DISPLAY DRIVER, ELECTROOPTICAL DEVICE, ELECTRONIC EQUIPMENT, AND DRIVING AND SETTING METHOD OF DISPLAY DRIVER

摘要

PROBLEM TO BE SOLVED: To provide a display driver for suppressing abnormality in display caused by clearing set information. SOLUTION: A display driver 100 is provided with an EEPROM142 which stores electronic volume values of an LCD150, a ROM control circuit 140 which reads initial setting information from the EEPROM142 for every prescribed interval and a voltage generating circuit 132 which supplies driving voltages based on the electronic volume values read by the circuit 140.
