Abstract
A touch screen, a touch driving circuit and a touch driving method are provided in the disclosure. The touch driving circuit includes multiple cascading shifting registers and selection outputting circuits each connected to a respective shifting register. At least one of the selection outputting circuits is connected to multiple touch electrodes; each of the touch electrodes is connected to one of the selection outputting circuits; and when the shifting register is being scanned and the selection outputting circuit connected to the shifting register is connected to multiple touch electrodes, the selection outputting circuit provides touch driving signals with different frequencies for the touch electrodes connected to the selection outputting circuit simultaneously. The touch driving circuit can simultaneously drive multiple touch electrodes to perform touch detections, thus improving the efficiency of the touch detection.
