A method for avoiding an image sticking effect includes acquiring a color tone status of an image during a predetermined time interval according to an input signal of a liquid crystal display panel, rotating pixel molecules of at least one region of a plurality of regions of the image by using a pixel inversion process when the color tone status is maintained at a steady state, and after the pixel molecules of the at least one region of the image are rotated, suspending the pixel inversion process of the image when the color tone status is changed from the steady state to an unstable state.
