Sparse led array applications

A sparse display, comprising:

• at least one tile configured to display information, the at least one tile disposed at at least one location within an outdoor substantially transparent material, each of the at least one tile including:
• a substantially transparent flexible substrate;
• a sparse array of light-emitting diodes (microLEDs) disposed on the substantially transparent flexible substrate, a distance between microLEDs of the sparse array configured to display at least one of alphanumeric and image information while providing visibility through the substantially transparent material, a surface area of light-producing areas of the microLEDs being at most about 1% of a surface area of the sparse array;
• a substantially transparent rigid substrate adhered to the substantially transparent flexible substrate via an adhesive layer in which the sparse array of microLEDs is encapsulated;
• and
• at least one driver disposed on an edge of the tile and configured to drive the microLEDs of the tile.

A sparse display, comprising:

• at least one tile configured to display information, the at least one tile disposed at at least one location within a substantially transparent material, each of the at least one tile including:
• a substantially transparent flexible substrate;
• a sparse array of individually-controllable micro light-emitting diodes (microLEDs) disposed on the substantially transparent flexible substrate, a surface area of light-producing areas of the microLEDs being at most about 1% of a surface area of the sparse array;
• and
• a substantially transparent rigid substrate attached to the substantially transparent flexible substrate;
• and
• at least one of the at least one tile includes a user input configured to adjust information provided by the at least one tile or the information provided by the at least one tile is configured to be adjusted by a remote user input on a mobile device.
