Abstract:
A backlight assembly includes a light emitting unit, a reflective sheet, and a bottom cover. The light-emitting unit includes a light source emitting light and an optical system. The optical system is spaced apart from the light source in a direction in which the light emitted from the light emitting unit initially travels. The optical system has a curved shape that reflects a portion of the light emitted from the light source and transmits a remaining portion of the light emitted from the light source. The reflective sheet is disposed under the light-emitting unit to re-reflect the light reflected by the optical system. The bottom cover accommodates the light emitting unit and the reflective sheet. Thus, the light-spreading angle of the light-emitting unit becomes wide.
Abstract:
A backlight unit includes a light source part configured to emit a light and a reflective sheet disposed under the light source part. The light source part includes a first light source block including a plurality of light sources with first distances therebetween and a second light source block including a plurality of light sources with second distances therebetween. The first distances increase or decrease as the light sources of the first light source block are closer to an end portion of the first light source block than to a center portion of the first light source block, and the second distances increase as the light sources of the second light source block axe closer to an end portion of the second light source block than to a center portion of the second light source block.
Abstract:
A display device includes a pixel circuit, a first insulation layer covering the pixel circuit, a first electrode disposed on the first insulation layer, a second electrode disposed on the first insulation layer while being spaced apart from the first electrode, a second insulation layer covering the first electrode, the second electrode, and the first insulation layer disposed between the first electrode and the second electrode, and a light emitting element electrically connected to the first electrode and the second electrode on the second insulation layer and disposed between the first electrode and the second electrode. Here, the second insulation layer includes a first area overlapping the first electrode, a second area overlapping the second electrode, and a stopper area disposed between the first electrode and the second electrode, and the stopper area has a thickness different from that of each of the first area and the second area.
Abstract:
A backlight unit includes a light source which generates light, a light guide plate which guides the light substantially in an upward direction, a first frame member which holds the light source and diffuses the light traveling substantially in the upward direction between the light source and the light guide plate, a second frame member which holds the light guide plate, a third frame member which holds the light guide plate, a reflective plate disposed under the light guide plate and which reflect the light leaked downwardly from the light guide plate substantially to the upward direction, and an optical sheet disposed on the light guide plate and the first to third frame members and which diffuses the light provided from the first frame member and the light guide plate and condenses the light substantially in the upward direction.
Abstract:
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.
