The column driver for a liquid crystal display (LCD) provides separate analog signals to each color element associated with the pixel. For example, a separate analog signal is provided to a red element, a blue element, and a green element. The driver circuit receives a digital signal representative of the gray scale voltage and provides the analog signal through a switch matrix to each color element. The driver circuit reduces undesirable color shifts as gray scale values are varied.
