1. 電子紙具備「護眼」和「省電」兩大優勢，是最像「紙」的新科技。
E-paper has two main advantages: it saves power and doesn’t cause eyestrain. It is the display technology that most closely matches the characteristics of paper.
◎ eyestrain n.眼睛疲勞
Proper lighting can reduce eyestrain and glare.
2. 薄薄的一張紙，可以隨興改變顯示內容，裡面的照片還是可動的影像，那在巫師世界是理所當然，但在現實生活裡，科學家正與企業家聯手，一步一步地實現小說家筆下的想像。
Just one page long, the paper could show different content on demand, and its pictures even moved! The wizarding world took this for granted, but scientists are currently working with corporations to bring this fictional, fanciful idea to life in the real world, too.
◎ on demand 一經要求；在有需求時, 應顧客要求即可提供的
At the 2022 Consumer Electronics Show in the United States, the German automotive company BMW revealed a concept car called the iX Flow that used e-paper technology developed by E Ink to change its color on demand.
