1. A display substrate, comprising:
a base substrate comprising a display area and a frame area located on at least one side of the display area;
a plurality of pixel islands arranged in an array in the display area; wherein each pixel island comprises a plurality of sub-pixels arranged in an array;
a plurality of data lines extending along a column direction and arranged along a row direction in the display area, the plurality of data lines being electrically connected to the sub-pixels;
a plurality of operational amplifiers located in the frame area; wherein each operational amplifier is electrically connected to a column of sub-pixels through the data line;
a plurality of reusing circuits located in the frame area; wherein each reusing circuit is connected to at least two operational amplifiers, and sub-pixels electrically connected to each reusing circuit through data lines are located in at least two columns;
wherein at least two adjacent columns of pixel islands in the row direction form a partition; each reusing circuit comprises a first sub-reusing circuit, and sub-pixels electrically connected to each first sub-reusing circuit are located in at least two partitions;
each first sub-reusing circuit is connected among two operational amplifiers and among data lines to which the two operational amplifiers are electrically connected, and the sub-pixels electrically connected to each first sub-reusing circuit are in two partitions;
wherein there are 2n partitions in the row direction, n is a positive integer; first to nth partitions arranged continuously are a watching area, and (n+1)th to 2nth partitions arranged continuously are a non-watching area; the sub-pixels electrically connected to each first sub-reusing circuit are located in the mth and (m+n)th partitions, wherein m is an integer greater than or equal to 1 and less than or equal to n; wherein a refresh rate of the watching area is greater than a refresh rate of the non-watching area;
each partition comprises i columns of pixel islands, each pixel island comprises k sub-pixels arranged in a single row, i is an integer greater than or equal to 2, and k is an even number;
the sub-pixels electrically connected to each first sub-reusing circuit are at least part of sub-pixels in a hth column of the sub-pixels in the jth column of the pixel island in the mth partition, and at least part of sub-pixels in a hth column of the sub-pixels in the jth column of the pixel island in the (m+n)th partition, wherein j is an integer greater than or equal to 1 and less than or equal to i, and h is an integer greater than or equal to 1 and less than or equal to k.
