Abstract:
A display driving device is disclosed which includes a source driver that supplies voltages to source lines connected to pixels, detects a slew time of the voltages of the source lines, and outputs the slew time, and a timing controller that receives the slew time from the source driver and updates a way for the source driver to control the voltages depending on the slew time.
