me Power Management for Modulated Backlights By www.freepatentsonline.com Published On :: Thu, 29 Jun 2017 08:00:00 EDT Power levels of a backlight are adjusted in a number of ways and based on a number of criteria. The adjustments result in a lower power consumption and, in some cases, may enhance audience attention to important objects in a scene. The adjustments comprise, for example, a combination of ramping down power (lowering final display brightness) in concert with corresponding compensatory LCD adjustments (increasing final display brightness). The adjustments may also include, for example, system dimming after ramp down/LCD adjustments are exhausted, or the shifting of an LDR2HDR curve. Full Article
