ABSTRACT:
A gamma reference voltage generator (10B) for an LCD display includes a control interface logic circuit (48) having an output bus coupled to inputs of a first register (46) having outputs coupled to inputs of a second register (42) the outputs of which are coupled to corresponding inputs of plurality of DACs (28). The control interface logic circuit receives gray scale codes representative of gamma reference voltages and transfers the codes via the output bus into the first register and controls further transfer of the codes to inputs of the DACs to instantaneously or rapidly update gamma correction voltages applied to the LCD display.
