本研究旨在探討電子紙顯示器在不同光源、環境照度、極性及字型下的視覺績效與視覺疲勞。在視覺績效方面，照度對搜尋時間有顯著影響，當環境照度為300lux時，電子紙顯示器的搜尋時間將遽增許多，環境照度在700lux以上的搜尋時間較短且趨於穩定。顯示媒介、極性及顯示媒介與字型的交互作用對正確率有顯著影響。膽固醇液晶顯示器的正確率低於電泳式電子墨水顯示器與普通紙張，陰性呈現的正確率顯著低於陽性呈現，電子紙顯示器以新細明體顯示會有較高的正確率，而紙張則是以標楷體呈現會有較高的正確率；在視覺疲勞方面，光源、顯示媒介及其交互作用對於閃光融合閾值的變化沒有顯著影響，對於主觀視覺疲勞評量亦沒有顯著影響。

This study explored the effects of light source, ambient illuminance, font type, polarity and display media on visual performance and visual fatigue. In terms of visual performance, the results showed that ambient illuminance had significant effects on search time. With the increase of ambient illumination, search time decreased, especially from 300lux to 700lux. Display media, polarity and the interaction of display media and font type had significant effects on accuracy. Accuracy was lower for Chlorestic Liquid Crystal display than for other display types, and for negative presentation than for positive presentation. E-paper had higher accuracy with New-Xi-Ming font type, and paper had higher accuracy with Biao-Kai font type. As for visual fatigue, results showed that light source and display medium and the interaction of light source and display medium had no significant effects on the change of CFF (Critical Flicker Fusion).and subjective visual fatigue.
