Abstract
A power supply circuit has a first voltage converter and a second voltage converter. The first voltage converter generates a first power supply voltage having a first voltage level based on an input voltage. The first power supply voltage drives a first power node of a display in a first mode. The second voltage converter generates a second power supply voltage having a second voltage level based on the input voltage. The second power node is driven by the second power supply voltage in the first mode and is driven by a ground voltage in a second mode.
