  • Publication number: 20090185103
    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.

  • Patent number: 7478942
    Abstract: A light guide plate includes a light incident surface for receiving light, first and second light emission surfaces for emitting light at a first light emission angle with respect to the first and second light emission surfaces, and a light reflection pattern formed on the first light emission surface, for reflecting the light toward the second light emission surface. The reflected light from the light reflection pattern exits the second light emission surface at a second light emission angle with respect to the second light emission surface, and the second light emission angle is larger than the first light emission angle. The light reflection pattern includes multiple dots each having a prim pattern on their surface and light reflecting surfaces elongated in a selected direction. The adjacent light reflecting surfaces meet each other at their elongated edges to form a prism shape.

  • Publication number: 20090015752
    Abstract: A method for illuminating a liquid crystal display device, a back-light assembly for performing the same and a liquid crystal display device using the same can improve the front luminance and production yield. Lights from a lamp is incident to a LCD panel side, which are then primarily diffused for a uniformity of the luminous flux of the incident lights. The luminous flux of the primarily diffused lights is condensed with respect to a first orientation component on a plane in parallel with the LCD panel, and then partially and secondarily diffused for extending a view angle of pixels of the LCD panel. After the luminous flux of the secondarily diffused lights is condensed with respect to a second orientation component perpendicular to the first orientation on the parallel plane, the condensed lights are illuminated onto the LCD panel.

  • Publication number: 20080212331
    Abstract: In an LCD apparatus having an optical member, the optical member has a base body having a light incident surface and a light emitting surface faced the light incident surface. A first resin layer is formed on the light emitting surface and a light diffusing pattern is uniformly formed on the first resin layer so as to diffuse a first light and emit a second light. Accordingly, the LCD apparatus can improve display quality and can be fabricated in low-cost manufacture. Also, since the light diffusing pattern is formed with a curable material, the light diffusing pattern can have various shapes and superior reproducibility.

  • Publication number: 20080043492
    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.
