Abstract: A light emitting diode (LED) module that is configured to emit white light is provided. The LED module includes: a blue light emitting diode configured to emit blue light having a first peak wavelength of 420 nm to 465 nm; at least one wavelength conversion material that is configured to convert a portion of the blue light into converted light of a different wavelength; and a near-infrared light source configured to emit additional light having a second peak wavelength in a range of 740 nm to 900 nm and a full width at half maximum (FWHM) of 120 nm or less. The converted light, another portion of the blue light, and the additional light combine to form the white light.

Abstract: A light emitting device includes a first pixel that includes a first light-emitting structure, a first color conversion layer on the first light-emitting structure, and a first multi-layered filter on the first color conversion layer, and a second pixel that includes a second light-emitting structure, a second color conversion layer on the second light-emitting structure, and a second multi-layered filter on the second color conversion layer. Each of the first and second multi-layered filters includes at least one stack including a first film and a second film. The first multi-layered filter outputs light of a wavelength band that is different from a wavelength band of light output from the second multi-layered filter. The first multi-layered filter reflects light not output back into the first pixel and the second multi-layered filter reflects light not output back into the second pixel.
