Method for Eliminating/Reducing Image Sticking of In-cell Touch Display and Mobile Device Using the Same

Abstract

A method for eliminating image sticking of an in-cell touch display and a mobile device using the same are provided. The method comprises the steps of: providing at least a first common electrode and a second common electrode in the in-cell touch display to perform touch sensing, wherein the first common electrode is electrically connected to a first pin of a touch control circuit through a first charge/discharge route, the second common electrode is electrically connected to a second pin of the touch control circuit through a second charge/discharge route; and in a time except for display time, controlling the first pin and the second pin so that a voltage of the first pin is higher than a voltage of the second pin for at least a first preset period, and then controlling the first pin and the second pin so that a voltage of the second pin is higher than the voltage of the first pin for at least the first preset period.
