The device is capable of activating at least two color LEDs simultaneously, thus obtaining additional display colors. A method is disclosed for displaying more than three colors using an LCD device having three color LEDs, in which the LED back illumination system sequentially illuminates the LC array with only a first single LED color, a simultaneous operation of first and second LED colors, and then only the second LED color. The device may drive the LC cells from a first color data value directly to a subsequent color data value directly, without driving the LC cell to zero transmittance prior to loading of the subsequent color data value. The device may correct for color phase shift and for the dependency of apparent color intensity.
