Abstract
A power supply and a display device using the same are provided. The power supply includes a logic voltage generator and a power voltage generator. The logic voltage generator generates an internal logic voltage based on an externally input voltage. The power voltage generator generates a plurality of power voltages based on the external input voltage. When the external input voltage is cut off, the power voltage generator stops outputting a drain voltage, and then stops outputting a half drain voltage.
