Abstract
A stretchable display device includes a first stretchable display panel and a second stretchable display panel overlapping the first stretchable display panel. The first stretchable display panel includes a first stretchable substrate having a first length and a plurality of first pixels spaced apart from one another on the first stretchable substrate. The second stretchable panel includes a second stretchable substrate and a plurality of second pixels spaced apart from one another on the second stretchable substrate. The first stretchable substrate is stretchable in a first direction to have a second length. When the first stretchable substrate is stretched to have the second length, the second pixels are each positioned between the plurality of first pixels when viewed from a plan view.
Claims20
A stretchable display device comprising:
- a first stretchable display panel;
- and
- a second stretchable display panel overlapping the first stretchable display panel,
- wherein the first stretchable display panel includes a first stretchable substrate having a first length and a plurality of first pixels spaced apart from one another on the first stretchable substrate, and
- the second stretchable panel includes a second stretchable substrate and a plurality of second pixels spaced apart from one another on the second stretchable substrate,
- wherein the first stretchable substrate is stretchable in a first direction to have a second length, and
- when the first stretchable substrate is stretched to have the second length, the second pixels are each positioned between the plurality of first pixels when viewed from a plan view.
A display device, comprising:
- a first stretchable display panel comprising a first stretchable substrate having a first length in a non-stretched state, wherein the first stretchable substrate is stretchable in a first direction to at least a second length greater than the first length;
- a second stretchable display panel comprising a second stretchable substrate having the second length, wherein the second stretchable substrate is stretchable in the first direction,
- wherein end portions of the first stretchable substrate are each coupled to corresponding end portions of the second stretchable substrate, and wherein the second stretchable substrate includes at least one curved portion when the first stretchable substrate is in a non-stretched state;
- a plurality of first pixels arranged on the first stretchable substrate;
- and
- a plurality of second pixels arranged on the second stretchable substrate,
- wherein when the first stretchable substrate is stretched in the first direction, the second stretchable substrate flattens until it reaches a substantially flat state, and
- wherein when the first stretchable substrate is stretched to the second length, each of the second pixels is spaced apart from each of the first pixels when viewed from a plan view.
