Abstract
A driving circuit of a display panel is provided. The display panel includes sensing electrodes. The driving circuit includes a first control unit and a compensation control unit. The first control unit outputs a common voltage or a modulation voltage to the sensing electrodes. The compensation control unit is electrically connected to an input signal line and the first control unit. In a display stage, the compensation control unit generates a first voltage signal according to a feedback signal and an input signal transmitted by the input signal line, and the first control unit outputs the common voltage according to the first voltage signal. In a sensing stage, the compensation control unit generates a second voltage signal according to the input signal, and the first control unit outputs the modulation voltage according to the second voltage signal.
