Abstract

A display article includes a film formed from a stretchable plastic and including a first plurality of micro-light emitting diodes and a second plurality of micro-light emitting diodes disposed adjacent to the first plurality and embedded in the plastic. The article includes a substrate having a first portion and a second portion, and a tear seam disposed between the first and second portions. The film is attached to the substrate such that the tear seam is located between the first and second pluralities. A component includes the display article and an airbag disposed adjacent the substrate and configured for transitioning between a stowed position in which the airbag does not extend through the substrate, and a deployed position in which the airbag extends through the substrate and the film. The first and second portions are separated at the tear seam when the airbag is disposed in the deployed position.

First claim

What is claimed is:

1. A display article comprising:
a film formed from a stretchable plastic and including a first plurality of micro-light emitting diodes and a second plurality of micro-light emitting diodes disposed adjacent to the first plurality of micro-light emitting diodes;
wherein the stretchable plastic is transparent;
wherein the stretchable plastic is formed from polydimethyl siloxane;
wherein the first plurality of micro-light emitting diodes and the second plurality of micro-light emitting diodes are embedded in the stretchable plastic; and
a substrate having a first portion, a second portion disposed adjacent the first portion, and a tear seam disposed between the first portion and the second portion;
wherein the substrate is formed from polyethylene terephthalate;
wherein the film is adhered to the substrate such that the tear seam is located between the first plurality of micro-light emitting diodes and the second plurality of micro-light emitting diodes;
wherein the substrate has a first face and a second face spaced opposite the first face, wherein at least one of the first face and the second face define the tear seam; and further wherein the substrate is configured to tear along the tear seam such that the first portion separates from the second portion when a force is applied to the substrate in a direction perpendicular to the first face;
wherein the substrate is at least one of a steering wheel of a vehicle and a support pillar defining a passenger compartment of the vehicle.

2. A display article comprising:
a film formed from a stretchable plastic and including a first plurality of micro-light emitting diodes and a second plurality of micro-light emitting diodes disposed adjacent to the first plurality of micro-light emitting diodes;
wherein the first plurality of micro-light emitting diodes and the second plurality of micro-light emitting diodes are embedded in the stretchable plastic; and
a substrate having a first portion, a second portion disposed adjacent the first portion, and a tear seam having a first end and disposed between the first portion and the second portion;
wherein the substrate defines a first stress concentrator notch at the first end;
wherein the film is attached to the substrate such that the tear seam is located between the first plurality of micro-light emitting diodes and the second plurality of micro-light emitting diodes.

3. The display article of claim 2 , wherein the first stress concentrator notch is V-shaped and has a vertex, and further wherein the tear seam terminates at the vertex.

4. The display article of claim 2 , wherein the tear seam has a second end spaced apart from the first end, and further wherein the substrate defines a second stress concentrator notch at the second end.

5. A component comprising:
a display article including:
a film formed from a stretchable plastic and including a first plurality of micro-light emitting diodes and a second plurality of micro-light emitting diodes disposed adjacent to the first plurality of micro-light emitting diodes;
wherein the first plurality of micro-light emitting diodes and the second plurality of micro-light emitting diodes are embedded in the stretchable plastic;
a substrate having a first portion, a second portion disposed adjacent the first portion, and a tear seam disposed between the first portion and the second portion;
wherein the film is attached to the substrate such that the tear seam is located between the first plurality of micro-light emitting diodes and the second plurality of micro-light emitting diodes; and

an airbag disposed adjacent the substrate and configured for transitioning between:
a stowed position in which the airbag does not extend through the substrate and the film; and
a deployed position in which the airbag extends through the substrate and the film;

wherein the first portion and the second portion are separated from one another at the tear seam when the airbag is disposed in the deployed position.

6. The component of claim 5 , wherein the first portion and the second portion are joined at the tear seam when the airbag is disposed in the stowed position.

7. The component of claim 5 , wherein the airbag transitions from the stowed position to the deployed position in response to a force applied to the substrate in a direction perpendicular to the tear seam.

8. The component of claim 5 , wherein the film is separatable into at least two segments as the airbag transitions from the stowed position to the deployed position.

9. The component of claim 5 , wherein the airbag is disposed adjacent the substrate such that the substrate is disposed between the film and the airbag.

10. The component of claim 5 , wherein the stretchable plastic is transparent.

11. The component of claim 5 , wherein the substrate is a steering wheel.

12. The component of claim 5 , wherein the substrate is a support pillar defining a passenger compartment of a vehicle.
