Abstract

Various embodiments of methods and systems for designing and constructing displays from multiple light emitting elements are disclosed. Display elements having different light emitting and self-organizing characteristics may be used during display assembly.

Claims

1. A method of forming a display, comprising:

disposing a plurality of display elements of a plurality of types onto a substrate, each of said plurality of types of display elements having a characteristic comprising at least one of a characteristic shape or characteristic surface property configured for forming preferred associations with one or more other types of display elements with a degree of preference that depends upon the type of display element; and

inducing relative movement of display elements and said substrate sufficient to produce association of at least a portion of said display elements with other said display elements to form a group of associated display elements, wherein said induced movement is sufficient to permit said display elements to self-organize to form preferred associations within said group of associated display elements.

2. The method of claim 1, wherein each of said types of display elements in said plurality of types has a characteristic comprising at least one of a characteristic shape or characteristic surface property selected to provide a relatively lower preference for said display element forming associations with other display elements of the same type than for forming associations with other display elements of a different type.

3. The method of claim 1, wherein said characteristic comprises a surface charge.

4. The method of claim 1, wherein said characteristic comprises a surface energy.

5. The method of claim 1, wherein said characteristic comprises a magnetic property.

6. The method of claim 1, wherein said characteristic comprises a binding affinity of a biomolecule.

7. The method of claim 6, wherein said biomolecule includes a nucleotide sequence.

8. The method of claim 6, wherein said biomolecule includes an amino acid sequence.

9. The method of claim 1, wherein said characteristic comprises a concavity.

10. The method of claim 1, wherein said characteristic comprises a convexity.

11. The method of claim 1, wherein one or more of said types of display elements in said plurality of types has a characteristic comprising at least one of a characteristic shape and characteristic surface property adapted for forming preferred associations with one or more other types of display elements with a degree of preference that depends upon the type of display element.

12. The method of claim 1, including pouring said elements onto said substrate.

13. The method of claim 1, including spraying said elements onto said substrate.

14. The method of claim 1, wherein said relative movement is random.

15. The method of claim 1, wherein inducing said relative movement of said display elements and said surface includes shaking said surface.

16. The method of claim 1, wherein inducing relative movement of said display elements and said surface includes vibrating said surface.

17. The method of claim 1, including connecting said group of associated display elements to each other.

18. The method of claim 17, including connecting said group of associated display elements to each other by at least one of heat, vibration, pressure, chemical treatment, or an adhesive to form a connected group of associated display elements.

19. The method of claim 18, comprising removing said connected group of associated display elements from said substrate as a unit.

20. The method of claim 19, comprising transferring said unit to a different substrate.

21. The method of claim 1, including connecting said group of associated display elements to said substrate.

22. The method of claim 18, including connecting said group of associated display elements to said substrate by at least one of heat, vibration, pressure, chemical treatment, or an adhesive.

23. The method of claim 22, wherein connecting said group of associated display elements includes forming connections for transmitting data or power.

24. The method of claim 22, wherein connecting said group of associated display elements includes forming connections for transmitting thermal energy.
