Abstract
The invention provides a cover plate assembly and a manufacturing method thereof. The cover plate assembly comprises a cover plate base material; the hardened coating is located on the cover plate base material and comprises a first film layer and a second film layer located on the first film layer, and the difference value between the refractive index of the first film layer and the refractive index of the cover plate base material is within a preset range; wherein the second film layer is provided with a plurality of openings, the sizes of the openings in the first direction in the direction away from the cover plate base material are gradually increased, so that the refractive index of the second film layer in the direction away from the cover plate base material is gradually reduced, and the first direction is parallel to the main plane of the cover plate base material. By forming the second film layer with the refractive index gradually decreasing in the direction away from the cover plate base material, the impression of creases can be relieved visually, so that the problem of the creases of the flexible device is solved, and the appearance effect of the flexible device is improved.
Description
【Technical field】 [0001] The invention relates to the field of display technology, in particular to a cover assembly and a manufacturing method thereof. 【Background technique】 [0002] With the vigorous development of science and technology, flexible displays have gradually achieved mass production and commercialization. Organic electroluminescent (Organic Light-Emitting Diode, OLED) flexible devices are considered to be a new generation of display technology, and repeatedly foldable modules can be prepared through OLED flexible devices. In order to ensure the bending characteristics, it is necessary to replace the commonly used cover plate with a foldable material from glass. At present, materials such as transparent polyimide (CPI) or polyethylene terephthalate (PET) are often used as covers. plate material to realize the bending of the display device. [0003] However, in actual use, after repeated bending, the bending part of the flexible device is easy to form obvious...
