Abstract:
A driving-voltage generation apparatus and a liquid crystal display (LCD) having the same are provided. The driving-voltage generation apparatus includes an input node coupled to an input voltage, a voltage converter configured to convert the input voltage into an output voltage and output the output voltage, and a voltage cutoff unit electrically connected between the input node and the voltage converter. The voltage cutoff unit is configured to sense the input voltage and selectively cut off the supply of the input voltage.
