Abstract

A voltage conversion circuit and a display device are provided. The voltage conversion circuit includes a voltage conversion module, a comparison module, and a control module. The voltage conversion module includes at least two voltage conversion units, and the voltage conversion unit converts the input voltage into a target voltage. The comparison module compares each of testing voltages with a reference voltage to generate a feedback signal. The control module receives the feedback signal and controls the voltage conversion unit to convert the input voltage to the target voltage based on the feedback signal.
