Display substrate and display device

A display substrate, comprising:

• a plurality of gate lines, each of the plurality of gate lines extending in a first direction;
• a plurality of data lines, each of the plurality of data lines extending in a second direction substantially perpendicular to the first direction, the plurality of gate lines and the plurality of data lines being arranged to intersect to define a plurality of sub-pixels arranged in a plurality of rows and a plurality of columns, every multiple sub-pixels in a same row constituting a pixel unit;
• and
• a plurality of common electrode lines, each of the plurality of common electrode lines extending in the first direction and located between adjacent two of the plurality of gate lines and configured to supply a common voltage to sub-pixels of the plurality of sub-pixels in a same row;
• wherein the display substrate further comprises:
• a plurality of common voltage input line groups extending in the second direction and intersecting with the plurality of common electrode lines;
• wherein common voltage input lines in different groups of the plurality of common voltage input line groups are electrically connected to different common electrode lines of the plurality of common electrode lines, respectively, and among the plurality of common electrode lines, each common electrode line electrically connected to a common voltage input line group of the plurality of common voltage input line groups is different from each common electrode line electrically connected to another common voltage input line group of the plurality of common voltage input line groups, wherein each common electrode line of the plurality of common electrode lines is connected to only one of each common voltage input line of the plurality of common voltage input line groups, wherein the plurality of common electrode lines are divided into a plurality of groups and each group of the plurality of groups of the plurality of common electrode lines is connected to a same common voltage input line of the plurality of common voltage input line groups;
• and
• an orthographic projection of every N columns of pixel units on a substrate covers an orthographic projection of a corresponding common voltage input line group of the plurality of common voltage input line groups on the substrate, where N is an integer greater than or equal to 1.
