发明名称 Display driving apparatus and driving control method
摘要 A display driving apparatus includes common electrode reverse section for reversing a potential of a common electrode of an active matrix liquid crystal display panel for each predetermined period, and gradation reference voltage setting section for setting minimum and maximum gradation reference voltages based on a contrast set value and correction voltage set value, every time the potential of the common electrode is reversed and for setting one of fluctuation center voltages of the gradation reference voltages, by which a smaller voltage is applied to liquid crystal display pixels, such that one voltage is higher than the other by a voltage corresponding to the correction voltage set value.
