Abstract:
A gray scale voltage generator includes a voltage dividing resistor string to generate blue (B), red (R), and green (G) gamma voltage signals, the voltage dividing resistor string including a B gamma voltage signal generating section, a R/G gamma voltage generating section, and a common (COM) gamma voltage generating section to individually control a B gray scale voltage and a R/G gray scale voltage to maintain a constant color temperature.
