Abstract:
A voltage drop compensation system and a display driving device for compensating for a voltage drop of a display panel. The voltage drop compensation system generates a voltage drop compensation value for each of a plurality of regions into which a test image of a panel is divided, and the display driving device compensates for a voltage drop for each region of image data using the voltage drop compensation value.
