Apple has recently secured approval from the U.S. Patent and Trademark Office for patent number 17/715,343, titled "Electronic Device with Edge Illuminator." This patent unveils an innovative design for Apple's smart ring, which incorporates a micro LED or OLED one-dimensional pixel array around the ring's edge, creating a subtle, low-resolution halo effect. The primary objective of this design is to discreetly convey notifications such as incoming calls, schedule reminders, or health alerts, without disrupting the user's ongoing activities. Additionally, the smart ring offers haptic feedback for an enhanced user experience.
