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

1-104. -104. (canceled)

105. A multi-element display comprising a plurality of display elements in a self-organized array disposed on a substrate, said plurality of display elements comprising two or more types of display elements self-organized by type into a preferred arrangement in which the position of display elements of each type relative to display elements of other types is specified, display elements of each type characterized by at least one surface or shape property that promotes association with other display elements to form said preferred arrangement.

106. The multi-element display of claim 105, wherein said substrate comprises a surface having a surface characteristic that influences the spatial distribution of display elements of different types on said surface.

107. The multi-element display of claim 106, wherein said surface characteristic includes one or more of a surface charge, surface energy, magnetic property, binding affinity of a biomolecule, surface shape, or surface texture.

108. The multi-element display of claim 105, wherein said substrate includes a rigid material.

109. The multi-element display of claim 106, wherein said substrate includes a flexible material.

110. The multi-element display of claim 105, wherein said substrate includes a fluid.

111. The multi-element display of claim 105, wherein each said type of display element has a light spectral characteristic.

112. The multi-element display of claim 111, wherein said light spectral characteristic comprises a light absorption spectrum.

114. The multi-element display of claim 111, wherein said light spectral characteristic comprises a light reflection spectrum.

115. The multi-element display of claim 105, wherein each said type of display element differs from at least one other type of display element by one or more characteristics including size, shape, wavelength band envelope, spectral width, power, emission pattern, polarity, response speed, or linearity.

116. The multi-element display of claim 105, wherein display elements of different types are distributed spatially non-uniformly within said display.

117. The multi-element display of claim 116, wherein display elements are distributed spatially non-uniformly with respect to size.

118. The multi-element display of claim 116, wherein display elements are distributed spatially non-uniformly with respect to wavelength band.

119. The multi-element display of claim 105, wherein said at least one surface or shape property comprises a surface charge.

120. The multi-element display of claim 105, wherein said at least one surface or shape property comprises a surface energy.

121. The multi-element display of claim 105, wherein said at least one surface or shape property comprises a magnetic property.

127. The multi-element display of claim 105, wherein display elements of each type are characterized by a combination of characteristic shape and characteristic surface property adapted for forming preferred associations with one or more other types of display element with a degree of preference that depends upon the type of display element.

128. The multi-element display of claim 105, configured as at least one of a television screen, a computer monitor, a video screen, a sign, a decorative item, an item of apparel, a decorative pattern region on an item of manufacture, or a functional pattern region on an item of manufacture.

129. The multi-element display of claim 105, including at least one spacer element located between two or more of said display elements.

130. The multi-element display of claim 129, wherein said at least one spacer element is characterized by at least one surface or shape property that promotes association of said spacer element with said display elements to move to a preferred location with respect to said plurality of display elements within said preferred arrangement.
