Abstract
The invention discloses a flexible cover plate, an organic display panel, a display device, and a manufacturing method, and problems exist in a flexible cover plate in the prior art that hardness is low, bending resistance is poor, and a bending region easily breaks when an ink layer has relatively good shielding performance are improved. The flexible cover plate has a bending region and a non-bending region. The flexible cover plate at least comprises a first flexible film layer, a hard coating covered on the first flexible film layer, and a second flexible film layer bonded on one surface ofthe first flexible film layer, opposite to the hard coating. The surface of the first flexible film layer, facing the second flexible film layer, is provided with a first shielding layer on a frame region. The first shielding layer is provided with a groove structure on the region corresponding to the bending region. The surface of the second flexible film layer, opposite to or facing the first flexible film layer, is provided with a second shielding layer on a frame region and on a region corresponding to the bending region.
Description
technical field [0001] The invention relates to the technical field of semiconductors, in particular to a flexible cover plate, an organic display panel, a display device and a manufacturing method. Background technique [0002] At present, the market share of flexible display products is increasing, and flexible display products rely on organic light-emitting display devices, which can realize curling and folding. Folding products require a folding radius of 3mm or even 1mm. For such bending conditions, not only the light-emitting device itself has high bending resistance requirements, but also module materials such as polarizers and Optically Clear Adhesive (OCA) , cover plates, etc. have high requirements for bending resistance. [0003] For the cover plate of flexible display, the structure of flexible film layer plus hard coating is mainly used in the industry at present, and ink printing needs to be performed on the edge of the cover plate. However, the flexible cove...
