摘要
本研究旨在探討電子紙顯示器在不同光源、照度、字體大小以及行間距下的視覺績效與視覺疲勞。在視覺績效方面，顯示媒介、字體大小、行間距對搜尋時間有顯著影響，電泳式電子墨水顯示器在搜尋時間的表現優於膽固醇液晶顯示器，當字體大小為3.0mm時對搜尋時間最短而當字體大小為2.0mm時對搜尋時間最長，當行間距66％時對於搜尋時間較行間距50％時短。照度、顯示媒介、字體大小、行間距對正確率有顯著影響，當環境照度為1500lux時正確率最高，電泳式電子墨水顯示器的正確率高於膽固醇液晶顯示器。字體大小為2.0mm時正確率最低，字體大小為3.0mm時正確率最高、行間距為66％時的正確率高於行間距50％時的正確率。在視覺疲勞方面，光源、照度皆對閃光融合閾值呈現不顯著。光源及照度對主觀視覺疲勞評量亦呈現不顯著影響。將電子紙顯示器設定為3.00mm字體和66％呈現，並在1500lux的照度下，有較佳的視覺績效。

This study explored the effects of light source, ambient illuminance, font size and line space on visual performance and visual fatigue. For visual performance the results showed that display medium, font size, line space had significant effects on search time. Electrophoretic electronic ink display had shorter search time than Chlorestic Liquid Crystal display.Search time for font size 3.0mm was shorter than font size 2.0mm; for the line space 66％ than for 50%.Ambient Illuminance, display medium, font size, line space had significant effects on accuracy. Accuracy was highest for 1500lux; accuracy of electrophoretic electronic ink display was higher than Chlorestic Liquid Crystal display; accuracy was lowest for font size 2.0mm and highest for font size 3.0mm; and accuracy was higher for line space 66％ than 50％. As for visual fatigue, results showed that light source and ambient illuminance had non-significant effects on change of CFF (Critical Flicker Fusion). Light source and ambient illuminance also had non-significant effect on subjective visual fatigue.Set the E-paper font size at 3.00mm, line space at 66％, and ambient illuminance at 1500lux, could get better visual performance. Reading electronic paper under fluorescent lamp and high ambient illuminance, could result in less visual fatigue.
