Abstract
A light source module includes a substrate, a light-emitting element, an optical adhesive layer and a reflective structure. The light-emitting element is disposed on the substrate. The optical adhesive layer is disposed on the substrate and covers the light-emitting element. The reflective structure is disposed in the optical adhesive layer and located above the light-emitting element. A display device using the aforementioned light source module is also provided. The light source module provided by the invention has the function of protecting the light-emitting element and improves the problem of the large thickness of the direct-type backlight module in prior art.
Claims6
A light source module, comprising a substrate, at least one light-emitting element, an optical adhesive layer and a reflective structure, wherein:
- the at least one light-emitting element is disposed on the substrate and configured to provide a light;
- the optical adhesive layer is disposed on the substrate and covers the at least one light-emitting element, and comprises a first surface and a second surface opposite to each other, the first surface faces the substrate, and the second surface is away from the substrate;
- and
- the reflective structure is disposed in the optical adhesive layer and located above the at least one light-emitting element, a part of light emitted from the at least one light-emitting element toward the reflective structure directly passes through the reflective structure, and the other part of the light is reflected by the reflective structure, wherein a width of the reflective structure is greater than or equal to a width of the at least one light-emitting element, and a thickness of the reflective structure is greatest at its center, and a thickness outside the center is less than the thickness at the center,
- wherein the light source module further comprises a reflective layer disposed on the substrate.
A display device, comprising a light source module and a display panel, wherein:
- the light source module comprises a substrate, at least one light-emitting element, an optical adhesive layer and a reflective structure, wherein:
- the at least one light-emitting element is disposed on the substrate and configured to provide a light;
- the optical adhesive layer is disposed on the substrate and covers the at least one light-emitting element, and comprises a first surface and a second surface opposite to each other, the first surface faces the substrate, and the second surface is away from the substrate;
- and
- the reflective structure is disposed in the optical adhesive layer and located above the at least one light-emitting element, a part of light emitted from the at least one light-emitting element toward the reflective structure directly passes through the reflective structure, and the other part of the light is reflected by the reflective structure, wherein a width of the reflective structure is greater than or equal to a width of the at least one light-emitting element, and a thickness of the reflective structure is greatest at its center, and a thickness outside the center is less than the thickness at the center;
- and
- the display panel is disposed on a light emitting side of the light source module, wherein the light source module further comprises a reflective layer disposed on the substrate.
