PROBLEM TO BE SOLVED: To provide a display driver capable of adjusting an output voltage with high accuracy without lowering reliability, and to provide an optoelectronic device and a display driving method.;SOLUTION: This display driver 20 includes an electronic volume value creating circuit 50 creating an electronic volume value for adjusting the output voltage; a power source circuit 40 creating the output voltage using a corrected reference voltage corrected based on the electronic volume value; a driving circuit 60 driving an electro-optical element based on the output voltage corresponding to display data; and an absolute value setting register 94 for setting an electronic volume absolute value. The circuit 60 creates the electronic volume value by correcting the electronic volume absolute value using the corrected value corresponding to a deviation between a given characteristic value set according to a driving object and a center value in a range the electronic volume can take.;COPYRIGHT: (C)2004,JPO&NCIPI
