Abstract
The present disclosure provides a light source module that includes a substrate, a plurality of light barriers on a surface of the substrate and spaced apart from each other, a plurality of light source packages on the surface of the substrate and positioned between the plurality of light barriers, and a total-reflection induction layer on the plurality of light source packages. The total-reflection induction layer has a flat surface opposite the plurality of light source packages. According to the various embodiments provided herein, the amount of light incident on a light guide plate increases, and a heat radiation effect is improved.
Claims22
A light source module, comprising:
- a substrate having a surface;
- a plurality of light barriers on the surface of the substrate and spaced apart from each other;
- a plurality of light source packages on the surface of the substrate, the light source packages being positioned between the two light barriers of the plurality of light barriers;
- and
- a total-reflection induction layer having a first surface on the plurality of light source packages and in contact with the surface of the substrate, the total-reflection induction layer extending between adjacent ones of the plurality of light source packages, the total-reflection induction layer having a flat surface that is opposite the first surface on the plurality of light source packages, the total-reflection induction layer being disposed between the light source packages with respect to a first direction, and the light source packages and the total-reflection induction layer being disposed between the light barrier in a second direction perpendicular to the first direction.
A backlight unit, comprising:
- a light source module including:
- a substrate having a surface;
- a plurality of light barriers on the surface of the substrate and spaced apart from each other;
- a plurality of light source packages on the surface of the substrate, the light source packages being positioned between the two light barriers of the plurality of light barriers;
- a total-reflection induction layer having a first surface on the plurality of light source packages, the total-reflection induction layer extending between and in contact with respective sidewalls of adjacent ones of the plurality of light source packages, the total-reflection induction layer having a flat surface that is opposite the first surface on the plurality of light source packages, the total-reflection induction layer being disposed between the light source packages with respect to a first direction, and the light source packages and the total-reflection induction layer being disposed between the light barrier in a second direction perpendicular to the first direction;
- a light guide plate positioned adjacent to the flat surface of the total-reflection induction layer;
- and
- a receiving member that receives the light source module and the light guide plate.
A method of making a light source module, comprising:
- positioning a plurality of light barriers on a surface of a substrate, the plurality of light barriers being spaced apart from each other;
- positioning a plurality of light source packages on the surface of the substrate and between the plurality of light barriers;
- and
- forming a total-reflection induction layer on the plurality of light source packages, the total-reflection induction layer extending between and in contact with respective sidewalls of adjacent ones of the plurality of light source packages, the total-reflection induction layer having a flat surface opposite the plurality of light source packages.
