A method and apparatus for gray level dynamic switching. The method is applied to driving a display with at least one pixel. In the method of the present invention, a gray level sequence SG is provided. SG sequentially represents two or more desired gray levels GO(1), . . . , GO(T) of the pixel at consecutive time frames 1, . . . , T and comprises a-current gray level Go(t) and a previous gray level GO(t-1) corresponding to time frames t and t-1, respectively. Then, the pixel is driven with an optimized driving force Vd(t) to change the forward pixel to a state corresponding to Go(t)according to Go(t) and GO(t-1) In the present invention, the optimized driving voltage Vd(t) is determined by equations of Vd(t)=Vo(t-1)+ODV and Vd(t)=axGd(m)<3>+bxGd(m)<2>+CxGd(m)+d wherein the voltage ODV is a minimum voltage capable of obtaining one gray level transition in a determined response time.
