exactly Dulin....
do you remember one of the big uses touted for the EPD/Bi-stable panels was also store shelf price and informational tags? The idea I recall reading was such tags and info displays could be adjusted with either a hand held or as a networked device that would periodically(?) connect to the in-house network to update the tags price and/or general info. Thus reducing errors and handling things like sale prices vs. regular pricing.
No matter what this type of display tech can and will reduce energy use if businesses ever have the funding to begin moving to them across the board.
Heck even a watch, which in all honesty rarely needs a true second hand or even secound counter...but a simple wrist watch could last a loooong time if the display was updated on once a minute (or whatever interval the user selects, even on demand). There are simply so many uses for this sort of display...billboards to entire store windows to the lowly shelf tag for items...I wonder if people here, because we focus on reading so much, neglect to see the real value as far more than our devices.
I can't wait to see the power requirements of home TV's once there are full color panels to be had. Who knows one day they panels themselves will be produced on demand at the point of sale in whatever size the buyer desires. Then one just wanders over to the "picture/TV frame" deparement of the store to hold your new panel. (had to toss in a bit of SF into the mix, just, well, because.)
