Zusammenfassung:	Techniques for display contrast enhancement are disclosed. In an illustrative embodiment, an ambient light sensor determines an amount of ambient light in the environment of the compute device. The display of the compute device has a reflectivity that causes some of the ambient light to be reflected off of the display. The reflected ambient light reduces the contrast ratio of the display. In order to compensate, the compute device can increase the brightness of the backlight based on the reflectivity of the display. In this manner, the compute device can adjust the contrast, such as by achieving a certain target ambient contrast ratio, based on the reflectivity of the display and without unnecessarily increasing the brightness of the backlight, conserving power. This approach can be used with other contrast-enhancing and/or power-saving algorithms, such as localized adaptive contrast enhancement (LACE) and/or display power savings technology (DPST).
