Embodiment Construction
[0050]Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.
[0051] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of an icon to another component, these terms are used in this specification only for convenience, for example, according to the description in the accompanying drawings directions for the example described above. It will be appreciated that if the illustrated device is turned over so ...

Abstract
The present disclosure relates to the field of display technology, in particular, to an adhesive structure, a manufacturing method thereof, and a display device. The adhesive structure at least includes an intermediate adhesive layer and a first adhesive layer and a second adhesive layer located on both sides of the intermediate adhesive layer, and the viscosity of the first adhesive layer and the second adhesive layer is greater than the viscosity of the intermediate adhesive layer, and the elastic modulus of the intermediate adhesive layer is smaller than the elastic modulus of the first adhesive layer and the second adhesive layer. The bonding structure of the embodiments of the present disclosure has high viscosity, low elastic modulus and high creep recovery performance, so as to ensure that the film layers in the display device are peeled off during the folding process.
Description
technical field [0001] The present disclosure relates to the field of display technology, in particular, to an adhesive structure, a manufacturing method thereof, and a display device. Background technique [0002] At present, OLED (Organic Light Emitting Display, Organic Light Emitting Diode) display panels have been widely used in various electronic products; with the diversification of flexible products, folding display products have emerged; but with the development of new forms of folding products , For example: water drop shape, baseball shape, U shape + 3D bending (three-dimensional bending) and other new forms, the problem of peeling (peeling) between film layers is prominent. [0003] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the ar...
