Abstract

An electronic device includes a light source, at least three switching components and a light adjusting layer. The at least three switching components are disposed on the light source. The light adjusting layer is overlapped with the at least three switching components, wherein the light adjusting layer includes at least one light adjusting structure, and one light adjusting structure is corresponding to the at least three switching components and configured to adjust a light progressing direction of a light generated by the light source. The electronic device provides a first viewing-angle in a first state, the electronic device provides a second viewing-angle in a second state, and the first viewing-angle is different from the second viewing-angle.

First claim

What is claimed is:

1 . An electronic device, comprising:
a light source; at least three switching components disposed on the light source; and a light adjusting layer overlapped with the at least three switching components, wherein the light adjusting layer comprises at least one light adjusting structure, and one of the at least one light adjusting structure is corresponding to the at least three switching components and configured to adjust a light progressing direction of a light generated by the light source; wherein the electronic device provides a first viewing-angle in a first state, the electronic device provides a second viewing-angle in a second state, and the first viewing-angle is different from the second viewing-angle.

2 . The electronic device according to claim 1 , wherein the at least one light adjusting structure comprises a plurality of light adjusting structures, and the plurality of light adjusting structures are a plurality of repeated units.

3 . The electronic device according to claim 1 , wherein the at least one light adjusting structure comprises a plurality of light adjusting structures, and a recess is formed at a connection between adjacent two of the plurality of light adjusting structures.

4 . The electronic device according to claim 3 , wherein the recess has a first thickness, one of the plurality of light adjusting structures has a second thickness, the second thickness is a maximum thickness of the plurality of light adjusting structures, and the first thickness is less than the second thickness.

5 . The electronic device according to claim 1 , further comprising a medium layer overlapped with the at least one light adjusting structure.

6 . The electronic device according to claim 5 , wherein the medium layer comprises liquid crystal.

7 . The electronic device according to claim 5 , wherein the medium layer is configured to control an intensity of the light passing through the medium layer.

8 . The electronic device according to claim 1 , wherein one of the at least one light adjusting structure comprises one lens structure or multiple lens structures.

9 . The electronic device according to claim 1 , further comprising a display layer comprising the at least three switching components.
