A white-light-emitting electroluminescent device includes light-emitting elements for emitting different colors of light, wherein one of the light-emitting elements has a luminous efficacy greater than the luminous efficacy of at least one of the other light-emitting elements. The different colors of light combine to form white light. Also included is a driver for receiving a color signal representing a relative luminance and color produced by the electroluminescent device. The driver is responsive to a converted control signal when controlling the color accuracy of the light produced by the light-emitting elements to ultimately reduce the power consumption of the white light-emitting electroluminescent device.
