The latest SmartPower HDR technology modifies the voltage to prevent laptop displays from excessively draining your battery.
Samsung Display and Intel have collaborated on laptop technology referred to as SmartPower HDR, which they assert can reduce energy consumption while viewing HDR content on an OLED display. Intel demonstrated this technology the previous year, but Samsung Display is now providing insights on its functionality and the potential power savings. Nonetheless, the company did not disclose which laptops will feature SmartPower HDR, leaving it unclear when it will be available in actual laptops.
With SmartPower HDR, Samsung Display indicates that the laptop’s chipset assesses the maximum brightness of each frame in real-time. Subsequently, the timing controller chip of the OLED panel employs that information together with the ratio of active pixels to determine the ideal driving voltage for the panel.
Samsung Display:
For instance, typical laptop functions such as browsing the web or editing documents can run at lower voltage settings. Conversely, high-definition tasks like gaming or video playback demand higher brightness and voltage levels. Conventional HDR modes remain fixed at peak brightness, causing excessive energy consumption even in standard applications. Consequently, numerous laptops revert to SDR (Standard Dynamic Range) mode despite HDR’s advantages in color and brightness.
In contrast, SmartPower HDR™ can cut power use linked to OLED pixel emissions by up to 22% during routine use and by up to 17% when watching HDR content. Importantly, in general use cases, power usage is on par with that of SDR mode.
