Abstract: A liquid crystal display driving method is disclosed, where an interlaced image data is received or generated to generate an odd driving signal and an even driving signal, an odd number of gates and an even number of gates are driven according to the odd driving signal and the even driving signal at different signal frame periods, and sources are driven to inverse in their polarities when the driven gates are switched from the ones having the odd number to the even number. Since an alternating number of the sources is reduced, the efficacy of simultaneous promoted power saving and frame quality is achieved.
