Shift register unit, driving method, gate driving circuit, and display device

A display device, comprising a gate driving circuit, wherein the gate driving circuit comprises at least two cascaded shift register units, and each of the shift register units comprises a shift circuit and a signal integrated circuit;

• wherein
• the shift circuit is respectively connected to a power control end, a first output end, and a second output end, the shift circuit being used to output, to the first output end during a first time period, a power control signal from the power control end, and the shift circuit being further used to output the power control signal to the second output end during a second time period different from the first time period;
• the signal integrated circuit is respectively connected to the power control end, the first output end, the second output end, a first pull-down power end, and a third output end,
• the signal integrated circuit being used to output the power control signal to the third output end in response to the power control signal and a first output signal which is provided by the first output end;
• the signal integrated circuit is further used to output the power control signal to the third output end in response to the power control signal and a second output signal which is provided by the second output end;
• and
• the signal integrated circuit is further used to output, to the third output end at times other than the first time period and the second time period in response to the power control signal, the first output signal and the second output signal, a first pull-down power signal which is from the first pull-down power end.
