Abstract
An output buffer having a high slew rate, a method of controlling the output buffer, and a display driving device including the output buffer. The output buffer includes: a first output buffer adapted to output a source line driving signal to a first output terminal in response to a first control signal and output a source driving signal to a second output terminal in response to a second control signal; a second output buffer adapted to output a source line driving signal to a third output terminal in response to the first control signal and output a source line driving signal to a fourth output terminal in response to the second control signal; and a feedback circuit for connecting the first through fourth output terminals to negative input terminals of the first and second output buffers in response to the first control signal and the second control signal.
