20110305038 | PLANAR LIGHT SOURCE DEVICE AND DISPLAY APPARATUS - A planar light source device including: a point light source; and a light guide plate, wherein the light guide plate includes: an emitting surface; an opposite emitting surface; and a side surface that connects the emitting surface and the opposite emitting surface; wherein the point light source is arranged adjacent to the side surface of the light guide plate, wherein the light guide plate has a cylindrical hole that is formed at a position, which corresponds to the position where the point light source is arranged, and wherein the hole forms an opening at the side surface to emit a portion of the light to the outside of the light guide plate, the portion of the light is emitted by the point light source and the portion of the light being a portion that was not totally reflected at the side surface. | 12-15-2011 |
20120127400 | ILLUMINATION DEVICE AND LIQUID CRYSTAL DISPLAY - It is an object of the invention to provide a technique capable of suppressing variations in luminance in the vicinity of a light entrance surface of a light guide plate. An illumination device includes a point light source, and a light guide plate having a side surface serving as a light entrance surface opposed to the point light source, and a main surface serving as a light exit surface. The light entrance surface of the light guide plate is provided with unevenness formed by arraying at predetermined pitches a plurality of protrusions each projecting from the light entrance surface and extending in a direction perpendicular to the light exit surface. Each of the top surface and the bottom surface of the unevenness is provided with a plurality of micro protrusions each extending in the direction perpendicular to the light exit surface and having a height smaller than the above protrusion. | 05-24-2012 |
20120182759 | PLANAR LIGHT SOURCE APPARATUS AND DISPLAY APPARATUS USING THE SAME - A planar light source apparatus includes a light source substrate including: a point light source; a mount part, on which the point light source is mounted; and a wiring part, which has a wiring pattern to supply power to the point light source; a frame including: one face, along which the mount part of the light source substrate is arranged: and an attachment part, which is formed on the one face, wherein the light source substrate has either of a cutout or hole at a position corresponding to the attachment part of the frame, and wherein an area of the wiring part is continuously provided from the mount part and is bent with respect to the one face. | 07-19-2012 |
20140009910 | DISPLAY DEVICE - A recessed portion is formed in a side face of a display device. An elastic body is provided in a recessed portion. The elastic body is elastically deformed to fix the display device to a housing when the display device is mounted in a predetermined-shaped space of the housing. | 01-09-2014 |
20150103272 | ELECTRIC DEVICE - An electric device of this disclosure includes: a display device including: a display element configured to display an image; a light source; an intermediate frame configured to hold the light source; and a planar light source device configured to illuminate the display element, and a proximity sensor arranged at an outside of the display device and configured to detect approaching information to the display device. The intermediate frame is provided with an extension part extending outwardly from the display device and a holding part configured to integrally hold the proximity sensor is formed at the extension part. | 04-16-2015 |
20150131325 | DISPLAY DEVICE - A display device includes a display element, a planar light source device disposed on an opposite side of a display surface of the display element, a protective plate disposed on a display surface side of the display element, and a black frame member covering a peripheral edge part on a front surface of the protective plate, sandwiching the protective plate from both sides in a thickness direction, and having a decorated front surface. | 05-14-2015 |
