The present embodiment provides a flexible display panel and a display device, and the flexible display panel 10 is described in detail below.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a flexible display panel according to an embodiment of the present disclosure. Wherein, flexible display panel 10 includes flexible panel 11, encapsulation glue film 12 and apron 13, and flexible panel 11 has relative first face 11a and the second face 11b that sets up, encapsulation glue film 12 covers first face 11a and second face 11b, and the parcel one of them lateral part of panel, apron 13 covers the surface of encapsulation glue film 12, and with the area of encapsulation glue film 12 correspond in order to realize flexible panel 11 with apron 13 is connected.
The first surface 11a is an upper surface of the flexible panel 11, and the second surface 11b is a lower surface of the flexible panel 11. Of course, the first surface 11a may be a lower surface of the flexible panel 11, and the second surface 11b may be an upper surface of the flexible panel 11. In addition, the flexible panel 11 is a panel having bending properties.
Wherein, the packaging adhesive layer 12 and the cover plate 13 are integrally formed.
Referring to fig. 2, fig. 2 is a schematic view illustrating another structure of a flexible display panel according to an embodiment of the present disclosure. The flexible panel 11 has an extension portion 111, the extension portion 111 extends from an edge of the cover plate 13 toward an outside, and the extension portion 111 is connected to the flexible circuit board 14. Because the flexible panel 11 has the extension portion 111, when the flexible display panel 10 is bent, even if the cover 13 and the flexible panel 11 are deviated due to bending, the cover 13 and the flexible panel 11 can be ensured to be in full contact, and the cover 13 and the flexible panel 11 cannot be separated by dislocation after bending, and meanwhile, the extension portion 111 can be conveniently connected with the flexible circuit board 14.
Wherein the flexible circuit board 14 is connected to the first surface 11a of the extension portion 111. Of course, the flexible circuit board 14 may be connected to the second surface 11b of the extension portion 111.
