The display screen is a special "surface-stabilized, cholesteric-texture liquid-crystal display" (SSTC-LCD), which retains the last page image even when the power is turned off. This means that electric current is only needed when turning the page, so the unit uses very little power, and can run through over 10,000 page turns on two AA batteries. This is equivalent to two months 'continuous reading.
顯示螢幕採用特殊的「雙穩態膽甾型液晶顯示螢幕」，電源關閉時，仍可保持之前的最後一個畫面，只有在翻頁時，才需要用到電力，耗電量低，二顆三號電池可以翻閱一萬頁以上的書籍，連續閱讀二個月。
