Beijing, Dec 4 : Chinese smartphone maker Vivo is reportedly working on a new phone with an extendable display similar to the OPPO X 2021 rollable phone. The patent was published on December 2 and contains images of the sliding concept, reports GizmoChina. According to the patent drawings, the phone will have an extendable screen that expands from the right to enlarge the display to fit in more content, thanks to the additional screen real estate. The phone will come with a triple camera module that can be observed on the left side of the phone, which appears when the screen is extended. The speaker grille can be observed on the top, while the USB Type-C port is on the right. Vivo has also patented a smartphone with a detachable under-display selfie camera module. This detachable camera module will slot into one of the top corners of the smartphone, allowing it to be seamless with the body without any visible bulge. The device will offer a full front screen experience with or without this module being attached to it, it added. Under display, camera technology is already a reality and has been available in the commercial market for a while now. The patent is quite detailed with schematics revealing a release mechanism that allows users to detach the camera unit. /IANS
