Abstract
A white light emitting device includes: a blue light emitting diode (LED) which emits blue light; and a resin packing unit which encapsulates the blue LED, wherein the resin packing unit includes a first wavelength conversion material which, in response to being excited by the blue light, emits green light, a second wavelength conversion material which, in response to being excited by the blue light, emits red light, and a complex compound which absorbs light of a region in which the green light and the red light are mixed, the light of the region being included in white light implemented through a mixture of the green light and the red light excited together with the blue light.
Claims20
A light emitter, comprising:
- a blue light emitting diode (LED) which emits blue light;
- and
- a wavelength converter which converts a portion of the blue light into non-blue light;
- wherein the blue light and the non-blue light are combined to produce white light, the white light having a plurality of intensity peaks at a corresponding plurality of wavelengths;
- and
- wherein the light emitter further comprises an intensity reducing material which reduces an intensity of a portion of the white light between two of the intensity peaks.
A display apparatus comprising a white light emitting device, the white light emitting device comprising:
- a blue light emitting diode (LED) which emits blue light;
- and
- a resin packing unit which encapsulates the blue LED,
- wherein the resin packing unit includes a first wavelength conversion material which, in response to being excited by the blue light, emits green light, a second wavelength conversion material which, in response to being excited by the blue light, emits red light, and a complex compound which absorbs light of a region in which the green light and the red light are mixed, the light of the region being included in white light implemented through a mixture of the green light and the red light excited together with the blue light.
