Abstract
A method and device for driving a display panel and a display device. The method for driving a display panel includes: determining a brightness mode of the display panel, where the same display grayscale corresponds to different data voltages in different brightness modes; determining a data voltage characterization value according to the brightness mode, where the data voltage characterization value is used for characterizing a data voltage level in 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.
