This　letter　reports　an　autostereoscopic　three-dimensional　(3D)　flat　panel　display　system　employing　a　newly　designed　LCD-pixel-associated　parallax　barrier　(LPB).　The　barrier＇s　parameters　can　be　conveniently　determined　by　the　LCD　pixels　and　can　help　to　greatly　simplify　the　conventional　design.　The　optical　system　of　the　proposed　3D　display　is　built　and　simulated　to　verify　the　design.　For　further　experimental　demonstration,　a　508-mm　autostereoscopic　3D　display　prototype　is　developed　and　it　presents　good　stereoscopic　images.　Experimental　results　agree　well　with　the　simulation,　which　reveals　a　strong　potential　for　3D　display　applications.　©　2014　Tianjin　University　of　Technology　and　Springer-Verlag　Berlin　Heidelberg.
