Patent ID: 8232985

Claim:
A display driving circuit, comprising: a first voltage generation unit, a second voltage generation unit, and a third voltage generation unit, the voltage generation units being connected to each other and configured to: receive an externally applied input voltage having a same magnitude; and generate respective voltages having different magnitudes, the second voltage generation unit being configured to: receive source voltages generated by the first and third voltage generation units; and output a high driving voltage and a low driving voltage; and a latch-up prevention unit connected to the second voltage generation unit, the latch-up prevention unit comprising a control logic unit configured to output a control signal that is used to control a supply of the low driving voltage, the latch-up prevention unit being configured to: receive the low driving voltage from the second voltage generation unit; and ground the low driving voltage for a preset period of time, wherein the control signal is output by the control logic unit when the second voltage generation unit has not received the source voltages generated by the first and third voltage generation units, thereby grounding the low driving voltage for the preset period of time.
