Abstract
The present invention provides a light extraction film including a micro-lens array film and at least one optical film. The micro-lens array film has a first surface and a second surface opposite to each other, and has a plurality of micro-lenses disposed on the first surface. The optical film covers the first surface, and the optical film includes a plurality of optical particles and a thin film layer. The optical particles are disposed in the thin film layer.
Claims19
A light extraction film, comprising:
- a Micro-Lenses Array (MLA) film, having a first surface and a second surface opposite to each other and having a plurality of micro-lenses disposed on the first surface;
- and
- at least one optical film covering the first surface, the optical film comprising a plurality of optical particles and a thin film layer, and the optical particles being disposed in the thin film layer.
A light emitting device, comprising:
- a light source, having a light-emitting surface;
- a MLA film, disposed on the light-emitting surface of the light source, the MLA film having a first surface and a second surface opposite to each other and having a plurality of micro-lenses disposed on the first surface, wherein the second surface contacts the light-emitting surface;
- and
- at least one optical film covering the first surface, the optical film comprising a plurality of optical particles and a thin film layer, and the optical particles being disposed in the thin film layer.
