Abstract:
A driving method of a liquid crystal panel which employs a driving signal for periodically driving respective pixels of the liquid crystal panel, comprising the step of:having the driving signal include a compensating signal for compensating for a deficiency of charges with which the respective pixels are supplied at a beginning of respective driving which is repeated periodically; wherein a superimposed wave made up of first and second waves is employed as the driving signal, said first wave being a rectangular wave to be a base of the driving signal, said second wave, to be said compensating signal, capable of increasing respective amplitudes of said first wave in rising and falling directions when said first wave rises and falls, respectively; and wherein when P1 is a charge supply quantity when the liquid crystal panel is supplied with said first wave, and P2 is a charge increase quantity when the liquid crystal panel is supplied with the driving signal, said second wave is set so that the charge increase quantity P2 satisfies ({fraction (1/16)})Ã—P121.
