    摘要： A backlight assembly that is adapted for use with an image displaying flat panel includes a light guide plate assembly and one or more light sources disposed under the light guide plate assembly. An upper portion of the light guide plate assembly is overlapped by a display area of the flat panel while a lower portion is disposed under the upper portion, and includes light guiding material for redirecting sourced light as well as reflectors for also redirecting light sourced from small, light sourcing areas underneath the upper portion for redistribution into the larger area of light guiding material provided in the upper portion of the light guide plate assembly. The upper portion also has one or more light reflectors. In one embodiment, opposed ones of light sources are angled so they don't shine light directly into one another.

    摘要： An optical member that lends itself to be more cost-effectively manufactured than a conventional optical member is presented. A display device made with the optical member can be thinner than the conventional optical member. The optical member includes a light-incident face that receives light emitted from a lamp positioned at a side of the optical member, a light-exiting face that is in a plane perpendicular to the light-incident face, and a light reflecting face opposite to the light-exiting face. A light-concentrating pattern having a plurality of concentric circles is formed on the light-exiting face. The light-concentrating pattern may be the Fresnel lens pattern. A diffusing pattern for diffusing the light is formed on the light reflecting face. Since patterns are formed on the optical member, additional optical sheet such as a prism sheet, a reflective polarizing sheet, a diffusion sheet, etc., is unnecessary.

    摘要翻译： 本发明提出一种光学元件，它比传统光学元件更经济高效地制造。 由光学构件制成的显示装置可以比传统的光学构件更薄。 光学构件包括光入射面，其接收从位于光学构件侧的灯发出的光，与光入射面垂直的平面中的光出射面和与光入射面相反的光反射面 光出面。 在出射面上形成具有多个同心圆的聚光图案。 光聚集图案可以是菲涅尔透镜图案。 在光反射面上形成用于漫射光的扩散图案。 由于在光学构件上形成图案，所以不需要诸如棱镜片，反射偏振片，扩散片等附加的光学片。

    摘要： A diffusion plate having a multi-layered structure, a backlight assembly having the diffusion plate, and a display device having the diffusion plate are presented. The diffusion plate includes a lower skin layer, a core layer, and an upper skin layer. The lower skin layer modulates and mixes light. The core layer is on the lower skin layer to diffuse the light that has passed through the lower skin layer. The upper skin layer is on the core layer. The upper skin layer has a prism patterned on a surface. Therefore, the number of optical sheets is decreased, and luminance uniformity is improved.

    摘要： A backlight assembly including a container having a light exiting boundary, and a light source part. The container includes a first light source supporting part supporting first and second light sources, and a reflector extending from the first light source supporting part. The reflector reflects the light from the first and second light sources to guide the light to the light exiting boundary. The first light source is disposed under the light exiting boundary and generates the light. The second light source is spaced apart from the first light source in a first direction by a first distance. The first direction is substantially parallel with the light exiting boundary. The second light source is spaced apart from the light exiting boundary in a second direction by a first depth. The second direction is substantially perpendicular to the light exiting boundary.
