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 designing a set of display elements, comprising:

a) selecting a set of light-emitting elements, each light-emitting element of said set capable of emitting light of a respective selected wavelength band;

b) determining a preferred arrangement of said light-emitting elements, wherein said preferred arrangement specifies the position of light-emitting elements capable of emitting light of each of said selected wavelength bands relative to light emitting elements capable of emitting light of other of said selected wavelength bands; and

c) designing an attribute set for each said light-emitting element of said set of light-emitting elements, each said attribute set adapted to promote self-organization of said set of display elements according to said preferred arrangement.

2. The method of claim 1, wherein said set of light emitting elements includes a plurality of types of light emitting elements, wherein each type of light emitting element is characterized by a respective one of the attribute sets and is capable of emitting light of a respective selected wavelength band, and wherein according to said preferred arrangement certain types of elements are attracted to and associate with certain other types of elements.

3. The method of claim 2, wherein elements are attracted to elements different than their own type.

4. The method of claim 1, wherein according to said preferred arrangement, a first type of elements is repelled from and avoids associating with a second type of elements.

5. The method of claim 4, wherein the first type of element and the second type of element are the same type of element.

9. The method of claim 2, wherein said set of light-emitting elements include three different types of elements and wherein said three types of elements self-organize into triads in said preferred arrangement, each triad including one of each of said three types of elements.

10. The method of claim 2, wherein said set of light-emitting elements includes between two and ten different types of light-emitting elements.

33. The method of claim 1, wherein said preferred arrangement comprises a pattern that is at least one of a pattern having short-range order, a pattern having long-range order, or a repeating pattern.

11. A display element suitable for assembly into a multi-color display having a plurality of elements, comprising:

a) A light emitting element capable of emitting light in a respective range corresponding to one or more of the colors in response to a control signal; and

b) A carrier in which said light emitting element is housed, said carrier having defined shape and surface properties, the defined shape and surface properties being selected to preferentially locate the display element with respect to other display elements in a desired color pattern to form the multi-color display.

12. The display element of claim 11, wherein said light emitting element comprises an organic or inorganic wavelength converter.

13. The display element of claim 11, wherein said light emitting element is a wavelength converter, phosphor, fluor, laser diode, light emitting diode, organic light emitting diode, polymer light emitting diode, quantum dot, polymer, electroluminescent device, chemoluminescent device, or nonlinear optical material.

14. The display element of claim 11, wherein said light emitting element is responsive to a control signal.

21. The display element of claim 11, wherein said light emitting element is formed integrally with said carrier.

22. The display element of claim 11, wherein said light emitting element is formed separately from said carrier and subsequently integrated into said carrier.

23. The display element of claim 22, wherein said carrier comprises a coating formed on said light emitting element.

24. The display element of claim 22, wherein said carrier comprises a structure into which said light emitting element is placed.

25. The display element of claim 22, wherein said carrier comprises a structure to which said light emitting element is attached.

26. The display element of claim 11, further comprising at least one contact for forming an electrical or optical connection with a substrate or another display element.

34. The display element of claim 14, wherein said light emitting element is responsive to a control signal by emitting light or by stopping emitting light.

35. The display element of claim 14, wherein said control signal includes at least one of electromagnetic radiation, an electrical potential, or an electrical current.

36. The display element of claim 11, wherein said carrier comprises at least one of a polymeric material and a semiconductor material.

37. The display element of claim 11, further comprising at least one of a power signal input, a receiver coil for receiving power input inductively, or a battery.
