Popular Chinese smartphone brand Oppo is bringing something "new" to the table once again. As smartphone giants Samsung and Huawei proudly flexes their foldable phones on the market today. Oppo is leveling-up the game by taking the advantages of OLED's flexibility even further and release the first rollable smartphone - at least as a concept phone for now. Meet Oppo's X 2021, a phone that can expand its size diagonally from a 6.7 inches up to 7.4 inches by rolling its screen. Check out a live demo of it from Geekbuying Studio YouTube channel.
Rollable OLED screens aren't new actually as LG already release of its kind on there television line-ups but this is the first time for a company to create a rollable smartphone. Oppo is known for making bold steps in terms of smartphone design. Oppo is wildly known for its Oppo Find X smartphone back in 2018 when they release it on the market. Oppo Find X features an all screen design, no notch nor punch-hole for front-facing camera and no fixed back camera. Instead, both front and back camera were hidden and can only reveal by sliding it.
