Abstract
A method includes outputting a first signal from a first DAC decoder circuit in response to receiving a first number of bits of a digital control signal, outputting a second signal from a second DAC decoder circuit in response to receiving a second number of bits of the digital control signal, and alternately outputting one of the first and second signals to an LCD column from a buffer coupled to the first and second DAC decoder circuits. The first signal has a voltage level equal to one of a first plurality of voltage levels received at one of a first plurality of inputs of the first DAC decoder circuit. The second signal has a voltage level equal to one of a second plurality of voltage levels received at one of a second plurality of inputs of the second DAC decoder circuit.
