OPPO announced on the 13th，It will be on November 17, 2020- 18OPPO Future Technology Conference 2020 was held in Shenzhen on the same day (OPPO INNO DAY 2020)。By then，OPPO Vice President Liu Chang will showcase 3 concept products and 2 sets of technology systems。In addition to the AR glasses that have been confirmed to be unveiled, it is also possible to disclose information about the under-screen front lens and foldable device.。
Rumors，A foldable foldable inside the screen is being developed internally；Now another new mobile phone patent has been exposed。The patent was submitted to the National Intellectual Property Office (CNIPA) at the end of April this year，It was officially approved on November 13，28 design sketches included in the patent，Showcase this unique Oppo smartphone from every angle。
What's unique about this foldable phone is that it can zoom in on the screen by stretching the phone。When stretching up，The upper part will move with it，This way, even if the screen is stretched，It will also be protected by the shell on all sides，This will undoubtedly enhance its durability。In fully expanded state，The screen area is 1.5 times the folded state。
No selfie camera is seen in the patent image，It is estimated that OPPO will put it under the screen。Second half of last year，Oppo has shown a smartphone with a camera under the screen。It was mentioned at that time，Image quality is not enough for commercial products。
Although there is no mobile phone equipped with under-screen camera yet, it is launched，But this technology is still under further development in the background。Presumably，The new generation of display in-screen selfie camera technology will also be discussed during INNO Day 2020。
on the back of the fuselage，There is a camera on the upper part，When the screen is pulled out，This camera will move with the upper frame。correct，It's very likely that Oppo decided to combine several adjacent rear cameras in the final design。
but，At present, the technology of folding screens or reel screens has not yet truly achieved technological maturity and mass production.，OPPO's design is currently only a patent，It does not mean that OPPO will definitely mass-produce this model。
