    • An edge-lit backlight assembly is provided for backlighting a display. The backlight assembly may include: a light guide having a first segment and a second segment disposed within a common plane; a first light emitting diode disposed along an edge of the first segment of the light guide such that light emitted from the first light emitting diode propagates through the first segment; and a second light emitting diode disposed along an edge of the second segment of the light guide such that light emitted from the second light emitting diode propagates through the second segment. The first segment of the light guide is at least partially optically isolated from the second segment such that light emitted from the first light emitting diode is at least partially blocked from propagating through the second segment.
    • 提供用于背光显示器的边缘照明组件。 背光组件可以包括:光导,其具有设置在公共平面内的第一段和第二段; 沿着所述光导的所述第一部分的边缘设置的第一发光二极管,使得从所述第一发光二极管发出的光传播通过所述第一部分; 以及沿着光导的第二段的边缘设置的第二发光二极管,使得从第二发光二极管发射的光通过第二段传播。 光导的第一段至少部分地与第二段光学隔离,使得从第一发光二极管发射的光至少部分地被阻止不通过第二段传播。
