Abstract
The present disclosure discloses a precharge circuit capable of compensating for a resistance deviation between channels so that sense lines of a display panel can be uniformly charged and a source driver including the same. The precharge circuit may include a voltage terminal configured to provide a reference voltage, a common line connected to the voltage terminal, and channel lines connected to the common line and configured to transfer, to respective sense lines of a display panel, the reference voltage transferred through the common line.
