Display tile structure and tiled display
First Claim
1. A method of making a display tile, comprising:
- providing a tile substrate having a structure side;
disposing one or more light-emitting diodes (LEDs) on and in direct contact with the structure side of the tile substrate, each LED having a light-emitting side adjacent to the structure side to emit light through the tile substrate and an opposed connection side with first and second electrodes for providing electrical power to the LED to cause the LED to emit light;
forming a tile layer on or over the one or more LEDs and structure side of the tile substrate and exposing the first and second electrodes, the tile layer having an emitter side adjacent to the structure side of the tile substrate and a backplane side opposite the emitter side, the tile layer including a layer of light-absorbing material disposed in the tile layer on and in direct contact with the tile substrate and only partially encapsulating the one or more LEDs;
forming an electrically conductive first tile micro-wire electrically connected to the first electrode and an electrically conductive second tile micro-wire electrically connected to the second electrode, the first and second tile micro-wires disposed only on a side of the layer of light-absorbing material opposite the tile substrate and the first and second tile micro-wires not extending to the edges of the tile substrate; and
forming an exposed conductive first tile contact pad electrically connected to the first tile micro-wire and an exposed conductive second tile contact pad electrically connected to the second tile micro-wire, wherein the one or more LEDs comprise a plurality of semiconductor layers and the first and second electrodes are disposed on a common side of the plurality of semiconductor layers opposite the emitter side of the tile layer and wherein the first and second tile micro-wires and first and second tile contact pads are disposed only on a side of the layer of light-absorbing material opposite the tile substrate on the backplane side of the tile layer, and the first and second tile contact pads disposed on a portion of the first and second tile micro-wires that are in contact with the layer of light-absorbing material.

Abstract
A display tile structure includes a tile layer with opposing emitter and backplane sides. A light emitter having first and second electrodes for conducting electrical current to cause the light emitter to emit light is disposed in the tile layer. First and second electrically conductive tile micro-wires and first and second conductive tile contact pads are electrically connected to the first and second tile micro-wires, respectively. The light emitter includes a plurality of semiconductor layers and the first and second electrodes are disposed on a common side of the semiconductor layers opposite the emitter side of the tile layer. The first and second tile micro-wires and first and second tile contact pads are disposed on the backplane side of the tile layer.
