Manufacturing method of flexible display device

Abstract

The invention belongs to the field of displayers, and discloses a manufacturing method of a flexible display device. The manufacturing method of the flexible display device comprises the following steps that a rigid substrate is coated with an isolation layer and a frame sealing glue layer, the rigid substrate is coated with organic materials to form a flexible substrate, a flexible display device is manufactured on the flexible substrate, ultraviolet exposure is conducted, and residues are removed. According to the manufacturing method of the flexible display device, radical group matter is added to enable the isolation layer to have anti-adhesion performance, the periphery of the isolation layer is coated with the modified frame sealing glue layer, the frame sealing glue layer has good anti-adhesion performance, the ultraviolet exposure is conducted, the frame sealing glue layer is resolved, and therefore the flexible substrate is naturally separated from the rigid substrate. According to the manufacturing method of the flexible display device, separating performance is good, the residues are few, technological process is simple, and the manufactured flexible display device is good in flexibility, and good in display quality.

Description

technical field [0001] The invention belongs to the field of displays, in particular to a method for manufacturing a flexible display device Background technique [0002] In recent years, flexible display technology has developed very rapidly, and it is a research hotspot in universities and research institutions at home and abroad. The continuous progress of various advanced manufacturing processes and technologies has not only increased the screen size of flexible displays, but also continuously improved the display quality. Flexible displays, also known as rollable displays, are display devices that can be bent and deformed arbitrarily made of visible panels made of flexible materials, including electronic paper, flexible liquid crystal displays, and flexible organic electroluminescent display devices. Compared with ordinary rigid displays, flexible displays have many advantages: light weight, small size, thin, easy to carry; high and low temperature resistance, impact r...

Problems solved by technology

Although this method is simpler than the prior art process and does not require high-energy laser beam scanning, in the above-mentioned patent documents, although ultraviolet radiation can cause the release layer to release gas, so that the release layer and the transparent hard substrate ( Made of inorganic materials such as glass) are easy to separate, but we know that organic materials and inorganic materials are easy to separate, but when organic materials and organic materials are adhered together, it is not easy to separate. Since the material of the release layer is organic material, The material of the flexible substrate is also an organic material, and the area of ​​the release layer is relatively large. Therefore, in the technical solution of the above-mentioned patent, although the release layer can be peeled off from the transparent hard substrate, the final release layer will still be separated from the transparent hard substrate. The flexible substrate is bonded together as part of its structure, and the resulting problem is that the flexibility of the flexible substrate is deteriorated, resulting in low flexibility of the flexible display device; and the transparency is reduced, which affects the light extraction efficiency, and finally Deteriorating the display quality of flexible display devices
