Abstract

Disclosed are a source driver and a method of detecting crack of a display panel. A source driver may comprise a first circuit configured to apply first data to data lines connected to sub-pixels of a display panel to charge a first driving voltage; and a second circuit formed on the display panel that applies the first driving voltage to a detection line formed on the display panel to detect the presence of cracks in the display panel based on the illumination status of the sub-pixels, wherein the detection line includes a first detection node and a second detection node formed on one side of the display panel along its extension direction, wherein the first detection node is connected to data lines of the first and third sub-pixels, and wherein the second detection node is connected to data line of the second sub-pixel.
