Abstract: A display assembly includes a screen assembly, a rigid cover plate, and a supporting member. The screen assembly includes a flexible display and a flexible cover plate which covers the flexible display. An edge of the flexible display has a first extending part and an arc-shaped outer surface of the first extending part. An edge of the flexible cover plate has a second extending part, an inner surface of the second extending part is an arc-shaped surface, the arc-shaped surface of the outer surface of the first extending part matches the arc-shaped surface of the inner surface of the second extending part, and the second extending part covers the first extending part. An edge of the supporting member has a first side surface that is an arc-shaped surface, the arc-shaped surface of the first side surface matches an arc-shaped surface of an inner surface of the first extending part.

Abstract: A supporting structure that supports a flexible screen includes planar supporting portions and a bending supporting portion. The bending supporting portion includes a bending skeleton and a flexible supporting bar coupled to the bending skeleton, and the flexible supporting bar is in direct contact with the flexible screen. The flexible supporting bar includes a supporting portion and a plurality of connecting portions that are distributed at intervals and fastened to the supporting portion. The supporting portion is coupled to the flexible screen. The connecting portions are located on a side of the supporting portion away from the flexible screen, and an end of each of the plurality of connecting portions away from the supporting portion is coupled to the bending skeleton.

Abstract: A protective film includes an adhesive layer and a base film layer that are stacked. The adhesive layer is configured to adhere to a foldable display. The base film layer includes one or more layers of high-modulus base film and one or more layers of low-modulus base film. An elastic modulus of the high-modulus base film is greater than an elastic modulus of the low-modulus base film. The high-modulus base film and the low-modulus base film are alternately stacked. A surface layer in the base film layer and non-adjacent to the adhesive layer is the high-modulus base film. The protective film is configured to be firmly attached to the foldable display, resists rebounding and warping when the display is bent, and protects the foldable display.
