Driving circuit unit, display driving circuit and display device

The invention relates to a driving circuit unit, a display driving circuit and a display device, and the driving circuit unit comprises an input switch transistor, an output transistor and a control transistor, the output transistor is integrated with an integrated capacitor, and the integrated capacitor is connected with the input switch transistor through the input switch transistor under the control of a first input signal end. A first input signal output by a first input signal end is transmitted to a control node, and a gate closing signal provided by a third input signal end is transmitted to the control node through a control transistor under the control of a second input signal end, so that an output transistor is controlled by the control node to close a gate. A gate driving signal is output based on a clock signal provided by a clock signal end and a voltage signal provided by an integrated capacitor, and an output transistor can store energy through the integrated capacitor integrated in the output
