ABSTRACT:
A boosted voltage generator for increasing boosting efficiency according to the amount of load and display apparatus including the same are provided. The boosted voltage generator includes an input voltage generator configured to generate a first input voltage or a second input voltage based on a reference voltage, compare the reference voltage with a feedback boosted voltage fed back based on the amount of load at an output terminal, and output a comparison result; and a booster configured to boost the first or second input voltage using at least one external capacitor based on the comparison result and output a boosting result as a boosted voltage to the output terminal. The boosted voltage generator and the display apparatus including the same can increase the boosting efficiency according to the amount of load.
