  • Patent number: 7775701
    Abstract: A backlight assembly includes a light source, a light-guide plate and an integrally formed frame. The light-guide plate guides light generated from the light source. The integrally formed frame includes a chassis and a mold frame integrally combined with the chassis as an indivisible unitary element through insert/outsert injection. The integrally formed frame receives the light source and the light-guide plate. A hemming part is formed on a sidewall of the chassis to increase strength of the integrally formed frame. Therefore, the number of elements is decreased, and strength against bending stress, impact resistance and heat dissipation are improved.

  • Publication number: 20090161036
    Abstract: In a method of manufacturing a backlight assembly, a light reflective and heat-radiating sheet including a light reflective sheet layer to reflect light and a heat-radiating sheet layer are prepared. The heat-radiating sheet layer includes a coupling layer integrally formed with a surface of the light reflective sheet layer and heat-diffusing particles are dispersed in the coupling layer to diffuse heat provided from the exterior. The light reflective and heat-radiating sheet is disposed so that the coupling layer is adhered to a bottom plate of a receiving container. Thus, impurities may be prevented and/or reduced, and assembling efficiency may be improved.
