Light source assembly
A light source assembly is provided, including a substrate; a light-emitting element disposed on the substrate; and an optical film disposed on the light-emitting element. A diffuser layer is disposed between the optical film and the light-emitting element, wherein a haze of the diffuser layer is greater than 85%, a distance between the diffuser layer and the light-emitting element is in a range from 0 mm to 10 mm, and a thickness of the light-emitting element is less than the distance.
1 . A light source assembly, comprising:
a substrate;
a light-emitting element disposed on the substrate;
an optical film disposed on the light-emitting element; and
a diffuser layer disposed between the optical film and the light-emitting element, wherein a haze of the diffuser layer is greater than 85%, a distance between the diffuser layer and the light-emitting element is in a range from 0 mm to 10 mm, and a thickness of the light-emitting element is greater than the distance.
2 . The light source assembly of claim 1 , wherein the optical film comprises a wavelength transformation layer.
3 . The light source assembly of claim 1 , further comprising a reflective layer disposed on the substrate, wherein a top surface of the reflective layer is lower than a top surface of the light-emitting element from a cross-sectional view.
4 . The light source assembly of claim 1 , wherein the optical film comprises a prism lens.
5 . The light source assembly of claim 4 , wherein the prism lens is a brightness enhancement film (BEF) or a dual brightness enhancement film (DBEF).
