  • Patent number: 9812050
    Abstract: A display driving device includes a data driver having a plurality of output drivers configured to output display driving signals. The display driving device also includes an offset adjusting circuit configured to subtract offset voltages generated in the output drivers from an input image signal to generate a corrected image signal. The offset adjusting circuit transmits the corrected image signal to the data driver, so that the data driver outputs the driving signals based on the corrected image signal.
