Signal Generating Unit, Shift Register, Display Device And Signal Generating Method

A signal generating unit, comprising:

• a first output transistor disposed between an output node and a first power node, the first power node configured for receiving a high-level power supply signal;
• a second output transistor disposed between the output node and a second power node, the second power node configured for receiving a low-level power supply signal;
• a first-node potential control module, configured to output a first control signal to a gate electrode of the first output transistor under control of an inputted start signal;
• a second-node potential control module configured to output a second control signal, which has an opposite phase with the first control signal, to a gate electrode of the second output transistor;
• and
• a first capacitor structure connected with the gate electrode of the first output transistor, and configured to be charged when the first-node potential control module outputs a single-pulse-width level signal for controlling the first output transistor to be switched on, and to maintain the gate electrode of the first output transistor in an on state during a subsequent time period having one pulse width.
