Abstract: A source driver capable of improving sensing accuracy even when a black image signal is provided to reduce motion blur during a sensing period for sensing signals of pixels of a display panel, and a display device including the same. The source driver includes an output buffer configured to output a source signal; a voltage terminal applied with a black image signal of a preset voltage level; a source output terminal connected to a data line of a display panel; and a switch circuit configured to connect one of an output terminal of the output buffer and the voltage terminal to the source output terminal, wherein the switch circuit connects the voltage terminal to the source output terminal during a black image insertion period of a sensing period in which a pixel of the display panel is sensed.

Abstract: The present disclosure discloses a source driver capable of accurately sensing characteristics of a display panel by minimizing the influence of a floating channel. The source driver may include normal channels connected to pixels of a display panel, a floating channel under no-load; and a sampling circuit configured to sample signals of the normal channels and the floating channel. The source driver may provide a first reference voltage to the floating channel in a first period in which characteristics of the pixels are sensed.
