Claim:
1. A stage of a driving unit in a driving circuit for touch driving electrodes, comprising: a signal conversion unit with a signal input terminal, a clock input terminal and a signal output terminal, the signal conversion unit being configured to convert a signal input from the signal input terminal under a control of a clock signal input from the clock input terminal and to output a conversion result at the signal output terminal; a logic computation unit having a first input terminal connected to the signal input terminal of the signal conversion unit and a second input terminal configured to receive a touch enable signal, the logic computation unit being configured to perform a logic computation on the input signal received at the first input terminal and the touch enable signal received at the second input terminal and to output a computation result; a buffer unit connected to an output terminal of the logic computation unit; and an output unit connected to an output terminal of the buffer unit and configured to output a touch scan signal to the touch driving electrode under a control of a signal output by the buffer unit, wherein the signal conversion unit is configured to output the conversion result to a signal conversion unit of a next stage of the driving unit, and wherein the clock signal of the stage of the driving unit has a phase opposite to that of the next stage of the driving unit.
