Abstract
The optical film includes a film body and a two-dimensional grating structure. The film body has a top surface. The two-dimensional grating structure is on the top surface of the film body, in which the two-dimensional grating structure includes an array of micro-structures in a first dimension and a second dimension intersecting the first dimension, the micro-structures are arranged as plural groups repeated by a first period in a first period direction, and at least two of the micro-structures in each of the groups are arranged in a second period in a second period direction, in which the second period is less than the first period.
Claims18
An optical film, comprising:
- a film body having a top surface;
- and
- a two-dimensional grating structure on the top surface of the film body, wherein the two-dimensional grating structure comprises an array of micro-structures in a first dimension and a second dimension intersecting the first dimension, the micro-structures are arranged as a plurality of groups repeated by a first period in a first period direction, and at least two of the micro-structures in each of the groups are arranged in a second period in a second period direction, wherein the second period is less than the first period.
An optical film, comprising:
- a film body having a top surface and a bottom surface;
- a first one-dimensional grating-structure disposed on the top surface of the film body, wherein the first one-dimensional grating-structure has a plurality of first micro-structures arranged in a first dimension, wherein the first micro-structures are arranged as a plurality of groups repeated by a first period in a first period direction, and at least two of the first micro-structures in each of the groups are arranged in a second period, wherein the second period is less than the first period;
- and
- a second one-dimensional grating-structure disposed on the bottom surface of the film body, wherein the second one-dimensional grating-structure has a plurality of second micro-structures arranged in a second dimension intersecting the first dimension.
