Abstract
The present disclosure provides a display film. The display film includes a substrate and a film stack provided on the substrate, wherein the film stack sequentially includes: a first high-refractive-index layer, a transflective coating layer and a second high-refractive-index layer; and the transflective coating layer is made of at least one metal and an oxide of the metal, or at least one metal and a nitride of the metal, or at least one metal and a nitride and an oxide of the metal. The present disclosure further provides a display assembly using the display film. The display assembly of the present disclosure can display projected information.
Claims22
A display film, comprising:
- a substrate;
- and
- a film stack provided on the substrate, the film comprising:
- a first high-refractive-index layer characterized by a first refractive index of 1.8 to 2.4;
- a transflective coating layer coupled to the first high-refractive-index layer;
- and
- a second high-refractive-index layer coupled to the first high-refractive-index layer, the second high-refractive-index layer being characterized by a second refractive index of 1.8 to 2.4;
- wherein the transflective coating layer is a single layer comprising at least one metal material and a metal oxide material and/or a metal nitride material, and wherein the metal material coexists with the metal oxide material or the metal nitride material within the single layer.
