PURPOSE: A power driver, source driver, and display apparatus are provided to reduce power consumption by using the output voltage of a booster as a gamma voltage for minimum gradation. CONSTITUTION: In a power driver, source driver, and display apparatus, a power driver(1) comprises a plurality of boosters and a plurality of amplifiers. A plurality of amplifiers are turned off when the display apparatus is a standby mode. A plurality of boosters(10-1~10-3) comprise first to third boosters. A plurality of amplifiers(11-1~11-3,12-1~12-a) comprises first to third amplifier which are connected to the output terminal of the first to third booster and also includes a plurality of gamma amplifiers. The output voltage of the first booster is used as the minimum gradation data gamma voltage. |
