Abstract
Systems and methods for hermetically sealed quantum dots that may be positioned directly on top of the LED, so that a separate film is not needed to incorporate the quantum dots into a light, display, or other LED-based device. An enclosed quantum dot package can be incorporated directly on top of an LED die and packaged in the same packaging as the LED itself. Alternatively, the LED die may be encapsulated in the LED package, and the enclosed quantum dot package may be placed on top of the encapsulated LED. Alternatively, the enclosed quantum dot package may be separate from the encapsulated LED, e.g., included in a device as a separate layer from the LED package(s).
Claims33
A system comprising:
- a light emitting diode (LED) die;
- a porous material having a plurality of pores positioned on top of the light emitting diode die;
- a quantum dot material deposited within the plurality of pores of the porous material;
- a sealant, disposed over the quantum dot material and the porous material, for hermitically sealing the quantum dot material within the plurality of pores;
- and
- LED packaging for housing the light emitting diode die, the porous material, the quantum dot material, and the sealant in a single unit.
A method for producing an LED, the method comprising:
- loading a plurality of quantum dots into a porous material;
- hermetically sealing the quantum dots within the porous material;
- positioning the porous material with the hermetically sealed quantum dots above an LED die;
- and
- encapsulating the LED die and the porous material with the hermetically sealed quantum dots in a single LED package.
A method for producing hermetically sealed quantum dots, the method comprising:
