Abstract: A backlight unit and an LCD employing the backlight unit are provided. The backlight unit includes: a base substrate; a plurality of point light sources arranged in two or more lines on the base substrate; a diffusion plate disposed over the plurality of point light sources to diffuse and transmit incident light; and at least one barrier rib forming two or more division areas by being disposed between the base substrate and the diffusion plate to be upright with respect to the base substrate between the lines and having a wall surface reflecting light incident from the plurality of point light sources, at least a portion of an end portion of the barrier rib being inserted into the diffusion plate.

Abstract: A backlight unit for a dynamic image and a display employing the same are provided. The backlight unit is used for a light source of a display and includes light-emitting devices located separately on a substrate, an image analyzer which analyzes an image signal and extracts position information on a region requiring the relative increase or decrease of brightness, and a control unit which independently drives and controls the light-emitting devices located in a region corresponding to the position information inputted from the image board. Accordingly, the display employing the backlight unit can provide a more dynamic and realistic image.

Abstract: A direct light type backlight unit having a structure in which divided luminance areas are sequentially turned on and off and a liquid crystal display device employing the backlight unit are provided. The backlight unit includes: a base substrate; a plurality of point light sources arranged in a plurality of lines and mounted on the base substrate; and a reflector sheet vertically formed between lines of the point light sources, reflecting light emitted from the point light sources.

Abstract: A light emitting assembly, a backlight unit, and a display are provided. The light emitting assembly includes: light emitting modules, wherein the light emitting modules include: a substrate having an electrical connecting portion; and a plurality of light emitting units arranged on the substrate, and wherein the light emitting modules can be assembled using the electrical connecting portion. The light emitting assembly can be assembled using the light emitting modules comprised of independent blocks and thus, can be freely used regardless of the size of the display.

Abstract: A light emitting panel, a backlight system having the same, and a liquid crystal display (LCD) device having the backlight system. The light emitting panel includes: a bottom surface from which incident light is reflected; at least one protrusion that has a side surface and protrudes from the bottom surface; and a plurality of light emitting diodes (LEDs) that are installed in a row in a lengthwise direction on the side surface of the protrusion and obliquely angled with respect to the bottom surface.

Abstract: A multi-chip light emitting diode unit, and a backlight unit and a liquid crystal display device employing the same, are provided. The multi-chip light emitting diode unit includes: a base; a plurality of light emitting elements which are arranged on the base and irradiate at least two wavelengths of light; and a cap which is provided at an upper side of each of the plurality of the light emitting elements, made of a material having a greater refractive index than an adjacent external medium, and which totally internally reflects the light emitted from the light emitting elements.

Abstract: A backlight system and an LCD employing the backlight system. The backlight system includes a plurality of light emitting devices arranged on a base plate to form a plurality of lines each including a plurality of light emitting devices, and a light guide panel having a sidewall spaced apart from the plurality of light emitting devices such that light incident from the plurality of light emitting devices is dispersed by inner reflection, and a scattering region formed adjacent to the base plate such that light incident into the scattering region is irregularly reflected to emit in a direction away from the base plate.

Abstract: A backlight unit and an LCD apparatus employing the same. The backlight unit includes: a base plate, a plurality of light emitting units arranged on the base plate to form at least one line, an optical plate disposed above the plurality of light emitting units, and a light transmission diffusion plate disposed on the optical plate to diffuse and transmit incident light. The optical plate includes: a plurality of reflection mirrors formed at a lower surface thereof to face the plurality of light emitting units to reflect light directly emitted upward from the plurality of light emitting device units, and a saw-tooth reflection/refraction pattern formed at an upper surface thereof to spread incident light at a wide angle.

Abstract: A backlight unit including a plurality of light-emitting device units with varying arrangement intervals such that the light-emitting device units are more densely arranged at edges of a base plate than at center thereof, and a liquid crystal display (LCD) apparatus employing the same. The backlight unit is designed to prevent creation of dark portions on corners due to a shortage in an amount of light, thereby providing improved brightness uniformity.
