Abstract:
Provided is an output amplifier including a differential unit which sends a current corresponding to a voltage difference between a gradation voltage and an amplified gradation voltage to a first current line; a current mirror unit which sends an amount of current corresponding to the current flowing through the first current line, to a second current line; and an output unit including a first and a second drive line, an output line through which the amplified gradation voltage is output, a first output transistor which sends a current based on a voltage of the first drive line, and a second output transistor which sends a current based on a voltage of the second drive line. The output unit includes a voltage regulation circuit which controls the voltage of the first drive line being higher than the voltage of the second drive line.

Claim (Index 6):
A display driver comprising a plurality of output amplifiers configured to amplify gradation voltages supplied there to, so as to generate amplified gradation voltages, wherein\n said plurality of output amplifiers are constituted of a first output amplifier group and a second output amplifier group, each of said output amplifiers belonging to said first output amplifier group and said second output amplifier group includes:\n a differential unit configured to send a current corresponding to a voltage difference between said gradation voltage and said amplified gradation voltage to a first current line; \n a current mirror unit connected between a first voltage supply line to which a first voltage is supplied and a second voltage supply line to which a second voltage lower than said first voltage is supplied, the current mirror unit being configured to send a current to the second current line by an amount corresponding to an amount of the current flowing through said first current line; and \n an output unit including first and second drive lines respectively connected to said second current line, an output line through which said amplified gradation voltage is output, a first output transistor configured to send a current based on a voltage of said first drive line to said output line, and a second output transistor configured to send a current based on a voltage of said second drive line to said output line, \n said output unit of each of said output amplifiers belonging to said first output amplifier group includes a first voltage regulation circuit configured to control the voltage of said first drive line such that the voltage of said first drive line is higher than the voltage of said second drive line, and said output unit of each of said output amplifiers belonging to said second output amplifier group includes a second voltage regulation circuit configured to control the voltage of said second drive line such that the voltage of said second drive line is lower than the voltage of said first drive line.
