Abstract
A touch and display driving circuit applicable to driving at least one sensing pad of a touch and display panel and its operation method thereof are provided. The touch and display driving circuit includes a source driver circuit and a touch circuit having an analog front-end circuit, being electrically coupled to the sensing pad of the touch and display panel. The source driver circuit is operable and connected with a first operational voltage and a second operational voltage. The analog front-end circuit is operable and connected with a third operational voltage and a fourth operational voltage. The first operational voltage and the second operational voltage of the source driver circuit are different from the third operational voltage and the fourth operational voltage of the analog front-end circuit. By employing the disclosed technical contents, the invention is effective in reducing power consumption and redundant power waste.
