Zusammenfassung:This invention relates to the field of display systems, more particularly to sequential color display systems. A display system () and method for increasing the brightness of an image through the use of a color wheel () having white light generating segment. The display system comprises a RGBW processing function (), a hue correction function (), and a gain correction function (). The RGBW processing function () includes circuitry to generate an intensity word for use during the white light generating segment. The hue correction function () includes circuitry to adjust the relative intensities of the primary color components to compensate for the addition of the white segment data. The gain correction function () includes circuitry to adjust the intensity of pixel data based on the white content of the pixel and the intensity of the pixel. After the pixel data is processed, it is formatted by data formatting logic () and displayed using a spatial light modulator ().
