Abstract

A shift-buffer circuit, a gate driving circuit, a display panel, a display device, and a driving method. The shift-buffer circuit includes: a shift register and a plurality of buffers connected with the shift register. The shift register includes a shift output terminal; the shift register is configured to output a shift output signal from the shift output terminal, in response to a shift clock signal; each of the buffers includes a buffer input terminal and a buffer output terminal, the buffer input terminal being connected with the shift output terminal; each of the buffers is configured to output a buffer output signal from the buffer output terminal, in response to a buffer clock signal.
