| 20080239728 | LIGHT CONTROL DEVICE HAVING MODIFIED PRISM STRUCTURE - The light control device provides fillings in the valleys of the prism elements, be it uniformly or non-uniformly arranged, which is made of UV and/or thermal curable resins of an appropriate refractive index different from that of the prism elements. The optical performance of the original prism elements can be altered by the following approaches. First, the refractive index of the fillings can be appropriately chosen. Second, the fillings can be up to an appropriate height (but never overruns the surrounding prism elements). Third, the distribution of the height or the refractive index of the fillings across the light emission plane can be “patterned,” that is, in accordance with the planar light intensity distribution produced by the light source. | 10-02-2008 |

| 20090003001 | OPTICAL PATH DEFLECTING PLATE, SURFACE LIGHT SOURCE DEVICE AND TRANSMISSIVE IMAGE DISPLAY DEVICE - An optical path deflecting plate of the present invention, which is disposed separated from a plurality of light sources, comprises a main surface on which light from the light sources is incident, and a planar exit surface from which there exits the incident light from the light sources. The main surface comprises a plurality of prisms provided in each region of the main surface that corresponds to a region between two adjacent light sources. First prisms, among the plurality of prisms, are disposed in first and third regions of respective regions, while second prisms are disposed in a second region. The first prisms change the orientation of light from the closer light source, among the two light sources, into the direction of the normal line of the exit surface, through refraction upon incidence on the first prisms, and change the orientation of light from the farther light source, among the two light sources, into the normal line direction, through total reflection in the prisms. The second prisms change the orientation of light from both light sources into the normal line direction, through total reflection in the prisms. As a result, uniform high brightness can be ensured. | 01-01-2009 |
