Oppo shows off a working prototype of its under-display selfie camera

The quest for a bezel-less smartphone has led tech companies to try out a variety of technologies aimed at circumventing the need for allocating space for the selfie camera and other assorted sensors on the front of the device. This initially led to the introduction of notches on smartphones and has recently culminated in sliding and rotating camera implementations.

The simplest and most efficient solution, as far as eliminating moving parts is concerned, is one Oppo recently showed off on Twitter: an in-display camera. The video shows a nearly all-screen smartphone lying on a table with no notch or punch-hole cutout for the front camera. Yet, when the camera app is opened, there"s a black bar at the top end of the screen, and the demonstrator"s finger in front of the phone can clearly be seen being captured by the under-display front camera.
