Abstract:
The present disclosure provides a light-emitting apparatus comprising a board having a plurality of first metal contacts and a plurality of second metal contacts on a top surface; a plurality of LEDs being bonded to the board, the each of the LEDs comprising a first cladding layer on the substrate, an active layer on the first cladding layer, a second cladding layer on the active layer, an upper surface on the second cladding layer, a first metal layer, and a second metal layer, wherein the first metal layer and the second metal layer are between the active layer and the board; an opaque layer between the adjacent LEDs and comprising a polymer mixed with a plurality of inorganic particles; and an encapsulating layer on the upper surfaces and opposite to the board, wherein the encapsulating layer does not cover a side wall of the active layer; and an underfill material between the board and the plurality of LEDs, wherein the underfill material surrounds each of the first metal layer and the second metal layer.
