Abstract: A light emitting diode (LED) array includes a substrate with an array having a plurality of LED chips thereon, a dielectric layer, a plug, and a conductive connection layer. Each of the LED chips is isolated from another LED chip adjacent thereto by a trench. The dielectric layer covers a surface of the substrate exposed by the trench and sidewalls and partial surfaces of the LED chips adjacent to the trench. The plug fills the trench. The conductive connection layer is disposed over the plug and the dielectric layer to connect the LED chips with the LED chips adjacent thereto. Radiation emitted from one of the LED chips can be reflected by the dielectric layer and the plug, and finally reflected and output from a side of the LED chip not adjacent to the trench, thereby not affecting the adjacent LED chip and being absorbed by it.

Abstract: The present invention discloses a LED structure and a method for manufacturing the LED structure. The LED structure includes a substrate, a reflection layer, a first conducting layer, a light emitting layer, and a second conducting layer. The substrate has a plurality of grooves, and the reflection layer is disposed inside the plurality of grooves. The reflection layer is formed as a reflection block inside each of the grooves. The first conducting layer is disposed on the substrate, that is, the reflection layer is disposed between the first conducting layer and the substrate. The light emitting layer and the second conducting layer are sequentially disposed on the first conducting layer. The light emitting layer generates light when a current pass through the light emitting layer. Accordingly, the light generated by the light emitting layer can be emitted to the same side of the LED structure.
