摘要： An aspect relates to a display driving device and a method for determining an error of a source amplifier in a display driving device, and determines whether an output buffer (e.g., a source amplifier) provided at an output stage of a display driving device providing data voltage to each pixel (e.g., subpixel) of a display panel has an error to prevent a phenomenon in which a screen is not normally displayed.
