Driving circuit unit, panel driving circuit and display device

The invention relates to a driving circuit unit, a panel driving circuit and a display device, the driving circuit unit comprises an input switch transistor, an output transistor, a control transistor and a clock overcurrent protection unit, a first input signal output by a first input signal end is transmitted to a control node through the input switch transistor under the control of the first input signal end, and a second input signal output by the output transistor is transmitted to the control node; a gate closing signal provided by a third input signal end is transmitted to a control node through a control transistor under the control of a second input signal end, so that an output transistor can output a gate driving signal based on a clock signal provided by a clock signal end under the control of the control node; and when the current value of the gate driving signal is greater than the preset current threshold value, the clock overcurrent protection unit feeds back an overcurrent detection signal to
