Provided is a touch driving method for a touch display device. The touch display device includes a display panel and a touch panel. The touch panel is disposed on the display panel. The touch panel includes a first driving electrode and a second driving electrode. The touch driving method includes: a first touch driving signal is provided to the first driving electrode, and a second touch driving signal is provided to the second driving electrode; a sum of a voltage value of the first touch driving signal and a voltage value of the second touch driving signal is adjusted to continue to be equal to a set voltage value in a mutual-capacitance sensing stage of a mutual-capacitance sensing mode; and the first touch driving signal and the second touch driving signal are adjusted to be a third touch driving signal in a self-capacitance sensing stage of a self-capacitance sensing mode.

Touch driving method with set sum of touch driving signals to reduce flicker on display device

A touch sensing reading device includes an operation circuit and an adjustment circuit. The operation circuit includes a feedback capacitor, receives a sensing signal through a first input terminal, receives a driving signal through a second input terminal, and feedbacks an output signal via an output terminal through the feedback capacitor and the first input terminal. The adjustment circuit provides an adjustment signal to the first input terminal of the operation circuit, and adjusts the output signal. A first sub-signal in the adjustment signal is set based on the inverted signal of the driving signal. A second sub-signal in the adjustment signal is set based on the inverted signal of the sensing signal.
