Abstract
A driving method for a liquid crystal panel is disclosed. Wherein, the driving method includes: (A) at a moment of switching from a normal display time stage to a touch scanning time stage in a current frame, applying a first over driving voltage to a common electrode of each pixel of a liquid crystal panel; and (B) at a moment of switching from the touch scanning time stage in the current frame to a normal display time stage of a next frame, applying a second over driving voltage to the common electrode of each pixel. According to the method described above a time that the common electrode reaches a present level voltage is shorten in order to effectively improve the poor display and touch problem caused by signal abnormality at moments of switching between a normal display and a touch scanning in an in-cell touch panel.
