Oppo has showcased its next-gen under-display camera (UDC) technology. It is working on the tech since 2019 when it unveiled its first-generation offering. It did not make its way to any commercial smartphone but with the latest iteration, the team has some noticeable improvements and we might see it commercially this time around.
The announcement reveals that the newest UDC tech brings improved selfie camera performance while delivering consistent display quality. All these improvements are the result of several innovations that the team has implemented. The first thing to note is that the size of each pixel has been reduced without decreasing the total number of pixels. It means the new tech offers high-quality 440PPI pixel density even around the selfie camera display area.
The next major difference is that Oppo has opted for transparent screen wiring instead of the traditionally used wiring. It is claimed to be 50% thinner and yet capable of providing the same level of display experience as many of the best Android smartphones. The team has further used each pixel circuit for powering just one pixel instead of powering two pixels.
Oppo is not the only one working on the under-display camera tech. ZTE is another OEM and it has even released smartphones Axon 20 and Axon 30 featuring its first-gen and second-gen tech respectively. The main aim behind developing the tech is to deliver a full-screen experience with no thick bezels or even a punch-hole. Many OEMs have even tried the pop-up selfie camera approach but people have had their fair share of doubts about its durability and longevity.
