With the advent of the full screen era, light, thin and foldable flexible screens are becoming popular in the market, but folding screen mobile phones have a "shortcoming" that is, the folding screen cannot be docked without a trace. As shown in fig. 1 and 2, after the folding screen is unfolded, the middle part of the folding screen has a significant crease, so that no good way is provided so far as how to eliminate the crease. The presence of folds directly affects the user's experience.
As shown in fig. 3 and 4, in the prior art, since the flexible screen is relatively thin and is easily deformed, in order to ensure the flatness of the screen 1, the support metal plate 2 is usually added behind the screen 1 to assist, but considering the bending property of the folded screen, the support metal plate 2 behind the screen 1 is divided into two pieces in the bending area and a certain gap exists between the two pieces.
Therefore, the screen 1 of the prior art is not effectively supported at the portion supporting the gap of the metal plate 2, and is liable to be creased, as shown in fig. 5, particularly, the wavy crease is left in a clear under a black background.
To this end, those skilled in the art have been directed to developing a support and protection device that can effectively support the bending portion of a flexible screen.
