Patent ID: 11916168
Assignee: SEOUL VIOSYS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A light emitting device, comprising:
a substrate having a light emission region and a light shield region;
a light emitter disposed on the substrate and comprising at least one active layer;
a light shield layer disposed on the substrate and defining the light shield region; and
a first insulation layer surrounding the light emitter, the first insulation layer comprising photoresist, epoxy, PDMS (polydimethylsiloxane), or a black matrix,
wherein the light emission region overlaps with the light emitter,
wherein the substrate has a roughened surface overlapping at least a portion of the light emission region, and a portion of the roughened surface is covered with the light shield layer,
wherein light emitted from the at least one active layer is configured to be transmitted through the substrate,
wherein the light emitter has inclined sidewalls such that a width of the light emitter closer to the substrate is greater than a width the light emitter further away from the substrate, and
wherein the light shield layer comprises metallic material, photoresist, epoxy, PDMS (polydimethylsiloxane), or a black matrix.
