ABSTRACT:
A display driver, an electro-optical device, and a display driving method are provided that can regulate output voltages with high precision and without reducing reliability. The display driver includes an electronic volume value generating circuit that generates an electronic volume value for regulating output voltages, a power supply circuit that generates output voltages using a standard voltage amended based on the electronic volume value, a driving circuit that drives the electro-optical element based on the output voltages corresponding to display data, and an absolute value setting register for setting an electronic volume absolute value. The driving circuit uses an amendment value corresponding to a difference between a given characteristic value set in accordance with the electro-optical element being driven and a center value of a range that can be taken by the electronic volume value to amend the electronic volume absolute value, thereby generating the electronic volume value.
