    • A scanning backlight for a stereoscopic 3D liquid crystal display apparatus includes a light guide having a first side and a second side opposite the first side, and having 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. A plurality of first light sources are arranged along the first side of the light guide for transmitting light into the light guide from the first side and a plurality of second light sources are arranged along the second side of the light guide for transmitting light into the light guide from the second side. The first light sources are divided into a plurality of first groups and the second light sources are divided into a plurality of second groups, each first group having a corresponding and opposing second group, and the first groups and second groups are selectively turned on and off in a particular pattern where only the first group or corresponding and opposing second group selectively transmits light into light guide at one time.
    • 用于立体3D液晶显示装置的扫描背光源包括具有第一侧和与第一侧相对的第二侧的光导,并且具有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。 多个第一光源沿着光导的第一侧布置,用于将光从第一侧传输到光导中,并且沿着光导的第二侧布置多个第二光源,用于将光透射到光 指导从第二边。 第一光源被分成多个第一组,第二光源被分成多个第二组,每个第一组具有对应的和相对的第二组,并且第一组和第二组选择性地打开和关闭 在其中只有第一组或相应和相对的第二组一次选择性地将光透射入光导的特定图案中。
