Patent ID: 7265495

Claim:
A display driver for driving a pixel comprising: a first transistor of a first conductive type; a first reference transistor of the first conductive type constituting a current mirror with the first transistor; a second reference transistor of the first conductive type constituting a current mirror with the first transistor; a first current transistor of a second conductive type electrically connected to the first reference transistor and receiving a reference current from the first reference transistor or supplying a reference current to the first reference transistor; a second current transistor of the second conductive type electrically connected to the second reference transistor and receiving a reference current from the second reference transistor or supplying a reference current to the second reference transistor; a plurality of mirroring transistors of the second conductive type, gate electrodes of the plurality of mirroring transistors electrically connected to each other and electrically connected to both a gate electrode of the first current transistor and a gate electrode of the second current transistor; and an output circuit electrically connected to the plurality of mirroring transistors and capable of driving a wire connected to the pixel in response to an input digital data.
