In July 2017, LG submitted a patent application for flexible folding screen equipment to the World Intellectual Property Organization, which was passed in January 2018.

The patent shows that the screen of LG's folding screen device is located at the inner side of the device. When the device folds the screen, its outer cover will be pushed away and the auxiliary screen on the right side of the outer layer will be displayed. The auxiliary screen can display time content. At the same time, this device is equipped with a camera at the diagonal position. The overall shape is very strange, which is worthy of LG's hand.

Since Samsung publicly displayed the flexible OLED screen at the exhibition, we have heard many rumors about flexible screen phones, and Samsung and LG have also applied for many related patents. However, in fact, the first mass production flexible screen device (mobile phone) should be from Samsung. It is reported that Samsung will release the Galaxy X series of flexible folding screen mobile phones later this year.
