Abstract: A gamma reference voltage generator includes a first resistor string, black voltage setters, a selector, and a second resistor string. The first resistor string receives a first reference voltage and a second reference voltage. The black voltage setters extract a plurality of black candidate voltages from the first resistor string. The selector selects one of the black candidate voltages as a black gamma voltage based on a selection signal. The second resistor string receives a first voltage corresponding to one of the black candidate voltages and a second voltage extracted from the first resistor string. In addition, the gamma reference voltage generator includes gamma voltage setters that extract a plurality of gamma voltages from the second resistor string.

Abstract: A display apparatus includes a plurality of display panels, a power voltage generator and a driving controller. The power voltage generator generates power voltages of the plurality of display panels. The driving controller receives the power voltages from feedback points of the plurality of display panels and generates a control signal and controls levels of the power voltages based on fed-back power voltages from the feedback points of the plurality of display panels. The power voltage generator adjusts the levels of the power voltages and generates compensation power voltages based on the control signal.
