20080310184 | METHOD OF MANUFACTURING LIGHT GUIDE PLATE, LIGHT GUIDE PLATE, BACKLIGHT UNIT WITH THE LIGHT GUIDE PLATE AND DISPLAY APPARATUS HAVING THE SAME - A method of producing an edge-light type light guide plate having a light exiting surface and a light reflecting surface having light reflective dots formed thereon in a scattered fashion. The method includes (a) producing a first prototype of the light guide plate having primary dots formed on the light reflecting surface, (b) examining optical characteristics of the first prototype relating to light exiting from the light exiting surface thereof, and (c) producing a second prototype of the lightguide plate when the examined first prototype exhibits unsatisfactory optical characteristics. The second prototype has primary dots that are the same as the primary dots of the first prototype in size and distribution, and secondary dots arranged between the primary dots in at least part of the light reflecting surface. The steps (b) and (c) are repeated until a prototype is produced which exhibits satisfactory optical characteristics. | 12-18-2008 |
20090027918 | TRANSREFLECTORS, TRANSREFLECTOR SYSTEMS AND DISPLAYS AND METHODS OF MAKING TRANSREFLECTORS - Light emitting assembly includes at least one film, sheet, plate or substrate positioned between a light source and a display for redirecting at least some of the light emitted by the light source. One side of the film, sheet, plate or substrate may have a pattern of reflective or refractive surfaces or deformities and the other side may have corresponding or aligned optical deformities of well defined shape. Light emitted from the light source that strikes a reflective or refractive surface or deformity on the one side of the film, sheet, plate or substrate passes through the film, sheet, plate or substrate and is redirected by at least one corresponding optical deformity on the other side of the film, sheet, plate or substrate. | 01-29-2009 |
20090129114 | Domestic Appliance, in Particular Fitted Domestic Appliance With a Controllable Operating Display - A domestic appliance includes an operation indicator having an illumination element for emitting a light beam by means of which a gap between the domestic appliance and a surface adjacent to the domestic appliance can be illuminated, and a reflection element in the gap for directing or bundling light emitted by the illumination element. | 05-21-2009 |
20120127749 | SIDE-LIGHT TYPE BACKLIGHT MODULE WITH LOCAL HEAT-DISSIPATION ENHANCEMENT - The present invention discloses a side-light type backlight module with local heat-dissipation enhancement. The backlight module is provided with a local heat-dissipation enhancement region on a portion of the back plate close to at least one light input side edge, and a surface of the local heat-dissipation enhancement region has a thermal-conductivity enhancement coating and a three-dimensional heat-dissipation profile, so that the temperature can be rapidly distributed to an even degree and lowered down, and the heat exchange area can be increased. Thus, the side-light type backlight module with local heat-dissipation enhancement of the present invention can efficiently prevent from affecting the chromaticity and brightness of a light emitting device due to the high temperature, so as to improve the uniformity of the chromaticity and brightness of an entire liquid crystal display (LCD) module and enhance the light extraction efficiency thereof. | 05-24-2012 |
20120250347 | BACKLIGHT ASSEMBLY, METHOD OF MANUFACTURING THE SAME AND DISPLAY APPARATUS HAVING THE SAME - A backlight assembly includes a light source part, a base substrate, an insulation layer, and a reflection layer. The base substrate includes a light incident surface into which the light from the light source part is incident, and a light exiting surface adjacent to the light incident surface and through which the light exits. The insulation layer is formed on the light exiting surface of the base substrate. The reflection layer is formed on the insulation layer and forms a concave pattern along with the base substrate and the insulation layer and has an opening portion through which the light exiting from the light exiting surface passes. | 10-04-2012 |
20130121016 | OPTICAL FILM HAVING IMPROVED OPTICAL PERFORMANCE, AND BACKLIGHT UNIT COMPRISING THE SAME - The present invention relates to an optical film having improved optical performance and to a backlight unit comprising the same. More particularly, the present invention relates to a microlens array (MLA) sheet which comprises a base unit and a lens unit formed on one side of the base unit, wherein the lens unit consists of a plurality of conical lenses. Existing hemispherical microlens array sheets have limitations in terms of improving luminance, and therefore cannot replace prism sheets in high luminance products. However, the microlens array sheet consisting of conical lenses of the present invention can improve both luminance and viewing angle characteristics. | 05-16-2013 |
20140098562 | LIGHTING AND/OR SIGNALING MODULE FOR A VEHICLE COMPRISING A LIGHT GUIDE WITH A RIB AND A SUPPORT WITH MEANS OF ATTACHMENT COLLABORATING WITH THE RIB - The invention relates to a lighting and/or signaling module comprising a support, a light guide arranged in an enclosure of said support and a mask arranged on the support and extending in front of the light guide. The light guide comprises a longitudinal rib intended to collaborate by engaging with a series of hooks belonging to the support. The mask is intended to mask the mounting zones of the light guide. It comprises one or more windows intended to let through the rays of light emitted transversally by the light guide. The rib extends continuously over essentially the entire length of each of the windows. The rib allows simple, rapid and reliable attachment of the light guide to its support. The continuity of the rib among each of the windows means that the creation of any visible non-uniformity through said windows is avoided. | 04-10-2014 |
