  • Publication number: 20070035223
    Abstract: A backlight assembly includes a receiving container, a flat fluorescent lamp and a heat generating sheet. The flat fluorescent lamp is received in the receiving container. The flat fluorescent lamp includes a plurality of discharge spaces to generate light. The heat generating sheet is positioned adjacent to the flat fluorescent lamp, for example, under the flat fluorescent lamp, to supply the flat fluorescent lamp with heat. The heat generating sheet corresponds to an effective light emitting region of the flat fluorescent lamp where the light is emitted. As a result, heat is provided to the flat fluorescent lamp, thereby decreasing a time for stabilizing a luminance and improving light emitting characteristics.

  • Publication number: 20070035245
    Abstract: A flat-type fluorescent lamp includes a first substrate, a second substrate and an adhesive member. The second substrate corresponds to the first substrate to form a plurality of discharge spaces. The adhesive member is interposed between the first and second substrates to combine the first substrate with the second substrate. The adhesive member includes a protrusion protruding in a longitudinal direction of the discharge spaces. Therefore, luminance uniformity and image display quality are improved.

  • Publication number: 20060171140
    Abstract: A backlight assembly includes a surface light source device, an optical member, a supporting member and a receiving container. The surface light source device includes a first substrate and a second substrate facing the first substrate to form a light-emitting region and a non-emitting region. The surface light source device generates light. The optical member enhances optical properties of the light generated by the surface light source device. The supporting member is disposed at the non-emitting region of the surface light source device to support the optical member. The receiving container receives the surface light source device and the optical member. Advantageously, sagging of the optical member is reduced, or effectively prevented, to enhance display quality.

  • Publication number: 20060139959
    Abstract: In a backlight assembly that provides improved luminance uniformity and a LCD device having the same, the backlight assembly includes a flat fluorescent lamp and a receiving container. The receiving container has a bottom plate and sidewalls to receive the surface light source. The bottom plate includes openings that overlap the outermost lateral discharge spaces located along the edges of the flat fluorescent lamp. The openings are formed at corner portions of the bottom plate and extend parallel to the discharge spaces of the lamp. The backlight assembly further includes a buffer member interposed between the flat fluorescent lamp and the receiving container to support the flat fluorescent lamp. The buffer member includes protrusions couplable to holes of the receiving container, allowing the buffer member to be firmly secured to the receiving container. The device decreases current leakage of the surface light source, thus improving luminance uniformity.
