本論文研究的目的,在探討目前液晶顯示器LCD中3D顯示器的技術問題,研究方向以平面顯示器可產生3D顯示效果之成效及視覺效果提升之結果。
此論文研究之方向,主要是利用Glass Parallax Barrier搭配一組LCM(LCD Module)模組製作成3D數位像框,但因Parallax Barrier的工作原理會讓LCM本身亮度降低50%,故本文特別針對改善背光源亮度問題提出討論。
本論文針對提升3D液晶顯示器亮度之議題,提出使用LED Backlight搭配DBEF來減少功率消耗、提高光源亮度之運用。

The purpose of this thesis is to discuss the technical problems of LCD, especially 3D. The research direction focuses on 3D display effects and improved visual effects.
This thesis mainly uses Glass Parallax Barrier to go with 3D digital photo frame made by LCM (LCD Module). The brightness of LCM will decrease 50%, due to the Parallax Barrier method. Therefore, this thesis will have the further discussion on backlight improvement.
Besides the improvement of 3D display brightness issue, this thesis also mentions the applications of LED backlight and DBEF to diminish consumed power and enhance the backlight brightness.
