Oppo has introduced a novel concept called "Bubble" that involves a thin, round screen mounted on the back of a smartphone. This secondary display is designed for taking selfies using the rear camera, which typically offers higher quality than front-facing cameras.
The Bubble screen is a small, circular touch display that can be attached or integrated into the phone's back panel. When activated, it shows a live preview from the rear camera, allowing users to frame and capture selfies with the main camera. This concept leverages the superior lenses and sensors found on the back of modern smartphones.
While still a concept, the Bubble highlights Oppo's focus on innovation in mobile photography. The round shape is reminiscent of smartwatch screens, but here it serves a unique photographic purpose. There is no word yet on whether Oppo plans to mass-produce this design.
This approach avoids the compromises often seen in front-facing cameras, such as lower resolution or under-display technology, while still offering a practical selfie experience.
