20080252861 | Rear projection type display apparatus - A rear projection type display apparatus includes a base in which an optical unit and an electrical circuit are accommodated and which has an opening at a rear side thereof, and a cabinet which supports a mirror and a screen and which is mounted to an upper side of the base. The base has a first connecting portion provided along at least one side of the opening, and the cabinet has a second connecting portion which engages the first connecting portion of the base along at least one side of the opening. One of the first connecting portion and the second connecting portion has a cross sectional shape which includes two facing inner walls and which is opened in one direction. | 10-16-2008 |
20120235891 | LIQUID CRYSTAL DISPLAY DEVICE - A liquid crystal display device has a first backlight unit and a second backlight unit. The first backlight unit includes a first optical member that transmits light incident from the second backlight unit, converts light output from a light source to light having a narrow-angle directional distribution, and radiates the converted light toward the rear surface of the liquid crystal display panel. The second backlight unit includes a second optical member that converts light output from a light source to light having a wide-angle directional distribution, and radiates the converted light toward the rear surface of the liquid crystal display panel. | 09-20-2012 |

20130033901 | BACKLIGHT DEVICE AND LIQUID CRYSTAL DISPLAY APPARATUS - A planar light source device includes a first light source for emitting a first light ray having a punctate spatial luminance distribution; a second light source for emitting a second light ray; a first spatial luminance distribution conversion portion for changing the first light ray to a linear spatial luminance distribution; a second spatial luminance distribution conversion portion for changing a spatial luminance distribution of the first and second light rays to a planar spatial luminance distribution; wherein the first light ray is a laser light; the second light ray has a divergence angle larger than the divergence angle of the first light ray when the first light ray is emitted from the first light source; and a slow-axis direction of the first light ray entering the second spatial luminance distribution conversion portion is parallel to an outgoing direction of the planar light. | 02-07-2013 |
20160054506 | SURFACE LIGHT SOURCE DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE - A surface light source device includes a laser beam source, a laser beam guide rod for converting a laser beam into first linear light, an LED light source, an LED light guide rod for converting LED light into second linear light, a reflecting bar having a reflecting region for reflecting part of the first linear light and the second linear light and a transmitting region for transmitting a residual part of the first linear light and the second linear light, and a light reflecting portion formed in a box shape and having an opening portion with an emission side opened and a reflecting surface on an inside of the box shape. In the first linear light and the second linear light, part thereof is reflected by the reflecting region and the reflecting surface and a residual part is transmitted through the transmitting region and is emitted from the opening portion. | 02-25-2016 |
20160054517 | SURFACE LIGHT SOURCE DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE - A surface light source device includes a laser beam source, a laser beam guide rod for converting a laser beam into first linear light, an LED light source, an LED light guide rod for converting LED light into second linear light extended in the same direction as the first linear light, a reflecting bar for reflecting the first linear light and the second linear light, and a light reflecting portion formed in a box shape and having an opening portion with an emission side opened and a reflecting surface on an inside of the box shape. The first linear light and the second linear light are reflected by the reflecting bar and the reflecting surface, and are emitted from the opening portion. | 02-25-2016 |
20160054623 | SURFACE LIGHT SOURCE DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE - A surface light source device includes a plurality of LEDs for emitting a plurality of light having different colors, and a light guide body for mixing the colors of the plurality of light and emitting light having colors mixed. The light guide body includes a light incident portion for causing the plurality of light to be individually incident, and a light emitting portion provided beside the light incident portion and changing propagation angles of the plurality of light which is incident from the light incident portion and propagated into the light guide body to mix colors, thereby controlling a quantity of light emission from the light guide body and a light emitting position. | 02-25-2016 |
20160109633 | SURFACE LIGHT SOURCE DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE - A surface light source device includes a first light source for emitting first light, a first light guide rod for causing the first light to be incident thereon and converting the first light into first linear light, a second light source for emitting second light having a greater divergence angle than the first light, and a second light guide rod for converting the second light into second linear light extended in the same direction as the first linear light. Moreover, the surface light source device includes a reflecting bar disposed on an emitting side of the planar light from the first and second light guide rods, and a reflecting portion taking such a box shape as to have an internal wall serving as a reflecting surface, and having an opening portion on a surface at the emitting side of the planar light. | 04-21-2016 |
