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

A shift register unit, comprising a first input circuit, a second input circuit, an output circuit, a first control circuit, and a second control circuit,

• wherein the first input circuit is electrically connected to a first node, and is configured to transmit an input signal to the first node under control of a first clock signal;
• the second input circuit is electrically connected to the first node and a second node, and is configured to control a level of the second node under control of a level of the first node or the first clock signal;
• the first control circuit is electrically connected to the second node and a third node, and is configured to control a level of the third node under control of the level of the second node and a second clock signal;
• the output circuit is electrically connected to the third node, a second high voltage signal line and an output terminal, and is configured to output an output signal to the output terminal under control of the level of the third node;
• and
• the second control circuit is electrically connected to the first node, the third node and a first high voltage signal line, and is configured to control the level of the third node under control of the level of the first node,
• wherein the first high voltage signal line and the second high voltage signal line are two different voltage signal lines.
