Abstract
The present disclosure, in an aspect, relates to a source driver to control a bias current, and more particularly, to a source driver, in which a bias current of a buffer is controlled depending on a distance between the source driver and a pixel in a data line and a position, regarding which a bias current is set, and the intensity of the bias current are changed in every frame so that unnecessary power consumption due to bias currents may be reduced and a block-dim phenomenon may be alleviated.
