Claim:
A 3D display system, comprising: a display panel for displaying a display image, the display panel having a first side and an opposing second side; a light source for providing illumination to the display panel through the second side; and a light directing device comprising a light control panel located between the light source and the display panel, the light directing device configured to direct light from the light source passing through the light control panel toward the display panel at least in a first direction and a different second direction, wherein the light control panel comprises a shutter plate, the shutter plate comprising a plurality of first shutter segments and a plurality of second shutter segments alternately arranged, each of the first shutter segments and the second shutter segments is operable in an open state to allow light to pass through and in a closed state to prevent light from passing through, wherein the display panel is configured to display a left-view image and a right-view image in an alternate fashion, and wherein the first shutter segments are operated in the open state and the second shutter segments are operated in the closed state when the right-view image is displayed, and the first shutter segments are operated in the closed state and the second shutter segments are operated in the open state when the left-view image is displayed and wherein the light directing device further comprises a lenticular screen located between the display panel and the shutter plate, the lenticular screen comprises a plurality of lenticules, each of the lenticules having a lenticule base of constant width, wherein the lenticular screen is positioned such that at least in some of the lenticules the lenticular base covers at least part of a first shutter segment and at least part of an adjacent second shutter segment, wherein the first shutter segment and the adjacent second shutter segment define a shutter pitch and the lenticule base of constant width defines a lenticular pitch of the lenticular screen, wherein the shutter pitch is substantially equal to or greater than the lenticular pitch.
