Samsung patents method to adjust AOD brightness based on color values

Patent drawing
Patent drawing from the official filing.

Samsung describes a method for adjusting the brightness of an always-on display (AOD) by analyzing the specific colors shown on the screen. The system detects the surrounding light level and compares the brightest color value in the content against a reference table to calculate how much to dim or brighten the red, green, and blue channels. This allows the display to adjust its output based on both the environment and the specific image being shown.

Why it mattersThis could help phones manage battery life more efficiently by fine-tuning screen brightness for the specific content displayed during the always-on mode.

In the filing’s own words

An electronic device and a method for controlling the brightness of always on display content, and a storage medium are provided. The method includes detecting ambient illuminance, identifying a maximum value among a red (R) value, a green (G) value, and a blue (B) value of the content, acquiring a difference value by comparing an RGB-value of a reference table corresponding to the detected ambient illuminance with the identified maximum value, adjusting the R value, the G value, and the B value of the content based on the acquired difference value, and displaying the content, the R-value, the G-value, and the B-value of which have been adjusted, as the always on display content on a display.

What exactly they claim (claim 1)

1. A method for controlling brightness of always-on-display content, the method comprising: detecting ambient illuminance; identifying a maximum value among a red (R) value, a green (G) value, and a blue (B) value of content; acquiring a difference value by comparing an RGB value of a reference table corresponding to the detected ambient illuminance with the identified maximum value; adjusting the R value, the G value, and the B value of the content, based on the acquired difference value; and displaying the content, the R value, the G value, and the B value of which have been adjusted, as the always-on-display content on a display.
