Abstract
A driving method, a driving circuit and a touch-display apparatus are provided. The driving method includes providing a gate driving signal to a gate line, providing a pixel voltage to a data line, and providing a common electrode driving signal to a common electrode, wherein a pixel display operation is performed based on the gate driving signal, the pixel voltage, and the common electrode driving signal, and simultaneously, a touch detection operation is performed based on the common electrode driving signal. The driving method realizes the effect of simultaneously performing a pixel display operation and a touch detection operation, and solves the problem that the pixel display operation of the touch-display apparatus is affected in the touch detection stage.
