Abstract
A display driver integrated circuit comprising an operational amplifier configured to amplify an input voltage and generate an output voltage and a slew rate control circuit configured to generate a compensation current based on a difference between the input voltage and the output voltage and provide the generated compensation current to the operational amplifier, wherein the slew rate control circuit comprises a comparison circuit configured to compare the input voltage and the output voltage and generate a difference current corresponding to a difference between the input voltage and the output voltage, a pull-down circuit comprising a pull-down transistor group and configured to generate a pull-down compensation current by current-mirroring the generated difference current, and a pull-up circuit comprising a pull-up transistor group and configured to generate a pull-up compensation current by current-mirroring the generated difference current is provided.
