Abstract:
A display driving circuit is provided. The display driving circuit includes first to third voltage generation units configured to receive an externally applied input voltage having a same magnitude and generate respective voltages having different magnitudes, and a latch-up prevention unit connected to the second voltage generation unit and configured to receive a lower voltage among voltages output from the second voltage generation unit and to ground the lower voltage for a preset period of time.
