Abstract
A display device includes a backlight and a display panel on the backlight. The backlight includes a light source to provide a first light, and an optical wavelength converter to receive the first light and emits a second light. The optical wavelength converter includes a light emitting part having a plurality of excitation light emitting bodies to be excited by receiving the first light, and thereby emit the second light, and a light absorbing part including a plurality of absorbers provided on the light emitting part to receive the second light and absorb a portion of the second light having a wavelength of about 550 nm to about 650 nm.
Claims17
A display device, comprising:
- a backlight;
- and
- a display panel on the backlight, wherein the backlight includes:
- a light source to provide a first light;
- and
- an optical wavelength converter to receive the first light and emit a second light, the optical wavelength converter including;
- a light emitting part having a plurality of excitation light emitting bodies to be excited by receiving the first light, and thereby emit the second light, and
- a light absorbing part including a plurality of absorbers provided on the light emitting part to receive the second light and absorb a portion of the second light having a wavelength of about 550 nm to about 650 nm.
A display device, comprising:
- a backlight;
- and
- a display panel on the backlight, the backlight including:
- a light guide plate;
- a light source on at least a side surface of the light guide plate, the light source to provide a first light to the light guide plate;
- and
- a light absorbing sheet having a plurality of absorbers,
- wherein:
- the light guide plate includes a plurality of excitation light emitting bodies to be excited by receiving the first light, and thereby emit a second light, and
- the absorbers to receive the second light from the light guide plate and to absorb a portion of the second light having a wavelength of about 550 nm to about 650 nm.
A display device, comprising:
- a backlight;
- and
- a display panel provided on the backlight, wherein the backlight includes:
- a light source;
- a diffusion plate on the light source, the diffusion plate to receive a first light from the light source, the diffusion plate including a plurality of excitation light emitting bodies that are excited when the first light is incident thereon, and thereby emit the second light;
- and
- a light absorbing sheet having a plurality of absorbers to receive the second light from the diffusion plate and to absorb a portion of the second light having a wavelength of about 550 nm to about 650 nm.
