DRIVING CIRCUIT AND A METHOD FOR DRIVING A DISPLAY PANEL HAVING A TOUCH PANEL

摘要

A driving circuit configured to drive a display panel having a touch panel is provided. The driving circuit includes a signal generating circuit, a sensor driving circuit, and a source driving circuit. The signal generating circuit modulates a plurality of voltage signals on a first driving signal and a second driving signal, and drives the gate lines with the modulated first driving signal and the modulated second driving signal during a sensing period. The sensor driving circuit modulates the voltage signals on a third driving signal, and drives the sensor pads with the modulated third driving signal during the sensing period. The data lines are controlled to be electrically floating during the sensing period. In addition, a method for driving a display panel having a touch panel is also provided.
