How does it work?
The technology uses an ultra-thin transparent material and a new pixel structure sitting above the camera, which allows light to pass through the glass and into the lens when not in use. Oppo says a wider aperture and sensor are needed to capture enough light after being filtered through the layer. As bigger and higher-resolution sensors become more popular, this shouldn’t be a problem for long. During my time with the prototype, the selfie quality looked great.
With the wrong color wallpaper at the wrong angle, it’s definitely possible to see the camera housing, which is currently taking a strange square shape. In most conditions though, the cutout is almost completely hidden, and frankly, that’s amazing.
While I can’t wait for this technology to make its way to the mainstream, I’m really excited for everyone to finally stop arguing about notches.
