Hidden feature of Samsung Galaxy S24 series phones: dimming non-HDR elements to improve user experience

According to news on January 19, Samsung officially launched the Galaxy S24 series of mobile phones at the Galaxy Unpacked conference that opened early yesterday morning, focusing on integrating many Galaxy AI functions and also introducing Super HDR.

Source Mishaal Rahman recently tweeted that Samsung has also introduced SDR dimming (SDR dimming) function for the Galaxy S24 series mobile phones, dynamically adjusting the standard dynamic range (SDR) and high dynamic range ( HDR) elements to improve the viewing experience of mixed content. Note: SDR dimming is a software-based technology that selectively adjusts the brightness of SDR elements displayed on an HDR screen. For example, the notification shade or app interface in an HDR video can be subtly dimmed, while the video itself maintains full HDR brightness and contrast. Samsung Galaxy S24 leverages Android 14’s new system APIs to identify and adjust the brightness of individual pixels in display content. This approach allows for a more precise and subtle dimming effect compared to previous methods of simply reducing overall screen brightness. SDR Dimming is a technology that dims SDR elements while maintaining HDR highlights; it creates a more visually balanced and consistent viewing experience. In addition, by selectively dimming pixels, SDR dimming can also slightly reduce power consumption when mixed content is played back. In low-light environments, the low brightness of non-HDR elements can reduce eye fatigue while improving the clarity of text and other user interface elements.
