https://newatlas.com/technology/color-e ... ess-power/E Ink screens are not only kinder to your eyes, but offer great battery life due to their low power draw. But a new display from Digital View doesn't have a battery at all, and gets the juice it needs from an overhead Wi-Charge wireless power module.
Before all you digital bookworms get too excited, this development will have limited appeal for e-reader devices – as screens won't refresh and pages won't turn when out of power transmission range. But it could be a good shout for advertising panels in retail stores, information points in museums or art galleries, timetables at transport hubs or dynamic notices in meeting rooms.
The onboard Wi-Fi can receive remote updates for the always-on display while an overhead Wi-Charge module wirelessly powers a number of units simultaneously – with full draw for each display reported to be around 500 mW for Wi-Fi connection, image/info retrieval and write, though a standby mode needs significantly less.
