Abstract

An optical package structure includes a light transmittable member, a bonding structural member, and an optical element. The bonding structural member includes a first bonding layer and a second bonding layer to form a light-scattering structure. The first bonding layer is connected to a bonding surface of the light transmittable member. An inner side of the first bonding layer includes a plurality of first protruded portions. An inner side of the second bonding layer includes a plurality of second protruded portions. The second protruded portions and the first protruded portions are arranged in a staggered manner. The bonding structural member includes the first bonding layer or the light-absorption member. The light-absorption member is filled in concaved portions of the first bonding layer. The optical element is connected to the bonding structural member, and is spaced apart from the light transmittable member.

Dependent claims

An optical package structure, comprising:

a light transmittable member having a bonding surface;
a first bonding layer having an enclosed shape and connected to the bonding surface of the light transmittable member, wherein the first bonding layer is made of an opaque material, the first bonding layer includes a first inner circumference and a plurality of first protruded portions, and the plurality of first protruded portions protrude inwardly from the first inner circumference;
a second bonding layer having an enclosed shape, wherein the second bonding layer is opposite to the light transmittable member and connected to the first bonding layer, the second bonding layer is made of an opaque material, the second bonding layer includes a second inner circumference and a plurality of second protruded portions, and the plurality of second protruded portions protrude inwardly from the second inner circumference;
wherein the plurality of second protruded portions and the plurality of first protruded portions are arranged in a staggered manner;
and
an optical element connected to the second bonding layer, wherein the optical element and the light transmittable member are spaced apart from each other.
