Claim:
1. A touch circuit, characterized by comprising: a touch signal input module having a first output end for outputting a touch drive triggering signal, a second output end for outputting a touch clock signal and a third output end for outputting a touch drive signal; a plurality of touch control sub-circuits cascaded to each other, each of which has a first input end for inputting the touch drive triggering signal and a second input end for inputting the touch clock signal; a plurality of touch drive sub-circuits corresponding to the plurality of touch control sub-circuits respectively and configured to receive the touch drive signal from the touch signal input module; and a plurality of touch electrodes, wherein the first output end and the second output end of the touch signal input module are connected to at least one cascade of the touch control sub-circuits and configured to output the touch drive triggering signal and the touch clock signal to the at least one cascade of the touch control sub-circuits, wherein each of the touch control sub-circuits is configured to control one of the touch drive sub-circuits connected therewith to be conducted or cut off based on the touch drive triggering signal and the touch clock signal, and each of the touch drive sub-circuits is configured to output the received touch drive signal to one of the touch electrodes connected therewith when being conducted.
