Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the adhesive layer or film is stretched or shrunk due to the difference in thickness during folding, and the shrinkage causes the adhesive layer to be separated from the screen, and the displacement of the substrate will cause the adhesive layer to be deformed and exposed and cause dust and other sticking reasons. There are products that can no longer meet the demand, but provide an OLED folding or windable screen and its manufacturing process

Abstract

The invention provides an OLED folding or wrapping screen and a manufacturing process thereof. When the screen is folded, it includes an OLED display screen layer, a soft glue layer, a printing layer, a base material and a hardened layer; There is a hardened layer, a printing layer is arranged above the substrate, a soft adhesive layer is arranged above the printing layer, and an OLED display layer is arranged above the soft adhesive layer; the light transmittance of the substrate should be >88%; the surface of the substrate is hardened The purpose is to increase the scratch resistance and anti-fingerprint performance of the substrate; the purpose of the surface printing treatment of the substrate is to increase the flexibility and adhesion between the substrate and the soft glue; the beneficial effect of the present invention is: through the design of the soft glue, the The substrate does not stretch and shrink when it is bent, ensuring that there will be no delamination and crease between the protective film, TP and OLED; by reducing the size of the soft glue, the edges of the soft glue layer are prevented from sticking to dust during the deformation process.

Description

【Technical field】 [0001] The invention relates to a manufacturing process of an OLED folding screen, in particular to an OLED folding or windable screen and a manufacturing process thereof. 【Background technique】 [0002] With the rapid application of OLED flexible screens, more and more terminal brands are rapidly deploying rollable screen mobile phones. Samsung, Huawei, Royole, Apple, Xiaomi, etc. have released or plan to release flexible OLED rollable screens. Application, the patent of the present invention mainly aims at the following two problems; [0003] At present, the method of attaching the screen protective film of the rollable screen mobile phone to the market or announced will cause the adhesive layer or film to stretch or shrink due to the thickness difference when folding, so that the film at the folded bend will cause creases or creases due to stretching and shrinking. The adhesive layer is separated from the screen due to stretching and shrinkage, and the ...
