Abstract
A display panel includes a shift register including stages of shift circuits arranged in cascade. At least one of the shift circuits includes a driving unit and a gating unit. The driving unit has a first node and a second node, outputs a second level when a potential of the first node is a first level, and outputs the first level when a potential of the second node is the first level. The gating unit includes a first control module and a gating output module. The first control module writes a signal of the first node into a third node when a frequency control signal received by the first control module is the first level. The gating output module outputs the second level when a potential of the third node is the first level and output the first level when a potential of the second node is the first level.
