本論文主要在討論如何設計出符合M-3DI(Metadata 3D Initiative)規範的快門式三維立體眼鏡,並以此為前提來實現出低工作耗電、長待機時間並有著良好影像體驗同步系統的快門式三維立體眼鏡。論文中亦提出了一個不同於應用在大型液晶螢幕上之過載驅動法的反相驅動法來驅動快門式眼鏡,期望能夠改善快門式三維立體眼鏡上影響觀賞體驗的重要因素-響應時間。在此我們提出了兩種不同方式的反相驅動法,其中第一種反相驅動法明顯的改善了延遲時間,而第二種驅動法則可小幅度改善了液晶鏡片的上升時間,由於M-3DI計畫對於液晶鏡片的命令回應時間(Command to Response Time)限制較為嚴苛,因此藉由這兩個方法我們將可更容易的達到該計畫之規格要求。我們也嘗試著將一般常見的轉阻放大器、波峯偵測器及比較器,相互搭配組成浮動比較器,藉由這個浮動比較器,我們成功的設計出一個比市售產品擁有更高靈敏度與動態範圍的快門式眼鏡同步訊號感測線路。另外我們在進行相關實驗時,發現到了每一片液晶鏡片的響應時間都有著相當大的誤差量,而為了能夠實作出符合M-3DI規格之快門式眼鏡裝置,該誤差量已經讓我們不能去忽視它了,因此為了因應液晶鏡片個體的響應時間誤差,我們設計出了校驗治具,該治具可用來校正並驗證快門式三維立體眼鏡在影像顯示應用時的對比度、透光率及命令回應時間,我們期待可以藉由該治具的校正,來實現出符合規範且功能性一致的快門式三維眼鏡。

This thesis aims to develop a design which meets the standard of Metadata 3D Initiative (M-3DI) for 3D shutter glasses, which can subsequently serve as prerequisite for realizing a 3D shutter glasses having low power consumption during operation, long standby time, and is good at providing image experience synchronization system. Here, this thesis proposed inverse pulse driving method to drive the shutter glasses which was different from one applied to liquid crystal display(LCD.) driven by over driving method, in order to improve response time of 3D glasses which was a critical factor of application experience for user. In this thesis, we proposed two inverse pulse driving methods. One of them significantly improved delay time, while the other slightly improved rising time for the liquid crystal lenses. Since M-3DI had severer requirement for command to response time, the above two methods could make it easier to meet specification of this project. We also tried to coordinate common transimpedance amplifier circuit, envelope detector circuit and MCU internal comparator into floating comparator. With this comparator, we successfully designed a synchronized signal detection circuit for the shutter glasses whose sensitivity and dynamic range were even higher than that of market available products. Besides, we found during experiment that each piece of liquid crystal display had rather large error in response time which alerted us to no more ignore it. In order to cope with the error of response time of each liquid crystal lenses, we designed a calibration tool to calibrate and verify contrast, light transmittance, and command to response time of the images displayed during application of the 3D shutter glasses. The researchers expected that this tool helped to realize a 3D shutter glasses which met the standard and was consistent in function.
