In one aspect of the present application, a flexible display screen is provided. According to an embodiment of the present application, referring to fig. 1 and 2 (fig. 2 isbase:Sub>A cross-sectional view alongbase:Sub>A-base:Sub>A' in fig. 1), the flexible display screen includes: the flexible display screen module 10 is characterized in that the flexible display screen module 10 is provided with a bending area 11 and non-bending areas 12 positioned at two sides of the bending area 11; the flexible display screen module 10 comprises an elastic film 20, an elastic region 21 and a flexible display screen, wherein the elastic film 20 is arranged on the back of the flexible display screen module 10; the adhesive layer 30, the adhesive layer 30 is arranged between the flexible display screen module 10 and the elastic film 20; the whole cooling fin 40, the cooling fin 40 laminating sets up on the surface that the flexible display screen module 10 is kept away from to elastic film 20, and the orthographic projection of cooling fin 40 on flexible display screen module 10 covers at least partly of both sides non-bending zone 12 and at least partly of bending zone 11, wherein, there is not the overlap region elastic zone 21 and the orthographic projection of glue film 30 on elastic film 20, and does not have the overlap region with the orthographic projection of cooling fin 40 on elastic film 20. Therefore, as the radiating fins are integral radiating fins, the heat generated by the flexible display screen module 10 can be uniformly dispersed to the whole radiating fins, the bad phenomenon of over-high local temperature is avoided, and the radiating effect of the flexible display screen is further improved; moreover, when the flexible display screen is bent, the elastic membrane at the elastic area is stretched to compensate the length difference between the radiating fins and the flexible display screen module caused by different bending radiuses, so that the radiating fins are prevented from being broken, and the flexible display screen module is prevented from being cracked by extrusion.
In the embodiment of the present application, referring to fig. 3, when the flexible display panel is bent, the elastic film 20 and the heat sink 40 corresponding to the bending region 11 of the flexible display panel module 10 are bent together, the elastic film 20 at the elastic region 21 is stretched in the bending process, the elastic films at other regions are not stretched, the heat sink 40 attached to the elastic film 20 is not stretched, but the heat sink 40 contracts toward the bending region along with the stretching of the elastic film 20 at the elastic region 21 (the contraction does not mean that the size of the heat sink contracts, but means that the edge of the heat sink 40 approaches toward the bending region along with the stretching of the elastic film at the elastic region), that is, the size of the heat sink 40 does not change in the bending process, the elastic film 20 at the elastic region 21 is stretched, and a length difference between the heat sink 40 and the flexible display panel module 10 due to different bending radii is compensated, so that the heat sink is prevented from being pulled apart, and the flexible display panel module is prevented from being crushed. The stretched length Δ L = L' -L = (R-R)/2 of the elastic film 20 in the elastic region 21, where R is a bending radius of the surface of the flexible display panel module away from the elastic film when the flexible display panel is bent, and R is a bending radius of the surface of the flexible display panel module away from the elastic film when the flexible display panel is bent.
