After OPPO X 2021, a scroll screen mobile phone, was released in November, OPPO released a "slide phone" on December 14 Three hinge folding screen "concept mobile phone. This is the first time that a mobile phone manufacturer has released a concept machine that is so advanced and difficult to implement.

This machine was jointly launched by OPPO and Japanese industrial design studio endo. The goal is to design a large screen device that is easy to hold, so that the latter can change the size of the phone according to the needs of different occasions.

The OPPO slide phone body is composed of three hinged 4-segment bodies, with a total screen length of 7 inches. By default, it is a fold over model, which is about the same size as the previous non intelligent machines. The back is a full black, grid by grid "bamboo" design with arc edges. The concept machine even has a 4-camera configuration. The combination of different spindles can make the phone display 8cm and 4cm long screens, even with a stylus.

The settings given by OPPO are:

• Sliding one grid, the screen length is 4cm, which can be used to display simple notifications, music players and other small interactive components;

• And then slide up, it will become an 8cm long screen. The location of the camera is just suitable for video calls or photos;

• Turn over the above summary completely, and the rear camera can be used to take selfies;
  

• When it is fully opened, it is a super long "hairtail screen", which can parallel three apps horizontally (in fact, it can parallel five or six apps, but the font will become very small).

There is a saying that this concept machine is a real concept machine and does not consider mass production and cost factors, such as battery capacity, shaft life, reliability, technical pressure of ultra small bending radius on flexible screen, etc. Of course, mass production is not the task of designing the concept machine itself.

Also released with this OPPO slide phone with an exaggerated folding screen is a Bluetooth wireless headset called "music link", which features a stack of accessories and can be stored away from the charging box.

The earphone has a unique shape (it may be uncomfortable to wear). If the two earphones are misplaced and buckled reversely, they can be looped into a circle. It can work with its own smart watch, smart speaker and charging box.
