    摘要： In a first embodiment, a display system comprises a display panel with 4 or more colored subpixels. The display system receives input image data specified in a first color space and outputs image data specified in a second color space. The display system further comprises a gamut mapping module for mapping the input image data specified in the first color space to image data specified in the second color space. The gamut mapping module clamps out-of-gamut colors using at least a first clamping system and a second clamping system. The first and second clamping systems yield first and second clamped values. A weighting module produces a resulting clamped value from the first and second clamped values. A final output image value is derived from the resulting clamped value. Other embodiments of the display system include pre-reduction modules and adjustable GMA modules.

    摘要： Displays systems and methods for adjusting backlight illumination are disclosed wherein backlight illumination may be set low enough according to an error threshold amount in order to reduce backlight power consumption while maintaining a level of image quality. In one embodiment, image data is evaluated within a given frame and partitioned into histogram bins depending on the amount of backlight illumination requested or required by the image data. The histogram is traversed to provide an accumulative error measure. The error measure is compared against the error threshold and, if exceeded, the final backlight illumination may be set as a function of various illumination levels considered and possibly the first and a second threshold.
