ABSTRACT:
A source driver includes an output buffer for outputting a driving signal; a first current path coupled between the output buffer and a data line; and a second current path coupled in parallel to the first current path. During a first driving period, the output buffer utilizes both the first current path and the second current path to drive the data line. During a second driving period, the output buffer utilizes only the first current path to transmit the driving signal so as to improve the stability of the source driver.
