Embodiment 1

[0042] Such as Figure 2-4 As shown, the adhesive material provided by this embodiment includes an adhesive base layer 1 for being arranged between two modules. The adhesive base layer 1 is divided into a bonding area 12 and a bending load buffer area 11. For bonding two modules, the bending load buffer area 11 is located between the two modules, and the bending stress of the bending load buffer area 11 is smaller than the bending stress of the bonding area 12 . When bending occurs, the bending stress of the bending load buffer zone 11 is smaller than the bending stress of the bonding area 12 . Then when this adhesive material is bonded to two modules, and when bending occurs, for the entire flexible module, the bending stress of the bending load buffer area 11 and its corresponding module parts is smaller than that of the bonding area 12 and its corresponding parts. The corresponding bending stress of the module part. Therefore, for adhesive materials or flexible modules th...

Embodiment 2

[0053] Such as Figure 5 As shown, this embodiment also provides a flexible module, which includes a lower first module part 3 and an upper second module part 4, which also includes the adhesive material in the first embodiment above. The first module part 3 and the second module part 4 are bonded to each other by glue.

[0054] Among them, the first module part 3 includes a graphite sheet 33, a display screen 32, and a circular polarizer 31 arranged sequentially from bottom to top; the second module part 4 includes a touch part 43 and an adhesive layer arranged sequentially from bottom to top. 42 . The protective layer 41 ; wherein, the adhesive material is disposed between the circular polarizer 31 and the touch portion 43 . The adhesive material includes an adhesive base layer 1 arranged between two modules. The adhesive base layer 1 is divided into a bonding area 12 and a bending load buffer area 11. The bending load buffer area 11 is located between the two modules. The...

Embodiment 3

[0057] This embodiment also provides a display device, which includes the flexible module in the second embodiment. The display device uses the flexible module in the second embodiment above.

[0058] The display device includes a display substrate, and the display substrate includes an opaque area; the orthographic projection of the bending load buffer zone 11 on the display substrate on the adhesive base layer is located in the opaque area, that is to say, the adhesive material base layer 1 The bending load buffer zone 11 overlaps with the opaque area of ​​the display substrate in correspondence with each other, and has the effect of not affecting the display effect. At the same time, the display device also has the same beneficial effects as the flexible module in the second embodiment. The display device can be any electrical device that can be applied with a flexible module, such as a mobile phone, a tablet, and a computer.

Abstract

The invention relates to the technical field of display, in particular to an adhesive material, a flexible module, display equipment and a manufacturing method of the flexible module. The adhesive material comprises an adhesive material base layer arranged between two modules, the adhesive material base layer comprises a bonding area and a bending load buffering area, the bonding area is used for bonding the two modules, the bending load buffering area is located between the two modules, and the bending stress of the bending load buffering area is smaller than that of the bonding area; after the two modules are bonded through the adhesive material, the bending stress of the bending load buffering area and the module portion corresponding to the bending load buffering area is smaller than that of the bonding area and the module portion corresponding to the bonding area for the whole flexible module. Therefore, the bending stress of the module entirety is decreased, and the adhesive material is beneficial for application and popularization.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an adhesive material, a flexible module, a display device and a method for manufacturing the flexible module. Background technique [0002] At present, the flexible display module has a multi-layer film structure, and the overall module thickness is usually 400-600um. Each functional film layer needs to be bonded with optical adhesive, such as figure 1 As shown, the first module part 3 and the second module part 4 are completely bonded together through the adhesive base layer 1, so that the overall module becomes thicker. The bending strength of the overall module is relatively large, which cannot meet the requirements of flexible product structure and mechanical mechanism design. In addition, excessive bending stress will also lead to peeling off of the optical adhesive and damage to the function of each functional film layer. Contents of the invention [0003] (1) Technic...
