Gamma reference voltage generator and display apparatus including the same

A gamma reference voltage generator, comprising:

• a first resistor string configured to receive a first reference voltage and a second reference voltage;
• a plurality of black voltage setters configured to extract a plurality of black candidate voltages from the first resistor string;
• a selector configured to select one of the black candidate voltages as a black gamma voltage based on a selection signal, the selection signal generated based on a black level command signal applied from a host;
• a second resistor string configured to receive a first voltage and a second voltage, the first voltage corresponding to one of the black candidate voltages and the second voltage extracted from the first resistor string;
• and
• a plurality of gamma voltage setters configured to extract a plurality of gamma voltages from the second resistor string.
