Abstract
A data driver IC can include an analog-to-digital converter; a sensing part that, in a sensing mode for sensing the driving characteristics of pixels, samples a signal outputted from the pixels in response to a data voltage for sensing, and, in a calibration mode for sensing the output characteristics of the analog-to-digital converter, samples a calibration current and outputs the same to the analog-to-digital converter; and a current generator that generates N calibration currents by dividing an external input source current into N parts, where N is a natural number.
