Abstract
Light emitting diodes, display systems, and manufacturing methods are provided. In an embodiment, by way of example only, a light emitting diode (“LED”) include a die and a lens. The die is configured to emit wavelengths of light within a first predetermined spectral range. The lens is disposed on at least a portion of the die and is configured to filter the light emitted from the die such that a second predetermined spectral range is emitted from the LED.
Claims20
A light emitting diode, comprising:
- a die configured to emit wavelengths of light within a first predetermined spectral range;
- and
- a lens disposed on at least a portion of the die, the lens configured to filter the light emitted from the die such that a second predetermined spectral range is emitted from the LED.
A display system, comprising:
- a backlight assembly including:
- a substrate, and
- a plurality of light emitting diodes mounted to the substrate, each light emitting diode comprising:
- a die configured to emit wavelengths of light within a first predetermined spectral range;
- and
- a lens disposed on at least a portion of the die, the lens configured to filter the light emitted from the die such that a second predetermined spectral range is emitted from the light emitting diode.
A method of manufacturing a display system, the method comprising the steps of:
- forming a light emitting diode by forming a lens around a die configured to wavelengths within a first predetermined spectral range when energy is applied thereto, the lens comprising a material configured to filter the light of the die to allow emission of a different predetermined spectral range.
