Flexible display panel and flexible display device

Abstract

The invention discloses a flexible display panel and a flexible display device. The flexible display panel comprises a bending area and a non-bending area, the bending area comprises a bending shaft,and the bending shaft extends in the first direction; the flexible display panel comprises a plurality of functional film layers, and the every two or more adjacent functional film layers are connected through an adhesive layer; two or more retaining walls are arranged between each adhesive layer and the corresponding adjacent functional film layer and extend in the first direction; each retainingwall comprises a first retaining wall and a second retaining wall; the bending area is arranged to be adjacent to the retaining walls, and in the second direction, the bending area is located betweenthe first retaining walls and the second retaining walls; and the second direction and the first direction are crossed. According to the technical scheme, the retaining walls can achieve the limitingeffect on the adhesive layers in the bending area, the situation that the adhesive layers in the bending area move in the direction of the non-bending area in the bending process is avoided, the thinning phenomenon of the adhesive layers in the bending area is avoided, deformation is easy to restore, and thus the phenomenon of folds or adhesive failure formed in the bending area is avoided.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a flexible display panel and a flexible display device. Background technique [0002] Flexible display panels have the advantages of being deformable and bendable, and are favored by users, especially flexible organic light-emitting display panels, which not only have the above advantages, but also self-illuminate, and have high luminous efficiency, short response time, and high clarity and contrast. , gradually becoming the first choice for flexible display panels. [0003] The flexible organic light emitting display panel in the prior art includes multiple functional film layers and multiple adhesive layers, and the adhesive layer is used to connect two adjacent functional film layers. In the actual use process, the organic light emitting flexible display panel is repeatedly bent, The strain of the adhesive layer belonging to the viscoelastic body la...

[0003] The flexible organic light emitting display panel in the prior art includes multiple functional film layers and multiple adhesive layers, and the adhesive layer is used to connect two adjacent functional film layers. In the actual use process, the organic light emitting flexible display panel is repeatedly bent, The strain of the adhesive layer belonging to the viscoelastic body lags behind the stress, and there is energy loss, which makes the adhesive layer unable to quickly and completely recover from deformation, and then forms wrinkles. At the same time, the thickness of the adhesive layer in the bending area is thinned, thereby forming a peeling force in the stacking direction of multiple functional film layers, causing the adhesive layer to separate from the adjacent functional film layers, and debonding occurs
