1. 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 indoor 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.
