Abstract: A quasi-crystal organic light-emitting display panel including a first electrode layer, an organic light-emitting layer, a second electrode layer, a buffer layer, a 10-fold quasi-crystal layer and a package cover is provided. The organic light-emitting layer is located on the first electrode layer. The second electrode layer is located on the organic light-emitting layer. The buffer layer is located on the second electrode layer. The 10-fold quasi-crystal layer is located on the buffer layer. The package cover is located on the 10-fold quasi-crystal layer. A method for simulating optical efficiency of the quasi-crystal organic light-emitting display panel is also provided.

Abstract: An optical film adapted to be disposed over a light source is provided. The optical film includes a substrate, a plurality of columnar prismatic units, and a plurality of lenticular lenses. The substrate has a first surface and a second surface, wherein the first surface is located between the second surface and the light source. The columnar prismatic units comprises a plurality of columnar prisms protruding from the first surface or a plurality of prismatic recesses indented in the first surface, and the plurality of columnar prismatic units are arranged along a first direction and respectively extend along a second direction. The lenticular lenses are protruded from the second surface. The lenticular lenses are arranged along the first direction and respectively extend along the second direction. A light source module is also provided.
