| 20090097228 | OPTICAL PLATE, METHOD OF MANUFACTURING OPTICAL PLATE, BACKLIGHT ASSEMBLY AND LIQUID CRYSTAL DISPLAY DEVICE - An optical plate includes a main body plate, and a plurality of lens patterns formed on a first surface of the main body plate, wherein the lens patterns are elongated in a first direction and arranged in parallel with each other in a second direction crossing the first direction, wherein a cross section of the lens patterns form a part of an ellipse shape, the ratio of a semi-major axis to a semi-minor axis of the ellipse shape ranging from about 1.65 to about 1.75. | 04-16-2009 |
| 20090167985 | Optical Plate, Method of Manufacturing the Same and Liquid Crystal Having the Same - An optical plate having improved light scattering power, a method of manufacturing the same and a liquid crystal display having the same. An optical plate includes a base material layer, and a lens portion having a plurality of unit lenses formed on one surface of the base material layer, each of the unit lenses having a convex shape, wherein a diffusion portion is formed in each of the unit lenses. The amount and cost of the light diffusing agent can be reduced, light transmittance can be improved, light uniformity can be enhanced without occurrence of bright lines, and intensity of light to be viewed is improved, thereby enhancing luminance | 07-02-2009 |
| 20090168421 | BACKLIGHTING ASSEMBLY FOR USE IN SLIM FLAT PANEL DISPLAY AND DISPLAY DEVICE HAVING SAME - A backlight assembly includes a plurality of lamps, a multi-plate diffusion member, optical sheets and a receiving container. The lamps have a rod shape extended in a first direction, and are arranged along a second direction that is substantially perpendicular to the first direction. The diffusion member is disposed above the lamps and has at least two optical plates. Each of the optical plates includes a plurality of optical patterns on a surface facing away from the lamps. The optical patterns are extended in the first direction and aligned along the second direction. The optical sheets are disposed above the diffusion member to improve optical characteristics of passed through light. The receiving container includes a reflective bottom plate and a sidewall formed on an edge of the bottom plate to receive the lamps, the diffusion member and the optical sheets. | 07-02-2009 |
| 20100073909 | BACKLIGHT ASSEMBLY AND DISPLAY DEVICE HAVING THE SAME - A backlight assembly includes; light sources which emit light, a diffusion plate including an incident surface on which the light is incident, an exit surface which is disposed substantially opposite to the incident surface and from which the light exits, and a lens pattern which is disposed on the exit surface, and an optical sheet which overlaps the diffusion plate and includes a prism pattern on a top surface thereof, wherein each lens of the lens pattern includes a first curved portion which forms part of a curve and first linear portions which extend from both ends of the first curved portion, respectively, and each prism of the prism pattern includes a second curved portion at an apex thereof. | 03-25-2010 |
| 20100142188 | BACKLIGHT ASSEMBLY - A backlight assembly includes a plurality of light sources emitting light and a diffusion plate. The diffusion plate includes an incident surface on which the light is incident, an exit surface which is opposite the incident surface and from which the light exits, and first and second lens patterns which are disposed on the exit surface and have different shapes from each other. Each of the first lens patterns includes a first curved portion which forms a curve and first linear portions which extend from both ends of the first curved portion, respectively. Each of the second lens patterns includes a second curved portion which forms a curve and second linear portions which extend from both ends of the second curved portion, respectively. | 06-10-2010 |
