Abstract
A method for driving a display panel, and a display apparatus. An example of the method includes: receiving display data of an image to be displayed of the current display frame; and according to the display data, controlling a display panel to sequentially load a gate-on signal to gate lines, and to input a voltage into a data line, and when there is an overlap time between gate-on signals loaded to M adjacent gate lines, a pre-charging voltage and a compensation voltage are sequentially charged to a sub-pixel electrically connected to an Mth gate line among the M gate lines within the overlap time, M being an integer and M≥2.

- and
- controlling the display panel to apply a gate-on signal to gate lines in sequence, and input a voltage to data lines according to the display data;
- wherein in response to gate-on signals loaded on adjacent M gate lines having an overlapping time, during the overlapping time, a pre-charge voltage and a compensation voltage are charged to an sub-pixel electrically connected to an Mth gate line of the M gate lines in sequence;
- wherein M is an integer and M≥2;
- wherein the compensation voltage is triggered by a set edge of a compensation trigger signal to be input to the data line connected to a corresponding sub-pixel;
- wherein the set edge of the compensation trigger signal is one of a rising edge and a falling edge, and the set edge of the compensation trigger signal is within the overlapping time;
- wherein there is a first interval duration between the set edge and a starting moment of the overlapping time, and the first interval duration is not less than 1/2A;
- and
