1. A display panel driving method, for driving a display panel, the display panel comprising a first display portion, a second display portion, a first timing controller electrically connected to the first display portion, and a second timing controller electrically connected to the second display portion, the method comprising:
by the first timing controller, processing a first display data of the first display portion according to a first combined statistical information to obtain a first target display data, wherein the first combined statistical information is obtained by combining a first statistical information corresponding to the first display data with a second statistical information corresponding to the second display portion;
by the first timing controller, driving the first display portion to display a picture according to the first target display data;
by the second timing controller, processing a second display data of the second display portion according to a second combined statistical information to obtain a second target display data, wherein the second combined statistical information is obtained by combining the first statistical information corresponding to the first display data with the second statistical information corresponding to the second display portion; and
by the second timing controller, driving the second display portion to display a picture according to the second target display data;
wherein the first display portion and the second display portion comprise a plurality of first subpixels and a plurality of second subpixels arranged in a same row, respectively,
wherein the first display data comprises a first current frame display data corresponding to the plurality of first subpixels, and the second display data comprises a second current frame display data corresponding to the plurality of second subpixels,
wherein the first statistical information comprises a first previous frame statistical information, the first previous frame statistical information corresponds to the first previous frame statistical information of a first previous frame display data of the plurality of first subpixels, the second statistical information comprises a second previous frame statistical information, and the second previous frame statistical information corresponds to the second previous frame statistical information of a second previous frame display data of the plurality of second subpixels;
wherein there is a same blanking period between a first previous frame and a first current frame and between a second previous frame and a second current frame, the first previous frame and the first current frame correspond to the first previous frame display data and the first current frame display data, respectively, and the second previous frame and the second current frame correspond to the second previous frame display data and the second current frame display data, respectively,
wherein the processing, by the first timing controller, the first display data of the first display portion according to the first combined statistical information to obtain the first target display data is finished after the blanking period,
wherein the processing, by the second timing controller, the second display data of the second display portion according to the second combined statistical information to obtain the second target display data is finished after the blanking period.
