Abstract
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.
