    • A scanning backlight for a stereoscopic 3D liquid crystal display apparatus includes a light guide formed from a plurality of segments. Each segment has a first side and a second side opposite the first side, and a first surface extending between the first and second sides and a second surface opposite the first surface. The first surface substantially re-directs light and the second surface substantially transmits light. The plurality of segments are arranged substantially in parallel and with the second surfaces transmitting light in substantially the same direction to provide backlighting for a stereoscopic 3D liquid crystal display. A first light source is disposed along the first side of each segment for transmitting light into the light guide from the first side, and a second light source is disposed along the second side of each segment for transmitting light into the light guide from the second side. Each segment first and second light source is selectively turned on and off in a particular pattern and each segment light source selectively transmits light into the light guide first side or light guide second side to form a scanning backlight.
    • 立体3D液晶显示装置的扫描背光源包括由多个片段形成的导光体。 每个段具有与第一侧相对的第一侧和第二侧,以及在第一和第二侧之间延伸的第一表面和与第一表面相对的第二表面。 第一表面基本上重新引导光并且第二表面基本上透射光。 多个片段基本上平行布置,并且第二表面沿基本上相同的方向透射光以为立体3D液晶显示器提供背光。 第一光源沿着每个段的第一侧布置,用于将光从第一侧透射到光导中,并且第二光源沿着每个段的第二侧设置,用于将光从第二侧透射到光导中 。 每个段第一和第二光源被选择性地以特定图案打开和关闭,并且每个段光源选择性地将光传输到光导第一侧或光导二次侧以形成扫描背光。
