20080319715 | LIGHT GUIDE PLATE, METHOD OF MANUFACTURING THE SAME, AND LIQUID CRYSTAL DISPLAY DEVICE INCLUDING THE SAME - A light guide plate includes a light incident surface to which light is incident as incident light, an opposite surface formed opposite to the light incident surface, a light emitting surface through which the incident light is emitted, a rear surface formed opposite to the light emitting surface and including a prism pattern which reflects the incident light to the light emitting surface, and lateral surfaces, wherein a diffuse reflection pattern is formed on at least any one of the light emitting surface and the lateral surfaces to diffuse-reflect light incident to the lateral surfaces, thus rendering a brightness at both the opposite surface and the light incident surface substantially uniform. | 12-25-2008 |
20090185109 | LIQUID CRYSTAL DISPLAY - A liquid crystal display capable of improving display quality while achieving a reduction in manufacturing cost. The liquid crystal display includes a liquid crystal panel having multiple pixels arranged at a first pitch; a light source for supplying light to the liquid crystal panel; and a light guide plate for guiding the light to the liquid crystal panel, wherein prisms are formed on the light guide plate at a second pitch, the second pitch is the sum of a quotient and a corrected value, the quotient is obtained by dividing the first pitch by a natural number m, the corrected value depends on a selected viewing distance and an interval between the liquid crystal panel and the prisms. | 07-23-2009 |
20090213576 | OPTICAL MEMBER, BACKLIGHT ASSEMBLY AND DISPLAY APPARATUS HAVING THE SAME - An optical member according to one or more embodiments includes an optical plate and an optical film. In an embodiment, the optical plate includes an incident part receiving light provided from the exterior and an emitting part emitting the light. The optical film is attached to the incident part and includes a first conductive layer, a second conductive layer facing the first conductive layer and polarized particles disposed between the first conductive layer and the second conductive layer. Thus, light sources of a backlight assembly may be individually driven regardless of the type of light source and the disposition of the light sources, and image display quality may be improved by improving a contrast ratio by realizing various gradation voltages. | 08-27-2009 |
20090290097 | BACKLIGHT ASSEMBLY AND DISPLAY DEVICE HAVING THE SAME - A backlight assembly includes; a plurality of light guide blocks disposed substantially in parallel with each other along a first direction, each of the plurality of light guide blocks including; a light guide plate (“LGP”) having a wedge-shape decreasing in thickness from a first side thereof to a second side thereof, and a light source unit disposed facing a side surface of the LGP, and a light source driving unit which individually controls the light source units of the plurality of light guide blocks to emit light via a local dimming method. | 11-26-2009 |
20100110337 | BACKLIGHT ASSEMBLY AND LIQUID CRYSTAL DISPLAY HAVING THE SAME - A backlight assembly including direct-type lamps and an edge-type lamp and a liquid crystal display having the backlight assembly. The direct-type lamps are arranged with a predetermined interval to emit light, and the edge-type lamp is provided at a side portion of a light guide plate provided above or below the direct-type lamps. The light guide plate and a light guide pattern output light, which is emitted from the edge-type lamp, through a space between two adjacent direct-type lamps. The backlight assembly supplies light to the light receiving region such that brightness is uniformly distributed throughout the light receiving region regardless of the position of the direct-type lamps. | 05-06-2010 |
20100149788 | DISPLAY APPARATUS - A display apparatus includes a display panel, a light source and a plurality of a light guiding plate. The LGP includes light incident, counter, light emitting and rear surfaces. The counter and rear surfaces are respectively opposite to the light incident and light emitting surfaces. The light emitting surface includes an ineffective light emitting area making contact with the light incident surface and an effective light emitting area connecting the ineffective light emitting area with the counter surface. The counter surface of a first light guiding plate is disposed overlapping the light incident surface of a second light guiding plate along a first direction, so that the rear surface partially overlaps with the effective light emitting area of the second light guiding plate, and the light guiding plates collectively form a light guiding plate array along the first direction. | 06-17-2010 |
20100277951 | LIGHT GUIDE PLATE, METHOD OF MANUFACTURING THE SAME, AND LIQUID CRYSTAL DISPLAY DEVICE INCLUDING THE SAME - A light guide plate includes a light incident surface to which light is incident as incident light, an opposite surface formed opposite to the light incident surface, a light emitting surface through which the incident light is emitted, a rear surface formed opposite to the light emitting surface and including a prism pattern which reflects the incident light to the light emitting surface, and lateral surfaces, wherein a diffuse reflection pattern is formed on at least any one of the light emitting surface and the lateral surfaces to diffuse-reflect light incident to the lateral surfaces, thus rendering a brightness at both the opposite surface and the light incident surface substantially uniform. | 11-04-2010 |
20110157913 | LIGHT GUIDE PLATE, DISPLAY APPARATUS HAVING THE SAME, AND METHOD OF MANUFACTURING THE SAME - A light guide plate includes an incident surface receiving incident light from a light source, an exit section that outputs exit light having a light distribution different from a light distribution of the incident light and a reflective section opposite to the exit section. A plurality of first patterns are formed on the exit section while being arranged in a first direction of the exit section to distribute the exit light with maximum brightness in a direction perpendicular to the exit section. A plurality of second patterns are formed on the reflective section to scatter the incident light. | 06-30-2011 |
20120206670 | BACKLIGHT ASSEMBLY AND DISPLAY DEVICE HAVING THE SAME - A backlight assembly includes; a plurality of light guide blocks disposed substantially in parallel with each other along a first direction, each of the plurality of light guide blocks including; a light guide plate (“LGP”) having a wedge-shape decreasing in thickness from a first side thereof to a second side thereof, and a light source unit disposed facing a side surface of the LGP, and a light source driving unit which individually controls the light source units of the plurality of light guide blocks to emit light via a local dimming method. | 08-16-2012 |
