摘要： A method for driving a display panel, a display drive device, and a display device. The method includes, during a data refresh stage of at least one display frame, loading a gate turn-on voltage to a gate line, and loading, on each data line, a data voltage of an image to be displayed, so that each sub-pixel inputs a corresponding data voltage, and during a blanking time period, loading a gate turn-off voltage to a gate line, and loading a compensation voltage to each data line. When a data voltage in a sub-pixel connected to a data line is greater than a common electrode voltage, a compensation voltage is less than the data voltage in the sub-pixel connected to the data line, and/or when the data voltage in the sub-pixel is less than the common electrode voltage, the compensation voltage is greater than the data voltage in the sub-pixel.
