The latest SmartPower HDR technology modifies the voltage to prevent laptop displays from using up your battery needlessly.
Samsung Display and Intel have collaborated on laptop technology known as SmartPower HDR, which they assert can reduce power consumption while viewing HDR content on an OLED display. Intel showcased this technology last year, but Samsung Display is providing insights into its functionality and the potential power savings. However, the firm has not specified which laptops will feature SmartPower HDR, leaving the timeline for when it will be available on consumer devices uncertain.
With SmartPower HDR, Samsung Display states that the laptop’s chipset tracks the peak brightness of each frame it renders in real-time. Subsequently, the OLED panel’s timing controller uses that information along with the active pixels’ ratio to determine the optimal driving voltage for the panel.
Samsung Display:
For instance, typical laptop tasks like web browsing or document editing can run at reduced voltage levels. Conversely, high-definition content such as gaming or video playback demands increased brightness and voltage. Conventional HDR modes remain locked at peak brightness, resulting in excessive power usage even in regular situations. Consequently, many laptops default to SDR (Standard Dynamic Range) mode despite the visual and brightness benefits of HDR.
In contrast, SmartPower HDR™ can cut down power consumption associated with OLED pixel emission by up to 22% in normal usage and by up to 17% when displaying HDR content. Remarkably, under typical usage scenarios, power consumption parallels that of SDR mode.
