Abstract
A light emitting device package including a light emitting device; an encapsulant configured to cover the light emitting device; a first material mixed with the encapsulant to scatter light emitted from the light emitting device or convert a wavelength; and a second material mixed with the encapsulant, and disposed on a layer different from that of the first material in the encapsulant to scatter or wavelength-convert at least part of light scattered and wavelength-converted from the first material.
Claims20
A display apparatus, comprising:
- a backlight unit including a plurality of light emitting device packages configured to emit light;
- and
- a liquid crystal panel configured to display an image using the light emitted by the backlight unit,
- wherein the light emitting device packages include:
- a light emitting device;
- an encapsulant configured to cover the light emitting device;
- a first material mixed with the encapsulant to scatter light emitted from the light emitting device or convert a wavelength;
- and
- a second material mixed with the encapsulant, and disposed on a layer different from that of the first material in the encapsulant,
- wherein the first and second materials are made of the same material with different sizes or the same material with the same size, the first and second materials are made of the same material and form solid particles and hollow particles, respectively, or the first and the second material are surface-treated to have different properties.
8-10. (canceled)
A method of fabricating a light emitting device package, the method comprising:
- mixing a first and a second material having different specific gravities in an encapsulant;
- coating an encapsulant mixed with the first and the second material to cover a light emitting device;
- and
- placing the first and the second material on different layers caused by the different specific gravities,
- wherein the first and second materials are made of the same material with different sizes or the same material with the same size, the first and second materials are made of the same material and form solid particles and hollow particles, respectively, or the first and the second material are surface-treated to have different properties.
