ABSTRACT:
The present invention aims at providing a display driver and a display device using such a display driver which can prevent the deterioration of the display quality of a display section by suppressing the drop of a power source voltage between respective display drivers. When a COG-mounted liquid crystal display panel whose mode can be changed over between a master mode and a slave mode is driven by a plurality of display drivers, the display driver at the master side which is set in the master mode supplies the power source voltages for driving liquid crystal generated by a voltage generating part due to input switching parts to power source voltage input terminals of the display driver at the slave side using operational amplifiers. The display driver at the slave side generates the power source voltage for driving the liquid crystal from the power source voltage supplied from the power source voltage input terminals by input switching parts using the voltage-follower connected operational amplifiers.
