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.

Abstract: A touch display device and an improvement method to a touch display device are disclosed. The improvement method first determines whether the touch display device turns on the touch mode. If yes, image data input to the touch display device is obtained and feature data is extracted from the image data. Then, adjustment or compensation factors are obtained according to the feature data. Grey level compensation sequence is also obtained. The duty cycle of the control signal for the touch display device is adjusted according to the factors and the grey level compensation sequence, so as to improve the display difference for a same grey level image due to the turning on of the touch mode.
