Embodiment 1

[0028] figure 2 A schematic structural diagram of a foldable display module provided by an embodiment of the present disclosure, as shown in figure 2 As shown, the folding display module includes a plurality of functional layers 10; at least part of the adjacent functional layers 10 are connected by an adhesive layer 101; at least part of the adhesive layer 101 includes a multi-layered sub-adhesive layer 1011 .

[0029] In the folding display module provided by the embodiment of the present disclosure, at least part of the adjacent functional layers 10 are connected by the adhesive layer 101 composed of multiple sub-adhesive layers 1011 arranged in layers, so that during the folding process, The original misalignment between two adjacent film layers can be decomposed by the multi-layer sub-adhesive layer 1011, so that the misalignment between the sub-adhesive layer 1011 and the adjacent functional layer 10 is reduced, so it can be Preventing the peeling phenomenon between ...

Abstract

The invention provides a folding display module and a display device, belongs to the technical field of display, and can solve the technical problem that an existing folding display module is prone tolayering in the folding process. The folding display module provided by the invention comprises a plurality of functional layers, at least part of the adjacent functional layers are connected througha bonding layer; at least part of the bonding layer comprises a plurality of sub-bonding layers which are arranged in a laminated mode.

Description

technical field [0001] The disclosure belongs to the field of display technology, and in particular relates to a folding display module and a display device. Background technique [0002] With the development of flexible organic light-emitting diode (Organic Light-Emitting Diode, OLED) display technology, foldable OLED products gradually begin to enter the market. [0003] At present, adjacent parts in folded OLED products are laminated with a single-layer adhesive layer, and single-layer adhesive layers with different thicknesses can be selected according to different parts. After a folded OLED product is used for a long time and folded many times, the adhesive layer is easily peeled off from the surface of the attached part, resulting in delamination of the folded OLED product. Aiming at the problem of delamination in folded OLED products, it is currently mainly relying on manufacturers to adjust parameters such as viscosity and cohesion of the adhesive layer to improve. ...
