Drive method of an electro optical device, a drive circuit and an electro optical device and an electronic apparatus

A drive circuit for an electro optical device including display portion having pixels arranged in a matrix with electro optical material of which an optical transmittance ratio is changed by applying voltage, supplying on-voltage for making the transmittance ratio be saturated, or off-voltage for making the transmittance ratio be an non-transmissive to the display portion and implementing sub field drive to realize a gray scale in response to the ratio of optical transmissive state to a non-transmissive state of the electro optical material per unit time and time ratio;

• comprising;
• a data conversion means for placing emphasis on responsiveness, driving each of the pixels with each sub field as a control unit, that is formed by dividing a field into plural portions on a time axis, and designating a sub field of applying the off-voltage and a sub field of applying the on-voltage in response to display data;
• and
• a data conversion means for placing emphasis on gray-scale reproductiveness, driving each of the pixels with the sub field as a control unit and designating a sub field of applying the off-voltage and a sub field of applying the on-voltage in response to the display data so that levels of gray scale are larger than that of the data conversion means for placing emphasis on responsiveness.
