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

Embodiment Construction

[0037] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0038] Such as figure 1 , 2 As shown in , 3, 4, and 5, an OLED folding or windable screen and its manufacturing process, when the screen is folded, it includes an OLED display layer, a soft glue layer, a printing layer, a base material, and a hardened layer;

[0039] Folding screen, the inward folding structure of the screen is: a hardened layer is provided above the substrate, a printing layer is provided below the substrate, a soft rubber layer is provided below the printing layer, and an OLED is provided below the soft rubber layer. display layer;

[0040] Folding screen, the outer folding structure of the screen is as follows: a hardened layer is provided under the base material, a printing layer is provided above the base material, a soft rubber layer is provided above the printing layer, and an OLED is provided above the soft rubber layer. d...

Abstract

The invention provides an OLED folding or winding type screen and a manufacturing process thereof, and the OLED folding or winding type screen comprises an OLED display screen layer, a flexible glue layer, a printing layer, a base material and a hardening layer when the screen is folded. When the screen is outside, a hardening layer is arranged below the base material, a printing layer is arrangedabove the base material, a flexible glue layer is arranged above the printing layer, and an OLED display screen layer is arranged above the flexible glue layer; wherein the light transmittance of thebase material should be greater than 88%; the purpose of hardening the surface of the base material is to improve the scratch resistance and fingerprint resistance of the base material; the purpose of printing treatment on the surface of the base material is to improve the flexibility and adherence between the base material and the flexible glue; the beneficial effects of the invention are that the flexible glue design enables the substrate not to be stretched and contracted when the substrate is bent, and guarantees that the protection film, the TP and the OLED cannot be layered and folded;and edge dust adhesion in the deformation process of the flexible glue layer is avoided by reducing the size of the flexible glue.

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 ...
