Abstract: Embodiments of the present disclosure relate to a color conversion sheet, a backlight unit, and a display device, in which a color conversion sheet realizing white light from blue light includes a green reflection filter positioned between a green color conversion layer and a red color conversion layer, thereby independently exciting the green light and the red light and increasing the amount of green light supplied to the display panel while preventing the green light from being excited into red light. Therefore, it is possible to increase the brightness of white light supplied through the color conversion sheet and provide a backlight unit with improved luminance efficiency.

Abstract: A light-emitting audio device, an audio output device, and a display device. The light-emitting audio device includes a micro device integrated with a micro LED device and piezoelectric device. Both image display and audio output can be enabled using a single device. Audio is output using a plurality of light-emitting audio devices disposed in a plurality of subpixels, respectively. An increase in the thickness of the display device due to integrate with a audio function can be minimized. A variety of audio output functions are provided by driving the light-emitting audio devices according to areas.
