    摘要： A light guiding unit that is capable of reducing the thickness of a backlight assembly and operating with fewer light sources is presented. The light guiding unit includes a first surface, a second surface and a light incident surface. The first surface includes a light exiting surface and an upper guiding curved surface that is recessed with respect to the light exiting surface. The second surface includes an opposite surface that is substantially parallel to the light exiting surface and a lower guiding curved surface recessed on the opposite surface toward the first surface, the lower guiding curved surface being positioned along the upper guiding curved surface. The light incident surface is formed on an end portion of the lower guiding curved surface.

    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 backlight assembly includes at least one light-generating board, a light source driving board and a coupling board. The light-generating board generates light. The light source driving board provides control signals to the light-generating board. The coupling board is coupled via slot connectors to the light-generating board and the light source driving board to electrically connect the light-generating board and the light source driving board to each other. Thus, manufacturing efficiency may be improved in comparison with electrically connecting the light-generating board and the light source driving board through wires.

    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 that improves color uniformity is presented. The backlight assembly includes a plurality of point light sources, an optical member on the point light sources, and a reflecting plate that is positioned to receive light that is reflected by the optical member. The point light sources includes a red light emitting diode generating red light, a green light emitting diode generating green light, and a blue light emitting diode generating blue light. The optical member transmits white light formed by mixing at least some of the red, green and blue lights and reflects the untransmitted portion of the red, green and blue lights. The reflecting plate, which receives the reflected light from the optical member, includes a plurality of patterns that reflect the incident red, green and blue lights, essentially “recycling” the light that did not get transmitted in the first pass.
