Abstract
Provided is an adhesive provided by patterning a metal plate with a predetermined elastic modulus, wherein the adhesive is compressively deformed in response to an operation of an adherend to be folded, so that the adhesive can easily return to an original state thereof through formation of a plurality of inner neutral planes upon deformation.
Claims15
An adhesive, comprising:
- a metal plate having a first surface and a second surface opposite to the first surface, and a plurality of hollows regularly spaced apart from each other, the metal plate having an elastic modulus of between 10 GPa and 100 GPa, inclusive;
- and
- an adhesive layer provided on at least one of the first surface and the second surface.
A flexible display, comprising:
- a display panel including a thin film transistor array, an organic light emitting diode array, an encapsulation layer for sealing the thin film transistor array and the organic light emitting diode array;
- a back plate facing the display panel, the back plate including a folding region and a non-folding region;
- and
- an adhesive including
- a metal plate having a first surface and a second surface opposite to the first surface, and a plurality of hollows regularly spaced apart from each other, and having an elastic modulus between 10 GPa and 100 GPa, inclusive, and
- an adhesive layer provided on at least one of the first surface and the second surface.
