摘要： 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.

摘要： A stylus pen that includes a tip electrode, a power supply circuit, a signal detector, and a drive circuit where an output signal is transmitted to and an input signal is received from a touch panel via the tip electrode. The power supply circuit of the stylus pen selectively supplies a first supply voltage or a second supply voltage. The signal detector of the stylus pen detects an enable signal from the input signal and the signal detector of the stylus pen controls the power supply circuit to supply the first supply voltage in response to presence of the enable signal. The drive circuit operates at the first supply voltage to generate the output signal.
