Abstract
A shock absorbing module includes a shock absorbing layer at which the shock absorbing module is attachable to a display panel, the shock absorbing layer including a cushion layer including an adhesive polymer resin, and a hollow particle which is in the adhesive polymer resin, and an embossed adhesive layer with which the shock absorbing layer is attachable to the display panel, and a base layer. The shock absorbing module attached to the display panel disposes the shock absorbing layer between the display panel and the base layer.
Claims20
A shock absorbing module, comprising:
- a shock absorbing layer at which the shock absorbing module is attached to a surface of a display panel which is opposite to a display surface of the display panel, the shock absorbing layer comprising:
- a self-adhesive cushion layer comprising an adhesive polymer resin, and a hollow particle which is in the adhesive polymer resin,
- the self-adhesive cushion layer comprising the hollow particle which is in the adhesive polymer resin defining extended portions thereof spaced apart from each other, and
- the extended portions which are defined by the self-adhesive cushion layer defining an embossed adhesive layer of the shock absorbing layer which is attached to the surface of the display panel, and
- a base layer facing the shock absorbing layer.
A shock absorbing layer, comprising:
- a self-adhesive cushion layer which is attached to a surface of a display panel which is opposite to a display surface of the display panel, the self-adhesive cushion layer comprising:
- an adhesive polymer resin;
- a hollow particle in the adhesive polymer resin, the hollow particle comprising a polymerized acrylic monomer or a polymerized vinyl chloride monomer;
- and
- a carbon black nanoparticle in the adhesive polymer resin;
- the self-adhesive cushion layer comprising the hollow particle and the carbon black nanoparticle which are in the adhesive polymer resin defining extended portions thereof spaced apart from each other, and
- the extended portions which are defined by the self-adhesive cushion layer defining an embossed adhesive layer attached to the surface of the display panel.
A display device, comprising:
- a display panel;
- and
- a shock absorbing layer which is attached to a surface of the display panel which is opposite to a display surface of the display panel,
- wherein
- the shock absorbing layer comprises:
- a self-adhesive cushion layer comprising:
- an acrylic resin, and
- a hollow particle which is in the acrylic resin, has a mean diameter from about 10 μm to about 80 μm, and comprises a polymerized acrylic monomer or a polymerized vinyl chloride monomer;
- the self-adhesive cushion layer comprising the hollow particle defining extended portions spaced apart from each other, and
- the extended portions which are defined by the self-adhesive cushion layer defining an embossed adhesive layer of the shock absorbing layer,
- the embossed adhesive layer being attached to the surface of the display panel.
