    Abstract: Time-multiplexed backlighting includes a time-multiplexed light source to provide a light beam having a first non-zero propagation angle during a first time interval and a second non-zero propagation angle during a second time interval. A time-multiplexed backlight includes a light guide configured to guide the light beam and a diffraction grating configured to coupled out a portion of the guided light beam with a different principal angular direction in each of the first time interval and the second time interval. A multiview display includes the time-multiplexed light source and a multibeam backlight to provide coupled-out light beams during each of the first and second time intervals, wherein the principal angular directions of the coupled-out light beams correspond to different view directions of the multiview display.

The present disclosure suggests a thin film type back light unit comprising: a light guide film (LGF), a light radiator (VHOE), a first light source (LS1) and a light collimator (WLC). The light guide film (LGF) includes a light entering part (LIN) defined at one side, a light guiding part (LWG) extending from the one side to an opposite side of the one side, and a light radiating part (LOT) defined on one plane surface. The light radiator (VHOE) is disposed on the light radiating part (LOT). The first light source (LS1) is disposed as facing the light entering part (LIN). The light collimator (WLC) is disposed on the light entering part (LIN) as facing the first light source (LS1). The light collimator (WLC) receives an expanding light from the first light source (LS1), converts the expanding light into a collimated light, and provides the collimated light to the light entering part (LIN).
