Backlight assembly with thin film light pipe
View Patent ↗A backlight assembly is provided. The backlight assembly includes a light pipe assembly having a thickness of about 90 microns, a light source and a coupler that receives light from the light source and diffuses the received light from the light source into the first end of the light pipe assembly.
1. A backlight assembly comprising:
a light pipe assembly;
a light source; and
a coupler that receives light from the light source and diffuses the received light from the light source into the first end of the light pipe assembly,
wherein the coupler has a concave curvature on a side facing the light source to provide an air gap between the coupler and the light source.
2. The backlight assembly as in claim 1 wherein the concave curvature of the coupler implements a corrective lens.
3. A backlight assembly comprising:
a light pipe assembly;
a light source; and
a coupler with a lens disposed between the light source and the light pipe assembly that diffuses light from the light source into the light pipe assembly,
wherein the coupler has a concave curvature on the side facing the light source to provide an air gap between the coupler and the light source.
4. A backlight assembly comprising:
a light pipe assembly;
a light source; and
a coupler with a light receiving portion dimensioned for an angular emission characteristic of the light source,
wherein the light receiving portion has a concave curvature to provide an air gap between the coupler and the light source.
