Abstract:
A directional backlight unit, a three-dimensional (3D) image display apparatus, and a 3D image displaying method are provided. The directional backlight unit includes a light guide plate having an emission surface on which a plurality of grating elements including first and second groups of grating elements are provided. The plurality of grating elements are arranged such that light beams emitted from the first and second groups of grating elements commonly propagate through a plurality of pixel points and respectively form first and second groups of view points of which corresponding regions do not overlap with each other.

Claim (Index 16):
A 3D image displaying method comprising:\n providing light to a light guide plate; arranging a plurality of grating elements on an emission surface of the light guide plate such that the plurality of grating elements are configured to externally emit the light from the emission surface; modulating emitted light beams by using a plurality of pixels of a spatial light modulator; and forming a plurality of view points by facilitating a propagation of light beams emitted from the plurality of grating elements through the plurality of pixels of the spatial light modulator, wherein at least two of the plurality of grating elements match with each pixel from among the plurality of pixels, two adjacent grating elements match with different pixels from among the plurality of pixels, and light beams emitted from the at least two grating elements propagate through one pixel matched with the at least two grating elements and then are simultaneously directed toward different view points among the plurality of view points.
