Abstract
A driving device for liquid crystal panel comprising: a scanning driver for applying a scanning voltage to pixels arranged as a matrix row by row; and a data driver for receiving an image data and a polarity inversion signal, obtaining original data voltages according to the image data, determining if amplifying the original data voltages along a scanning direction according to the polarity inversion signal, and providing the original data voltages or data voltage after being amplified to pixels. A driving method is also disclosed. When polarity inversion signal is inverted to a positive polarity from a negative polarity, the data voltages applied on the data line are gradually increased along a scanning direction. Accordingly, when the polarity inversion signal is inverted to a negative polarity from a positive polarity, the pixel which leaks current seriously is charged with a larger amount of charges, uneven display brightness is obviously decreased.
