Embodiment Construction

[0023] As mentioned in the background section, the flexible display device in the prior art has the problem of failure of the screen body after being bent or folded many times during long-term use.

[0024] The inventors have found that the reason for the above-mentioned technical problems is that the flexible display device is usually pasted together with a multi-layer structure by an adhesive, and the adhesive is in a semi-cured state. The characteristic of the flexible display device is that it is often bent or folded. During the alternate transformation between the bent state and the flat state, the bending stress is generated inside the adhesive material, and the cohesive failure of the adhesive material occurs, thereby causing degumming; at the same time, the adhesive material and other layers Between the contact interfaces, due to the existence of bending stress, the adhesion between the adhesive material and the contact interfaces of other layers is poor, and there is a...

Abstract

The invention discloses a flexible display module, a manufacturing method thereof and a flexible display device. In the flexible display module, magnetic material layers are arranged on two sides of apart, located in a non-display area, of an optical adhesive layer, and the magnetic pole directions of the magnetic material layers are the same. According to the principle of opposite attraction, the magnetic material layers attract the part, located in the non-display area, of the optical adhesive layer, so that the binding force of the edge part of the optical adhesive layer is increased, andthe situation that an semi-cured optical adhesive layer is degummed at the edge part, and consequently the flexible display module fails is avoided. Meanwhile, the magnetic material layers are arranged in the non-display area, so that the influence of the arrangement of the magnetic material layers on the display of the flexible display module is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display module, a manufacturing method thereof, and a flexible display device. Background technique [0002] With the rapid development of display devices, large-screen smart mobile terminals have become a trend. The flexible display device has become the main means to increase the area of ​​the display screen because it can be bent and folded. [0003] A flexible display device usually uses glue to encapsulate multiple layers of flexible and bendable materials, so that each level of the flexible display device is packaged as a whole. [0004] However, the flexible display device in the prior art has the problem of failure of the screen body after being bent or folded many times during long-term use. Contents of the invention [0005] In view of this, the present invention provides a flexible display module, a manufacturing method thereof, and a flexible display d...
