Abstract

The present invention provides systems, and methods for manufacturing polarized light emitting semiconductor packages, comprising the disposition of a first bonding solution about (a) a first light emitting element and (b) a first polarizing element, wherein the first polarizing element transmits linearly polarized light in a first directionality. A first energy is applied to polymerize the first bonding solution, thereby encapsulating the first polarizing element and a first light emitting element in a first semiconductor package. A second bonding solution is disposed about (a) a second light emitting element and (b) a second polarizing element, wherein the second polarizing element transmits polarized light in a second directionality different from the first directionality, and a second energy is applied to polymerize the second bonding solution, thereby encapsulating the second polarizing element and the second light emitting element in a second semiconductor package.

Claims (19)

1. A method of manufacturing polarized light emitting semiconductor packages, comprising:

disposing a first bonding solution about (a) a first light emitting element and (b) a first polarizing element, wherein the first polarizing element transmits polarized light in a first directionality;

applying a first energy to polymerize the first bonding solution, thereby encapsulating the first polarizing element and a first light emitting element in a first semiconductor package;

disposing a second bonding solution about (a) a second light emitting element and (b) a second polarizing element, wherein the second polarizing element transmits polarized light in a second directionality different from the first directionality; and

applying a second energy to polymerize the second bonding solution, thereby encapsulating the second polarizing element and the second light emitting element in a second semiconductor package.

2. The method of claim 1 , further comprising disposing a diffuser between the first light emitting element and the first polarizing element.

3. The method of claim 1 , wherein the first light emitting element has a first color, and further including another light emitting element of a second color within the first semiconductor package.

4. The method of claim 3 , further comprising further including another light emitting element of a third color within the first semiconductor package.

5. The method of claim 4 , further comprising further including within the first semiconductor package, another light emitting element that emits a white light.

6. The method of claim 1 , further comprising providing at least one of the first polarizing elements with a downward facing abraded surface.

7. The method of claim 1 , further comprising mounting the first light emitting element and the first polarizing element on a substrate before the step of disposing a first bonding solution.

8. The method of claim 1 , further comprising mounting at least one of the first semiconductor packages and the second semiconductor packages onto a substrate.

9. The method of claim 1 , wherein at least one of the first light emitting elements and second light emitting elements is an infrared emitting semi-conductor.

10. The method of claim 9 , wherein members of the multiple first semiconductor packages are removed from a first carrier tape, and members of the multiple second semiconductor packages are removed from a second carrier tape, different from the first carrier tape.

11. The method of claim 9 , wherein members of both the multiple first and second semiconductor packages are chosen from a single carrier tape.

12. The method of claim 1 , wherein first directionality is linear.

13. The method of claim 1 , wherein first directionality is circular.

14. The method of claim 1 , wherein the first energy is different than the second energy.

15. The method of claim 1 , wherein the first bonding solution is different than the second bonding solution.
