<p>A gamma voltage generator (60) capable of displaying linear gray levels at low gray levels. The gamma voltage generator (60) includes a ladder resistor (61) positioned between an uppermost voltage (VH1) and a lowermost voltage (VLO) to output a plurality of voltages, a first gray level voltage selector (64) for outputting one of some voltage values supplied from the ladder resistor as a first gray level voltage, a minimum voltage selector (65) for outputting one of remaining voltage values supplied from the ladder resistor as a minimum voltage that displays a brightest gray level; intermediate voltage selectors (66-69) for outputting respective intermediate gray level voltages, and a gray level voltage output unit (70) for generating gamma voltages required for generation of data signals using the first gray level voltage, the minimum voltage, and the intermediate gray level voltages.</p> |
