Oppo now uses smaller pixels in the display area around the selfie camera to maintain 400 pixels per inch density on the screen. The earlier version had a different pixel density around the self camera module. Plus, it’s using transparent wiring which is 50% narrower, and provides “ a smoother visual experience.” The company showed off a photo of a device being used as an e-reader with a white background and black text to emphasize that its screen displays pixels consistently from edge to edge. This is due to a one-to-one pixel circuit used in the area around the selfie camera instead of traditional one-to-two pixels. While all this looks pretty cool, we have to keep in mind that all these experiments are done on a prototype device. With real-life usage, there could be many glitches around the selfie module that could make using the phone unpleasant. The company has shared no information if it plans to release a consumer-grade phone featuring this tech. So we don’t really know when this technology will make it to a mainstream device. So far, Xiaomi, Vivo, and Oppo have shown off their work for under-the-screen camera tech only in a demo form. However, only ZTE has released a couple of devices with this feature. So my wait to get hands-on on one of these continues.
