1. A driving method for a display panel, comprising:
acquiring display data of a to-be-displayed image in a current display frame; and
loading a data voltage on a data line in the display panel according to the display data, such that each sub-pixel in the display panel is charged with the data voltage; wherein
a first target duration is between an end time point of a voltage conversion edge when the data line is loaded with a positive data voltage and a start time point of a data charging stage corresponding to the sub-pixel charged with the positive data voltage, a second target duration is between an end time point of a voltage conversion edge when the data line is loaded with a negative data voltage and a start time point of a data charging stage corresponding to the sub-pixel charged with the negative data voltage, and the second target duration is larger than the first target duration;
a voltage conversion rate of the voltage conversion edge when the data line is loaded with the positive data voltage is a first conversion rate;
a voltage conversion rate of the voltage conversion edge when the data line is loaded with the negative data voltage is a second conversion rate;
a start time point of the voltage conversion edge when the data line is loaded with the positive data voltage is later than the start time point of the data charging stage corresponding to the sub-pixel charged with the positive data voltage, and a first interval duration is between the start time point of the voltage conversion edge when the data line is loaded with the positive data voltage and the start time point of the data charging stage corresponding to the sub-pixel charged with the positive data voltage;
a start time point of the voltage conversion edge when the data line is loaded with the negative data voltage is later than the start time point of the data charging stage corresponding to the sub-pixel charged with the negative data voltage, and a second interval duration is between the start time point of the voltage conversion edge when the data line is loaded with the negative data voltage and the start time point of the data charging stage corresponding to the sub-pixel charged with the negative data voltage; wherein
after the acquiring the display data of the to-be-displayed image in the current display frame, and before the loading the data voltage on the data line in the display panel according to the display data, the driving method further comprises:
determining the first conversion rate and the second conversion rate, and/or the first interval duration and the second interval duration; and
the loading the data voltage on the data line in the display panel according to the display data, comprises:
loading the data voltage on the data line in the display panel by using the determined first conversion rate and second conversion rate, and/or the determined first interval duration and second interval duration according to the display data.
