Abstract
A stretchable display includes a stretchable substrate including a flat part and a plurality of protrusions protruding above the flat part, a plurality of fixed light emitting devices, each fixed light emitting device being attached to an upper surface of a corresponding protrusion of the plurality of protrusions, a plurality of moving light emitting devices, the moving light emitting devices being positioned among the plurality of protrusions, and a plurality of connection wirings connecting among the plurality of fixed light emitting devices and the plurality of moving light emitting devices.
Claims20
A stretchable display, comprising:
- a stretchable substrate including a flat part and a plurality of protrusions protruding above the flat part;
- a plurality of fixed light emitting devices, each fixed light emitting device being attached to an upper surface of a corresponding protrusion of the plurality of protrusions;
- a plurality of moving light emitting devices, the moving light emitting devices being positioned among the plurality of protrusions;
- and
- a plurality of connection wirings connecting among the plurality of fixed light emitting devices and the plurality of moving light emitting devices.
A stretchable display, comprising:
- a stretchable substrate;
- a plurality of fixed light emitting devices attached to the stretchable substrate;
- a plurality of moving light emitting devices positioned over the stretchable substrate, while being spaced apart from the stretchable substrate;
- and
- a plurality of connection wirings connecting the plurality of fixed light emitting devices and the plurality of moving light emitting devices.
A manufacturing method of a stretchable substrate, the method comprising:
- forming a plurality of light emitting devices and a plurality of connection wirings connecting therebetween on a carrier substrate;
- separating the plurality of light emitting devices and the plurality of connection wirings from the carrier substrate;
- forming a stretchable substrate including a plurality of protrusions protruding above a flat part of the stretchable substrate;
- elongating the stretchable substrate to increase intervals among the plurality of protrusions;
- attaching the plurality of light emitting devices and the plurality of connection wirings to the elongated stretchable substrate;
- and
- contracting the stretchable substrate.
