Abstract: A pixel of a transflective liquid crystal display panel having a controllable backlight comprises an array of sub-pixels and a color substrate with an array of colors corresponding to the array of sub-pixels, the array of colors comprising transmissive colors and reflective colors. The color substrate transmits at least one wavelength of light corresponding to the transmissive colors in the array of colors when the controllable backlight emits a first predetermined light level and, from substantially the same area in the color substrate, reflects at least one wavelength of light corresponding to the reflective colors in the array of colors when the controllable backlight emits a second predetermined light level. The transmissive colors may be primary or secondary colors, and the reflective colors may be primary or secondary colors.
