  • Publication number: 20060291240
    Abstract: A backlight assembly supplies a guided light to a display panel having a main display part on which a main image is selectively displayed, and a sub display part on which a sub image is constantly displayed. The backlight assembly includes a light source and a light guiding unit. The light source generates a light. The light guiding unit includes a light incident surface, a light exiting surface, and a corresponding surface. The light from the light source is incident into the light incident surface. The light exiting surface has a main region and a sub region, the sub region having an optical pattern increasing a luminance of the light. The guided light exits the light exiting surface. The corresponding surface corresponds to the light exiting surface. A luminance uniformity and a luminance when viewed on a plane are increased.

  • Patent number: 7126651
    Abstract: Disclosed is a liquid crystal display apparatus in which a liquid crystal display module and cases are tightly combined. At least one protuberance formed on a top chassis of the liquid crystal display module combines at least one fixing portion formed on a portion of a rear case corresponding to the at least one protuberance. Also, a fixing protuberance formed on a portion of a front case is inserted into between the liquid crystal display module and the rear case, thereby preventing the liquid crystal display module from being moved. Therefore, the liquid crystal display module and the cases are tightly combined, and productivity of the liquid crystal display apparatus can increase by reducing the number of parts demanded for fabrication of the liquid crystal display module and the cases.

  • Publication number: 20060114692
    Abstract: In a two-way backlight assembly and a two-way LCD apparatus, the two-way backlight assembly provides light emitted from one light source to a first direction where a main LCD panel is placed and to a second direction where a sub LCD panel is placed. Also, a sub mold part for receiving the sub LCD panel comprises a black-colored material so as to prevent reflection of the light. Accordingly, thickness and power consumption of the backlight assembly may be reduced and display quality may be also improved by preventing leakage of the light at ends of the sub LCD panel.

  • Publication number: 20050002172
    Abstract: A diffusively reflective film includes a base film, a light reflection layer and a light diffusion layer. The base film is flexible. The light reflection layer is disposed on the base film. The light reflection film reflects a first light. The light diffusion layer is disposed on the light reflection layer. The light diffusion layer diffuses the first light to form a second light. The diffusively reflective film may be bent to cover the light guide plate without being broken so as to increase the amount of light. Thus, a display quality is enhanced. Further, the diffusively reflective film covers the first side face, the second side face and the first face of light guide plate at once. Thus, productivity is enhanced and its manufacturing cost is reduced.
