Abstract
Abstract. We propose an effective and efficient method that reduces the crosstalk level in autostereoscopiclight-emitting diode (LED) displays by optimizing the pixel arrangement of the associated two-dimensional(2-D) LED panel. In the proposed method, first a series of parallax barrier patterns, based on predesignatedLED packaging units, are designed and simulated by sequentially regulating the width of black stripes onthe 2-D LED panel. This design principle removes the black stripes from conventional autostereoscopicLED display pixels for optimal parallax barrier calculation. Furthermore, the mathematical relationship betweenaveragecrosstalklevelandvisualfluxdensityisobtainedfromthesimulation.Amathematicalfittingmethodthatincludes a cubic fitting function is finally applied to achieve proper pixel arrangement in the 2-D LED panel. Thesimulation results obtained for a dual viewpoint autostereoscopic LED display system indicate that the mostsuitable valuefor the widthof the blackstripesiswithin the rangeof 3.17604to 3.34277 mm,withalight-emittingpixelwidthof2mm.Thismethodcaneffectivelyguidethe2-DLEDpanel’sdesignandresultinhighperformanceautostereoscopicthree-dimensionalLEDdisplays,whichwillhavebroadapplicationprospectsinthenearfuture.
