Driving unit, driving method, driving circuit of touch driving electrode, and touch display device

A driving unit of a touch driving electrode, comprising:

• a start signal shift sub-unit, connected to a start control signal output terminal, and configured to control the start control signal output terminal to output a first level under the control of a start signal, the first level, a second level, a first clock signal and a second clock signal during an adjacent time period next to a time period in which a potential of the start signal is the first level, then reset the start control signal so as to control the start control signal output terminal to output the second level;
• and
• a touch driving signal output sub-unit, connected to a touch driving signal output terminal, a touch signal input terminal, a touch scanning input terminal and the start control signal output terminal, and configured to control the touch driving signal output terminal to output a touch scanning signal under the control of the start control signal when a potential of the start control signal and a potential of the touch control signal are both the first level,
• wherein a phase of the first clock signal is opposite to that of the second clock signal.
