Abstract
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.
