technique

[0002] When the liquid crystal display panel uses metal oxide thin film transistors, due to IGZO (Indium Gallium Zinc Oxide, indium gallium zinc oxide) TFT (Thin Film Transistor, thin film transistor) and a-Si (amorphous silicon) TFT, LTPS (Low Temperature Poly-silicon, low-temperature polysilicon technology) TFT has a leakage current of less than 1pA (picoamp), so when displaying a static picture, even if the driving frequency of the LCD panel is reduced from the original 30-60Hz to 1-5Hz, although the reduction The frequency of driving the TFT is reduced, and the alignment of the liquid crystal molecules can also be maintained without affecting the screen. The down-frequency driving reduces the power consumption due to the reduction in the number of scans per unit time.
