Abstract

A display that contains a sparse array of light-emitting diodes (LEDs), including a related system and method of fabrication are disclosed. The display includes at least one panel disposed in or on a transparent material to provide a display on one or both sides of the material. Each tile has a transparent flexible substrate, a sparse array of LEDs disposed on the transparent flexible substrate, a rigid substrate adhered to the transparent flexible substrate via an adhesive layer in which the sparse array of LEDs is encapsulated, and a driver disposed on an edge of the tile and configured to drive the LEDs. The LEDs are sparse enough to enable information to be displayed through the transparent material while still enabling a viewer to see through the transparent material.
