Problems solved by technology

Since there are uneven areas such as grooves in the hinge structure, there is a gap between the groove of the hinge structure and the adhesive layer, so that in the reciprocating bending behavior, the extrusion deformation of the adhesive layer is very easy to occur, and further plugged in the hinge. Among them, the ability to restore the original shape is lost, which will cause the adhesive layer to have energy loss / viscosity drop / fracture failure, etc., and the failure of the adhesive layer in the bending area will cause the screen in the bending area to arch and cannot be pulled back , it cannot achieve a good external force leveling effect on the arched deformation of the entire display screen

no. 2 approach

[0048] The second embodiment: as Image 6 with Figure 7 As shown, in this embodiment, the hinge structure includes a plurality of protruding parts and a plurality of concave parts arranged in a staggered manner, and the elastic connection structure includes:

[0049] A first adhesive layer disposed between the raised portion and the flexible display panel, the thickness of the first adhesive layer is the same as that of the sealant;

[0050] A second adhesive layer disposed on the flexible display panel at a position corresponding to the inner recess, and the thickness of the second adhesive layer is the same as that of the sealant;

[0051] The first elastic filling part 4 filled in the inner concave part.

[0052] With the above technical solution, the setting of the first adhesive layer and the second adhesive layer ensures the adhesive force of the flexible display panel, and pre-fills the vacant position of the hinge groove (that is, fills the first adhesive layer in t...

no. 3 approach

[0061] The third embodiment: as Figure 8-Figure 12 As shown, the hinge structure includes a plurality of protruding parts and a plurality of concave parts arranged in a staggered manner, and the elastic connection structure includes:

[0062] A first adhesive layer disposed between the raised portion and the flexible display panel, the thickness of the first adhesive layer is the same as that of the sealant;

[0063] A second adhesive layer disposed on the flexible display panel at a position corresponding to the inner recess, and the thickness of the second adhesive layer is the same as that of the sealant;

[0064] The plane connecting layer 5 arranged on the side of the sealing glue, the first glue layer, and the second glue layer facing away from the flexible display panel, and the plane connecting layer 5 includes Extending and filling the second elastic filling part 6 of the inner concave part.

[0065] In this implementation manner, the second adhesive layer is dispo...

Abstract

The present invention relates to a display device, comprising a main structure and a flexible display panel arranged on the main structure, the main structure includes at least two non-bending regions and a bending region located between two adjacent non-bending regions , a hinge structure is provided on the bending area, a sealant is provided between the flexible display panel and the non-bending area, and a sealant is provided between the main structure and the flexible display panel to prevent the flexible The display panel corresponds to an elastic connection structure in which the bendable region of the hinge structure is transformed into a flat state and is difficult to recover from deformation. Through the arrangement of the elastic connection structure, a better connection force can be provided between the hinge structure and the flexible display panel, so that when the flexible display panel is converted from a bent state to a flat state, the flexible display panel corresponds to the hinge. The bendable area of ​​the structure can be better flattened to achieve a better planar effect.

Description

technical field [0001] The invention relates to the technical field of display product manufacturing, in particular to a display device. Background technique [0002] Organic Light Emitting Display (OLED) has gradually become the first choice for screens. It has many advantages such as self-illumination, high luminous efficiency, short response time, high definition and contrast, and can also ensure that the screen has certain flexibility and reliability. adaptability. With the development of flexible display screens, people's expectations for foldable display products are getting higher and higher. [0003] For the folding display, because the bending area performs the unfolding and bending actions of folding, it is necessary to design hinges and other movable mechanisms in the bending area on the whole machine; activity action. Then the screen needs to be bonded with a strong and soft adhesive glue, so as to ensure that the whole machine is flattened after the screen is...
