Abstract

See full text

A data driver for a display includes a reference current generator that is configured to generate L gray scale reference currents, the L gray scale reference currents being associated with non-zero gray scale levels, a gamma selection module that is configured to select M gamma reference currents from the L gray scale reference currents responsive to a gamma signal, a gamma voltage generator that is configured to generate a zero gray scale level gamma reference voltage, and a data current generator that is configured to generate a data current responsive to a selected one of the M gamma reference currents or the zero gray scale level gamma reference voltage responsive to a color signal.
