1. A display panel, comprising:
a first line;
an N-th scan line, wherein at least a portion of the N-th scan line is arranged in a display area of the display panel, and is configured to transmit an N-th level scan signal, wherein N is a positive integer; and
an N-th auxiliary unit, wherein the N-th auxiliary unit is arranged in the display area of the display panel, an output end of the N-th auxiliary unit is electrically connected to the N-th scan line, an input end of the N-th auxiliary unit is electrically connected to the first line, a control end of the N-th auxiliary unit is electrically connected to an (N+M)-th scan line, and M is a positive integer,
wherein the N-th auxiliary unit comprises a plurality of thin film transistors (TFTs), one of a source and a drain of at least one of the TFTs is electrically connected to the N-th scan line, the other one of the source and the drain of the at least one TFT is electrically connected to the first line, and a gate of the at least one TFT is electrically connected to the (N+M)-th scan line, wherein the TFTs are N-channel TFTs, and the first line is configured to transmit a constant low-potential signal,
wherein the control end of the N-th auxiliary unit is electrically connected to an (N+1)-th scan line, the first line is an (N+X)-th scan line, and X is an integer greater than or equal to 2.
