摘要

隨著近幾年來影像顯示器產業蓬勃發展，技術不斷的提升，人類對追求立體影像顯示的渴望又再度被燃起。頭戴式立體顯示器是目前已經很成熟的技術，但是使用者必須佩戴立體眼鏡，容易造成不便和不適。因此，裸眼式立體顯示器被認為是次世代顯示器發展之主要目標。

本研究針對以液晶顯示器為基礎的裸眼式立體顯示技術中的自立體顯示空間多工方式，提出一個高效率且高解析度的解決方案。藉由放置於液晶面板上面的傾斜遮罩，可以平衡當平面顯示器應用於立體顯示器時產生的垂直與水平方向的解析度衰減。而為了同時兼顧高解析度與高效率的議題，基於傾斜遮罩的液晶畫素設計被應用於這份研究中。在此研究中提出了兩種方式來提高立體顯示器的效率，一是使用具有高度方向性的液晶結構來提高在視差自立體顯示器中各個視域的亮度，二是修改液晶畫素中的電子元件，使其能夠降低視堿重疊等影響畫質的因素。經由設計模擬分析並量測實作的液晶面板，可驗證此兩種基於傾斜遮罩的液晶畫素修改確實可行，增加液晶面板應用於立體顯示器之下的效率。

Human see this world stereoscopically, we are trying to reproduce the visual experiences from what we see from the real world. Basic principles of most 3D displays technologies were discovered a hundred years ago, but the 3D displays have not yet been put into mass production due to several problems, such as the low 3D resolution, complicated mechanism, and inconvenience of wearing glasses, etc. Nowadays many researchers are getting interested in 3D displays again because the performance of flat panel display, especially liquid crystal display (LCD) has been largely improved. This mature display technology accompanying with the new-development method can overcome the problem of the previous 3D technology.

This research proposes a solution for high efficiency high resolution liquid crystal (LC) panel for autostereoscopic 3D display with wide-view and high 3D resolution. The slanted barrier is applied on a LC panel for sharing the resolution reduction in both horizontal and vertical direction. In order to reach a high resolution with high efficiency, a new design of the LC pixel layout is necessary. The pixel design is based on the slanted barrier. The LC pixel with high directional emission profile can not only improve efficiency but also eliminate some deficiencies that affect the image quality in conventional parallax barrier design. By applying the slanted barrier and the pixel layout, we can overcome the issue of low resolution and serious resolution reduction in horizontal direction on conventional straight barrier design and have a LC panel which is more suitable for the application of high light efficiency parallax barrier type 3D display.
