The backlight unit includes a display housing, a light source which is arranged along an inner circumference the display housing, a light guide plate through which light of the light source is transmitted, and which forms surface light, an optical sheet which is disposed on an upper side of the light guide plate to upwardly diffuse the light of the light source transmitted through the light guide plate, a plurality of first fixing units, each of which fix both the light guide plate and the optical sheet, a plurality of second fixing units which support only the light guide plate, and a support frame which is connected to the display housing to fix the optical sheet to the display housing provisionally, and has a window formed on a surface corresponding to the light guide plate to allow light to pass therethrough. | 11-25-2010 |
20120162281 | LIGHT GUIDE PLATE, BACKLIGHT UNIT AND DISPLAY APPARATUS INCLUDING THE SAME AND MANUFACTURING METHOD THEREOF - A light guide plate, a backlight unit and a display apparatus including the same and a manufacturing method thereof are provided. The light guide plate includes: a body which includes an incident surface and an emission surface; at least one first optical path converter which is formed in an opposite surface of the body which is opposite to the emission surface, and extends continuously in a first direction to convert an optical path of an incident light introduced through the incident surface so that the incident light passes through the emission surface; and at least one second optical path converter which is formed in the opposite surface, and is arranged discontinuously in at least one row extending in the first direction. | 06-28-2012 |
20120182500 | SCANNING BACKLIGHT UNIT AND LIQUID CRYSTAL DISPLAY HAVING THE SAME - A scanning backlight unit, a liquid crystal display and television and a television are provided herein. The backlight unit including a light source unit having plural groups of light sources which emit light in a main incidence direction; a control unit which controls the plural groups of light sources; and a light guiding plate having a bottom surface formed with a dispersion pattern dispersing the light received from the light source unit, wherein the dispersion pattern includes a plurality of grooves, with a groove of the plurality of grooves having a shape with a first size parallel to the main incidence direction and a second size perpendicular to the main incidence direction, and wherein the first size is larger than the second size. | 07-19-2012 |
20130107574 | BACKLIGHT UNIT AND DISPLAY APPARATUS HAVING THE SAME | 05-02-2013 |
20130114300 | BACKLIGHT UNIT AND DISPLAY APPARATUS HAVING THE SAME - A backlight unit of a display apparatus, the backlight unit includes a light source unit disposed on at least one edge of a display panel; and a light guide plate disposed at rear of the display panel. The light guide plate includes a first pattern part including a plurality of first pattern lines formed on a lower surface of the light guide plate, and which extend perpendicularly to a transmission direction of the radiated light, and which totally reflect the radiated light to an upper surface of the light guide plate, and a second pattern part including a plurality of second pattern lines formed on the upper surface of the light guide plate, and which extend parallel with the transmission direction of the radiated light, and which guide light transmitted in the light guide plate to travel and exit along the second pattern lines. | 05-09-2013 |
20130242612 | LIGHT GUIDE PANEL AND BACKLIGHT UNIT HAVING THE SAME - A light guide panel (LGP) is provided, which includes a front surface, a rear surface, and four edge surfaces, in which rays of light emitted from light sources are introduced through at least one of the four edge surfaces, a plurality of lenticular patterns formed on one of the front surface and the rear surface, and a plurality of light emitting patterns which induce the rays of light emitted from the light sources toward the front surface. The plurality of light emitting patterns are integrally formed with the plurality of lenticular patterns. | 09-19-2013 |
20140211121 | DISPLAY MODULE AND DISPLAY APPARATUS HAVING THE SAME - A display module includes a display panel; a backlight unit which is disposed behind the display panel and configured to emit light toward the display panel; a bottom chassis configured to accommodate the backlight unit; and a reflective sheet which is disposed inside the bottom chassis and configured to reflect a light portion incident thereon toward the display panel. The reflective sheet includes a sheet bottom portion corresponding to a front surface of the bottom chassis, a sheet inclined portion which is obliquely formed to face a rear surface of the display panel, and a light adjustment portion which is provided on the sheet inclined portion and configured to adjust the light portion reflected by the sheet inclined portion. | 07-31-2014 |
20140211123 | DISPLAY MODULE AND DISPLAY APPARATUS HAVING THE SAME - A display module includes a display panel, a diffusion plate, a bottom chassis, and a transparent spacer made having a diffusion pattern formed thereon disposed on the bottom chassis to support the diffusion plate. | 07-31-2014 |
20140333873 | DISPLAY DEVICE - A display device including a display panel configured to display, a backlight unit configured to emit light toward the display panel, a pattern layer having a pattern formed to compensate for short-wavelength light among light emitted the backlight unit, and a diffusion plate configured to diffuse the compensated short-wavelength light and the light emitted from the backlight unit, so that the non-uniform color generated due to the color breakup is improved by use of blue ink having a bead shape that is disposed on the diffusion plate. | 11-13-2014 |
