Abstract
A light emitting module and a display device including the same are disclosed. The light emitting module including: a substrate; a plurality of light emitting units disposed on the substrate; a plurality of encapsulating elements covering the plurality of light emitting units; and a reflective layer surrounding each of the plurality of light emitting units.
Claims15
A light emitting module, comprising:
- a substrate;
- a reflective layer disposed on a surface of the substrate, wherein the reflective layer comprises a first reflective portion, a second reflective portion and a third reflective portion, a first opening is disposed between the first reflective portion and the second reflective portion, and a second opening is disposed between the second reflective portion and the third reflective portion;
- a first encapsulated light emitting unit disposed in the first opening of the reflective layer, wherein the first encapsulated light emitting unit comprises a first light emitting unit and a first encapsulating element covering the first light emitting unit;
- and
- a second encapsulated light emitting unit disposed adjacent to the first encapsulated light emitting unit, and disposed in the second opening of the reflective layer, wherein the second encapsulated light emitting unit comprises a second light emitting unit and a second encapsulating element covering the second light emitting unit,
- wherein in a direction perpendicular to the surface of the substrate, the first encapsulating element of the first encapsulated light emitting unit is not overlapped with the reflective layer, and the second encapsulating element of the second encapsulated light emitting unit is not overlapped with the reflective layer;
- wherein the second reflective portion is disposed between the first encapsulated light emitting unit and the second encapsulated light emitting unit, and the second reflective portion of the reflective layer comprises another surface opposite to the surface of the substrate, and the another surface of the second reflective portion of the reflective layer comprises a recess concaving toward the substrate.
