Samsung Display and Intel have co-developed a new technology for OLED laptops, dubbed "SmartPower HDR," and it's exactly what it sounds like. Unlike traditional HDR-capable displays that keep the panel running at a fixed high voltage to account for brightness spikes, SmartPower HDR will dynamically adjust power to the panel, resulting in up to 22% decreases in battery consumption.
SPHDR will analyze the peak luminance of each frame, ensuring that the voltage remains as low as possible until the content calls for a sudden burst in brightness — only then will the display ramp up to provide the necessary juice. Even in peak brightness scenarios, compared to the regular HDR mode, SPHDR should consume a bit less power without affecting the actual brightness.
