摘要： A backlight assembly includes a light-generating unit, a heat-radiation member, a first receiving container, and a second receiving container. The heat-radiation member is disposed under the light-generating unit and radiates heat generated by the light-generating unit. The first receiving container is composed of a bottom portion and side portion extended from the bottom portion. The first receiving container has an opening formed through partial removal of the bottom portion so that the heat-radiation member received inside is exposed. The second receiving container is disposed under the first receiving container. An air layer is formed in between the first and second receiving containers.

摘要： A backlight assembly includes a light-generating device, a receiving container, a first heat-dissipating member, a heat-blocking member, and a second heat-dissipating member. The receiving container receives the light-generating device. The first heat-dissipating member contacts the receiving container. The heat-blocking member is disposed on the first heat-dissipating member. The second heat-dissipating member contacts the first heat-dissipating member. Therefore, liquid crystal is prevented from being deteriorated by heat generated by a light source.

摘要： A light-generating device includes a driving substrate and a plurality of light source arrays. The driving substrate has a rectangular planar shape. The plurality of light source arrays is formed on the driving substrate. The light source arrays include at least one light emitting diode to generate light in response to power being applied through the substrate, and the light source arrays are spaced apart from each other. Thus, heat generated from the light-generating device is rapidly dissipated from the light-generating device, improving brightness of the light, brightness uniformity of the light and color reproducibility of the light.

摘要： A backlight for a display device includes a board, a plurality of light emitting diodes (LEDs) mounted on the board, and a light guiding plate that is provided on the LEDs and has light reflecting grooves formed directly on respective LEDs. The light reflecting grooves are formed at an upper surface of the light guiding plate, having a shape of a reversed cone. In this backlight, the light traveling directly upward from the LED is efficiently reflected by total internal reflection and then recycled, resulting in a uniform light distribution of the backlight.
