20110013119 | BACKLIGHT ASSEMBLY AND DISPLAY APPARATUS HAVING THE SAME - A backlight assembly includes a light source generating light and a first optical member diffusing the light. The first optical member includes a first diffusion member provided on an exit surface of the first optical member, from which the light exits, to diffuse the light. The first diffusion member includes a plurality of edges each having a curved shape and extending between the exit surface and a vertex of the first diffusion member. Accordingly, the light exiting through the exit surface is effectively diffused by the edges of the first diffusion member. | 01-20-2011 |
20110292639 | BACKLIGHT UNIT AND DISPLAY APPARATUS HAVING THE SAME - A display apparatus includes a display panel, a plurality of spaced apart point light sources outputting light and each having an orientation angle greater than or equal to about 50° and less than about 90°, and an optical plate interposed between the display panel and the point light sources. The optical plate has a base comprising front and rear surfaces and a plurality of convex sections formed on the front surface of the base. Each convex section has a cross section perpendicular to the front surface in which the cross section has a form of a segment of an ellipse including an arc of an ellipse and a chord linking both ends of the arc while satisfying an equation, | 12-01-2011 |
20120139964 | DISPLAY PANEL MODULE AND MULTI-PANEL DISPLAY APPARATUS INCLUDING THE SAME - A display panel module includes a display panel, a lens sheet, and an upper polarizing plate. The display panel includes a display region in which an image is displayed, and a non-display region in which the image is not displayed. The lens sheet faces a light emitting surface of the display panel and changes a path of a portion of light emitted from the display region of the display panel, to transmit the portion of the light onto the non-display region of the display panel. The upper polarizing plate faces a light exiting surface of the lens sheet, and transmits only light traveling parallel to a polarizing axis | 06-07-2012 |
20120201050 | BACKLIGHT UNIT AND DISPLAY APPARATUS HAVING THE SAME - A display apparatus includes a light guide plate, a light source unit and a display panel. The light guide plate includes an incident surface, an exit surface and an opposite surface opposite to the exit surface and guides a light incident into the incident surface toward the exit surface. The light source unit includes a light source which generates light and is disposed adjacent to the incident and has an emitting surface inclined with respect to the incident surface. An extension line of a normal line of the emitting surface passes through the opposite surface, and the light is incident into the incident surface while being inclined toward the opposite surface. The display panel displays an image by receiving the light emitted from the exit surface. | 08-09-2012 |
20120236592 | DISPLAY APPARATUS INCLUDING LIGHT GUIDE PLATE COUPLING MEMBER - Provided is a display apparatus, which includes a light source unit providing light, a light guide panel guiding the light to a display panel, the display panel receiving the light to display an image, and a bottom chassis accommodating the light guide panel, the light source unit, and the display panel. The light guide panel is adjacent to the light source unit, and includes a light incident surface to which the light is incident, a light output surface from which the light is emitted, and an opposite surface opposed to the light output surface. The display panel faces the light output surface and receives the light to display an image. The bottom chassis has a bottom facing the opposite surface. The light guide panel includes a coupling member protruding from the opposite surface and coupled to the bottom chassis. | 09-20-2012 |
20130314899 | DISPLAY DEVICE - A display device includes first light emitting devices arranged in a line in a protective member, second light emitting devices parallel to and alternately arranged with the first light emitting devices, and optical member supporters in the protective member between the first and second light emitting devices. Each optical member supporter is positioned at a center of a parallelogram defined by two adjacent first light emitting devices and two adjacent second light emitting devices, and each transparent optical member supporter includes a first surface that faces one of the first light emitting devices and a second surface opposite the first surface that faces one of the second light emitting devices. Each optical member supporter includes a plate portion having the first and second surfaces, and a hook portion that extends through the protective member. A width of the plate portion decreases with increasing distance from the hook portion. | 11-28-2013 |
20140009913 | BACKLIGHT ASSEMBLY AND DISPLAY APPARATUS HAVING THE SAME - A backlight assembly includes a light source generating light and a first optical member diffusing the light. The first optical member includes a first diffusion member provided on an exit surface of the first optical member, from which the light exits, to diffuse the light. The first diffusion member includes a plurality of edges each having a curved shape and extending between the exit surface and a vertex of the first diffusion member. Accordingly, the light exiting through the exit surface is effectively diffused by the edges of the first diffusion member. | 01-09-2014 |
20140036542 | BACKLIGHT UNIT AND DISPLAY APPARATUS HAVING THE SAME - A display apparatus includes a light guide plate, a light source unit and a display panel. The light guide plate includes an incident surface, an exit surface and an opposite surface opposite to the exit surface and guides a light incident into the incident surface toward the exit surface. The light source unit includes a light source which generates light and is disposed adjacent to the incident and has an emitting surface inclined with respect to the incident surface. An extension line of a normal line of the emitting surface passes through the opposite surface, and the light is incident into the incident surface while being inclined toward the opposite surface.
