20100118516 | Lens Sheet, Optical Sheet, and Backlight Unit and Display Apparatus Provided Therewith - The invention provides a novel lens sheet that can control a visual field range with high brightness while reducing side lobe generated in a conventional prism sheet, a low-profile, high-strength, high-display-quality optical sheet in which the lens sheet and a diffuser plate are optically integrated, and a backlight unit and display apparatus, in which the optical sheet is used. | 05-13-2010 |
20110090425 | OPTICAL DEVICE, UNIFORM ILLUMINATION DEVICE, OPTICAL SHEET, BACKLIGHT UNIT, AND DISPLAY UNIT - The present invention can provide an optical device, an optical uniform device, an optical sheet and a backlight unit and a display apparatus. In the present invention, a lamp image can be removed by uniformly emitting incident light from a plurality of light sources. Further, even if a distance between a light source and an optical device and between a light source and an optical uniform device are short, warpage due to heat generated from a light source does not occur. | 04-21-2011 |
20110234942 | OPTICAL COMPONENT, LIGHTING DEVICE AND DISPLAY DEVICE - One embodiment of the present invention is an optical component, including a first main surface and a second main surface wherein a plurality of two-dimensionally arranged first convex parts are arranged on the first main surface, each of the first convex parts being independent and an aspherical micro lens having an approximate semispherical shape or an approximate elliptic semispherical shape, or having a rounded tip, and a plurality of second convex parts of the height of which is lower than the height of the plurality of the first convex parts, the second convex parts comprising a lens extending in a one dimensional direction, the lens being arranged in one or two directions. | 09-29-2011 |
20120092891 | Illuminating Device and Display Device - An illuminating device acceding to the present invention has light sources, a light guide body which emits lights incident from the light sources, and a blurring structure, and, on the surface opposing to the emission surface of the light guide body, the light deflection elements which guide lights incident from the light sources toward the emission surface are formed regularly in two-dimensional direction of the first direction and second direction. The blurring structure has a function of blurring the light deflection elements regularly formed in the two-dimensional direction, and this blurring structure converts incident lights into linear lights inclined in the direction of the angle θ with respect to the first direction. | 04-19-2012 |
