Abstract: The present invention discloses a method of forming an optical sheet. The optical sheet comprises a substrate and a film. The substrate has a first surface and a second surface opposite to the first surface. The film has a third surface and a fourth surface opposite to the third surface. The third surface of the film is on the first surface of the substrate. The fourth surface of the film comprises a structure corresponding to a combination of a plurality of first convex shapes and a plurality of second convex or concave shapes superimposed on the plurality of first convex shapes.

Abstract: The present invention discloses a method of forming an optical sheet. The method comprises: providing a mold having a first surface; forming a plurality of first concave shapes on the first surface of the mold such that the first surface of the mold is changed to a second surface of the mold; forming a plurality of second shapes on the plurality of first concave shapes such that the second surface of the mold is changed to a third surface of the mold; and using the third surface of the mold to emboss a film on a substrate to form a composite structure corresponding to the combination of the plurality of first concave shapes and the plurality of second shapes.

Abstract: The present invention discloses an optical assembly used in the backlight module. The optical assembly comprises: a first optical film having a first surface; an adhesive layer having a second surface and a third surface opposite to the second surface, wherein the second surface of the adhesive layer is disposed on the first surface of the first optical film; and a diffusing sheet having a fourth surface comprising a plurality of first microstructures and a plurality of second microstructures, wherein each of the plurality of second microstructures extends along a first direction, wherein the maximum height of the plurality of second microstructures is greater than that of the plurality of first microstructures so as to bond the plurality of second microstructures to the third surface of the adhesive layer.
