Abstract

With the advancement of technology, color electronic paper displays have become the mainstream market in recent years. Thirty participants were recruited in this study to investigate the effect of color type (color, grayscale) and ambient illumination (200 lx, 750 lx, and 1500 lx) on legibility (search time, accuracy) and Positive and Negative Affect Schedule (PANAS) for different reading contents (charts, texts, and charts with texts [comics]). The results indicated that color type was significant on search time for charts and texts, significant on accuracy for texts and comics, and significant on PANAS for the three reading contents, while color displays performed better than grayscale displays. In addition, ambient illumination was significant on search time and PANAS for the three reading contents, and significant on accuracy for texts. The results showed that, at 200 lx, color charts and comics were recommended for reading. The results indicated that more than 750 lx was suitable for people to read charts. On the other hand, 1500 lx provided better legibility and a positive affect for people to read texts and comics. The results of this study could serve as a reference for the necessity of color electronic displays and the recommendation of suitable ambient illuminations with different reading contents.

颜色和环境光照对彩色电子纸显示屏可读性和正负情感表的影响
随着科技的进步,彩色电子纸显示屏近年来已成为市场主流。本研究招募了 30 名参与者,调查不同颜色类型(彩色、灰度)和环境照度(200 lx、750 lx 和 1500 lx)对不同阅读内容(图表、文本和带文本的图表[漫画])的可读性(搜索时间、准确性)和正负情意表(PANAS)的影响。结果表明,在三种阅读内容中,颜色类型对图表和文本的搜索时间有显著影响,对文本和漫画的准确性有显著影响,对 PANAS 有显著影响,而彩色显示器的表现优于灰度显示器。此外,环境照度对三种阅读内容的搜索时间和 PANAS 有显著影响,对文本的准确性有显著影响。结果显示,在 200 lx 下,建议阅读彩色图表和漫画。结果表明,750 lx 以上适合人们阅读图表。另一方面,1500 lx 的清晰度更高,对人们阅读文本和漫画有积极影响。这项研究的结果可以为彩色电子显示屏的必要性和推荐适合不同阅读内容的环境照明提供参考。
