Abstract: A flexible screen display device includes: a hollow housing having an opening; a receiving shaft fixed inside the housing; a first guiding shaft fixed inside the housing; a second guiding shaft fixed inside the housing; a flexible screen, one end of which is connected to the receiving shaft, and the other end of which sticks out of the opening via the first guiding shaft and the second guiding shaft to deploy or receive the flexible screen. The first guiding shaft is close to the receiving shaft with respect to the second guiding shaft, and the flexible screen forms a one-time guided bending section via the first guiding shaft and the second guiding shaft.

Abstract: The flexible display module can be curled, and may comprise: a flexible display panel having a display side and a rear side which are provided opposite to each other in a thickness direction of the flexible display panel; a first functional film layer, formed on a display side of the flexible display panel; and a second functional film layer, formed on the rear side of the flexible display panel. The ratio of the thickness of the second functional film layer to the thickness of the first functional film layer is 0.5 to 1.5, and the ratio of the elasticity modulus of the second functional film layer to the elasticity modulus of the first functional film layer is 0.5 to 1.5. The flexible display module is not prone to peeling, losing efficacy and the like.
