1. A display panel, comprising:
a display substrate comprising a first display region and a second display region adjacent to the first display region, wherein a light transmittance rate of the second display region is greater than a light transmittance rate of the first display region;
a plurality of rows of first pixel driving circuits located in the first display region and a plurality of rows of second pixel driving circuits located in the second display region, wherein a number of the rows of the first pixel driving circuits is greater than a number of the rows of the second pixel driving circuits; and
a plurality of reset signal lines comprising a plurality of first reset signal lines,
wherein a number of the plurality of first reset signal lines is equal to the number of the rows of the first pixel driving circuits, each of the plurality of first reset signal lines is arranged corresponding to one row of the first pixel driving circuits, and each of the plurality of first reset signal lines is electrically connected to a corresponding one row of the first pixel driving circuits;
each row of the second pixel driving circuits are electrically connected to one of the plurality of reset signal lines, one of two adjacent ones of the plurality of first reset signal lines is electrically connected to one row of the second pixel driving circuits, and the other one of the two adjacent ones of the plurality of first reset signal lines is disconnected from the second pixel driving circuits.
