| 20090122518 | Surface Light Source Device and Image Display Unit - A surface light source device includes a first light source disposed so as to face a reflecting surface of a reflecting member, a second light source having spectrum selectivity different from that of the first light source, a light diffusing member configured to diffuse light rays emitted from the first and second light sources, and a transparent light control member disposed between the first light source and the light diffusing member so as to face the first light source and the light diffusing member. The light control member directs the light rays emitted from the first and second light sources in predetermined directions. The second light source faces an outer peripheral surface of the light control member. The light ray emitted from the second light source is directed by the light control member inside the light control member so as to be output towards the light diffusing member. | 05-14-2009 |
| 20090185364 | SURFACE LIGHT SOURCE DEVICE AND IMAGE DISPLAY APPARATUS - A surface light source device includes a light source facing a reflective surface of a reflecting member, and a light-controlling member composed of a transparent material and disposed across the light source from the reflecting member in such a manner as to face the reflective surface, the light-controlling member guiding light emitted from the light source in a predetermined direction. The light-controlling member has on a surface thereof remote from the reflective surface projections arranged on a plane. The projections have profiles of at least one kind, each having a symmetry axis or a symmetry plane. The symmetry axes or the symmetry planes of the projections are tilted at a predetermined angle with respect to a direction in which the light controlling member faces the reflecting member. | 07-23-2009 |
| 20090262521 | Surface light source device and image display device - A surface light source device includes a diffusing member which diffuses light, a reflective member which reflects light, plural light sources provided aligned in a flat manner between the diffusing member and the reflective member, and a light control member provided between the plural light sources and the reflective member as well as arranged in a state that a gap is imposed between the reflective member and the light control member, which has a light-guiding function of guiding part of light emitted from respective light sources in an alignment direction of the light sources, in which the light control member has a rugged structure portion in which geometric shapes in cross section are continuously formed on at least one surface. | 10-22-2009 |
| 20100103652 | SURFACE LIGHT SOURCE DEVICE, MANUFACTURING METHOD OF THE SAME, AND IMAGE DISPLAY DEVICE - A surface light source device includes: a light source; a diffusion member that diffuses light; and reflection means provided on a side opposite to the diffusion member with the light source interposed therebetween for reflecting light emitted from the light source toward the diffusion member, wherein the reflection means is formed by layering a plurality of optical components and the plurality of optical components are stopped by each other with stopper means. | 04-29-2010 |
| 20110074935 | Image Display Viewing System and Image Display Device - Systems, methods, and display apparatuses consistent with the invention may generate control signals to control n light-passing devices such that the n light-passing devices each are sequentially operated between ON and OFF states, and such that each of the n light-passing devices are in the ON state no less than 1/n of the viewing period. This may allow different images to be viewed through different light-passing devices. The embodiments may be used, for example, to present a three-dimensional image to a viewer or to present different videos to different viewers. | 03-31-2011 |
| 20110074939 | Image Display Viewing System, Optical Modulator and Image Display Device - There is provided an image display viewing system including an image display device including a signal control portion that receives input of an image signal and outputs a signal that causes each of multiple different images to be displayed at least twice consecutively, and a display panel to which the signal output from the signal control portion is input and which alternately displays each of the multiple different images at least twice consecutively, and an optical modulator including a liquid crystal layer on which an image having a predetermined polarization direction output from the image display device and external light having random polarization are incident, and which periodically changes the polarization direction of the incident light, and a polarizing plate on which light emitted from the liquid crystal layer is incident and which has a polarization axis in a predetermined direction. | 03-31-2011 |
| 20110149053 | Image display device, image display viewing system and image display method - An image display device includes a display panel that periodically displays different images, a shutter control portion that generates timing signals for driving shutters for a right eye and a left eye, in synchronization with the periodical display of the display panel, with respect to glasses for viewing images, the glasses being provided with the shutters for the right and left eye, a backlight that includes a light guide plate of a size corresponding to a display area of the display panel and light sources that are provided on two opposing side faces of the light guide plate and that irradiates the display panel from a rear side of the display panel, and a backlight control portion that causes the respective light sources that are provided on the two opposing side faces to blink at different timings during an opening period of the shutters. | 06-23-2011 |
| 20120133657 | REQUIREMENT STRUCTURE DISPLAY APPARATUS AND COMPUTER READABLE MEDIUM - A requirement structure display apparatus includes a graph display information generation unit that generates graph display information representing a graph constituted by the parent-child relationships; a first specification acceptance unit that accepts a specification of the requirement data or the strategy data of an object in interest in the graph represented by the graph display information generated by the graph display information generation unit; a part-in-interest display information generation unit that generates part-in-interest display information; and a display control unit that controls a display by a display unit so as to be switched from a display based on the graph display information generated by the graph display information generation unit to a display based on the part-in-interest display information generated by the part-in-interest display information generation unit based on the object in interest accepted by the first specification acceptance unit. | 05-31-2012 |
