由於能提供觀賞者直接的立體效果不用經由特殊眼鏡，裸眼立體3D裝置被視為下一世代顯示器。製作容易的視差光閘是主流的解決方法。到目前為止，大部分的3D顯示器都放置在室內，幾乎很少設置在戶外，其主要的原因為亮度不足。然而高亮度的LED顯示器被廣泛地運用在大型購物商場、展場、體育場以及都市商業區。結合3D功能的LED顯示器希望在未來能廣泛的被運用。本論文旨在發展視差光閘以及對應的3D撥放器之裸眼LED立體顯示系統。本文也提出了視差調整以及以區域為基礎的光串擾降低技術來提升觀賞的品質。這兩種方式不只適用於我們的LED立體顯示系統，也可運用於一般的裸眼立體螢幕。在實驗結果中證明我們的方法能有效的減少光串擾以及產生更舒適的立體效果。

Autostereoscopic displays are considered as the next generation 3D displays since audiences can feel more comfortable without the restriction of wearing glasses. Due to the easy production, parallax barrier is a common solution for autostereoscopic displays. So far, most 3D displays are set indoors, but few 3D displays are set outdoors due to the limitation of brightness. However, LED displays with higher brightness are used in many public areas such as shopping malls, exhibitions, stadiums, and downtowns. It is hoped that LED displays will equipped with 3D functionality and spread widely in the future. To achieve this, this thesis is dedicated to develop an autostereoscopic LED display system based on the corresponding parallax barrier and 3D player. To enhance the visual quality, this thesis also proposed two novel crosstalk reduction methods for general stereoscopic displays by using disparity adjustment and region-based crosstalk reduction methods. Experimental results show that our methods can effectively reduce the perceived crosstalk and generate satisfying 3D effect on the established 3D LED system.
