Problems solved by technology

[0002] In the existing flexible display panels, such as OLED panels, three-layer thin film packaging technology is usually used, the stress acting on the inorganic layer and the organic layer is different, the stress cannot be released when bending, and the regional stress is concentrated
Therefore, during the bending process, the inorganic layer and the organic layer in the thin film encapsulation layer are prone to film layer separation or the inorganic layer is easy to break, resulting in encapsulation failure, and the intrusion of water and oxygen in the air damages the flexible display panel.
At the same time, when the light emitted by the light-emitting layer group of the flexible display panel exits, due to the mismatch of the refractive index between the film layers, a certain proportion of the light cannot be emitted and remains inside the flexible display panel, making the external quantum efficiency (External Quantum Efficiency) of the flexible display panel Quatum Efficiency) is not high

Abstract

The application discloses a flexible display panel and a display device. The flexible display panel comprises a luminous layer set, a scattering layer arranged on the surface of the luminous layer setand a thin-film packaging layer arranged on the surface of the scattering layer far away from the luminous layer set, wherein the scattering layer comprises an organic material main body and scattering particles doped to the organic material main body. Through the manner, the flexible display panel and the display device in the application can improve the flexibility of the thin-film packaging layer as well as improve the external quantum efficiency.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a flexible display panel. The present application also relates to a display device comprising such a flexible display panel. Background technique [0002] In existing flexible display panels, such as OLED panels, three-layer thin-film packaging technology is usually used, and the stress acting on the inorganic layer and the organic layer is different, and the stress cannot be released when it is bent, and the regional stress is concentrated. Therefore, during the bending process, separation between the inorganic layer and the organic layer in the thin-film packaging layer is easy to occur, or the inorganic layer is easy to break, resulting in packaging failure, and the intrusion of water and oxygen in the air damages the flexible display panel. At the same time, when the light emitted by the light-emitting layer group of the flexible display panel exits, due to the mi...
