Abstract
A driving circuit and a driving device for a display panel, and the driving circuit for the display panel includes: a stretching circuit, a control circuit, a bootstrapping circuit, and an output circuit; the control circuit is respectively electrically connected with the stretching circuit, the bootstrapping circuit, and the output circuit, and the bootstrapping circuit is electrically connected with the output circuit. The stretching signal generated by the stretching circuit can enable the bootstrapping circuit to have enough time to be charged, and ensure that the output circuit can reach or exceed the preset potential when receiving the bootstrap signal, thereby the voltage being not stable when the gate driving signal is output is avoided, and the phenomenon that the gate driving signal is stopped in advance is avoided.
