1. A display panel, comprising:
a plurality of sub-pixels;
a frame buffer configured to cache a plurality of pieces of bit plane data of each of the sub-pixels corresponding to a frame to be displayed, wherein the plurality of pieces of bit plane data comprise a plurality of pieces of first bit plane data, each of the plurality of pieces of the first bit plane data is used for controlling a corresponding sub-pixel continuously to emit light or not to emit light within a duration (n1×T), n1 is an integer greater than one, different values of n1 correspond to different ones of the plurality of pieces of first bit plane data, the value of n1 is related to a storage bit of the corresponding first bit plane data, and T is a reference duration; and
a source driver electrically connected between the frame buffer and the plurality of sub-pixels, and wherein the source driver is configured to read each piece of the bit plane data at least once and to read at least one piece of the first bit plane data at least twice in the corresponding frame to be displayed, wherein each time the first bit plane data is read, the first bit plane data is used for controlling the corresponding sub-pixel continuously to emit light or not to emit light within a duration T;
wherein the plurality of pieces of first bit plane data comprise at least one piece of first type first bit plane data and at least one piece of second type first bit plane data, one of each of the at least one piece of first type first bit plane data and each of the at least one piece of second type first bit plane data is used for controlling the corresponding sub-pixel continuously to emit light within the duration (n1×T), and the other of each of the at least one piece of first type first bit plane data and each of the at least one piece of second type first bit plane data is used for controlling the corresponding sub-pixel continuously not to emit light in the duration (n1×T);
wherein the source driver is configured to read the second type first bit plane data at least once between reading of one of the at least one piece of first type first bit plane data and reading of the one of the at least one piece of first type first bit plane data at least the second time, or between reading of one of at least two different ones of the at least one piece of first type first bit plane data and reading of other of the at least two different ones of the at least one piece of first type first bit plane data at least the second time;
wherein the plurality of pieces of bit plane data further comprise at least one piece of second bit plane data, each of the at least one piece of second bit plane data is used for controlling the corresponding sub-pixel continuously to emit light or not to emit light within a corresponding duration (n2×T), n2 is greater than 0 and less than or equal to 1, and different values of n2 correspond to different ones of the at least one piece of second bit plane data;
wherein the source driver is configured to control the corresponding sub-pixel continuously to emit light or not to emit light within the duration (n2×T) each time the second bit plane data is read;
wherein the plurality of pieces of first bit plane data comprise at least one piece of first type first bit plane data, at least one piece of second bit plane data comprises at least one piece of first type second bit plane data, one of the first type first bit plane data and the first type second bit plane data is used for controlling the corresponding sub-pixel continuously to emit light within the duration (n1×T) or the duration (n2×T), and the other of the first type first bit plane data and the first type second bit plane data is used for controlling the corresponding sub-pixel continuously not to emit light within the duration (n1×T) or the duration (n2×T); and
wherein the source driver is configured to read the first type second bit plane data at least once between reading of one of the at least one piece of first type first bit plane data and reading of the one of the at least one piece of first type first bit plane data the second time, or between reading of one of two different ones of the at least one piece of first type first bit plane data and reading of other of the two different ones of the at least one piece of first type first bit plane data.
