1. A method for driving a display panel, comprising:
determining a brightness mode of the display panel, wherein a same display grayscale in different brightness modes corresponds to different data voltages;
determining a data voltage characterization value according to the brightness mode, wherein the data voltage characterization value is used for characterizing a data voltage level of the brightness mode;
determining a holding voltage corresponding to the data voltage characterization value according to the data voltage characterization value; and
inputting, in a display holding frame of a current display image, the holding voltage to a source electrode of a drive transistor in each sub-pixel of the display panel.
