來自英特爾、華盛頓大學(xué)和美國馬薩諸塞大學(xué)的團(tuán)隊開發(fā)基于電子墨水的輔助顯示屏，不僅可以從手機(jī)的無線NFC連接下載文本和圖像，而且可以在此過程中獲取所需的最少電量進(jìn)行顯示屏更新。
第二顯示屏的電子墨水屏使得這一切都成為可能，因為它只有在進(jìn)行屏幕更新的時候才需要用電。然而，不足之處是第二屏上永遠(yuǎn)是不變的靜態(tài)黑白圖像。但假如你需要便捷地保存地址、電話號碼或者地圖的截屏，不需要給LCD通電即可完成。
This NFC-Powered Bonus E-Ink Display for Your Phone Needs No Batteries
No matter what you're doing at a computer, two displays are always better than one, and that could soon be true for your mobile devices as well. Prototypes of dual-display smartphones have already been demonstrated, but researchers have now revealed a wireless second display for your mobile devices that magically sucks the minimal power it requires from a wireless NFC connection.Teams from Intel, the University of Washington, and the University of Massachusetts developed the e-ink based secondary display which can not only download text and images from a phone's wireless NFC connection, but also steal the minimal power it needs to update its own display in the process.
The second display's e-ink screen is what makes this whole approach possible, since it only needs power when it's updating what's on screen. So the downside is that you're stuck with static black and white images on the second display. But if you needed to keep an address or phone number handy, or a screenshot of a map, it allows you to do so without leaving your smartphone's battery-draining LCD powered on.
