AU Optronics (AUO) Corp showcased a device made by attaching a flexible thin-film photovoltaic (PV) battery to the back of flexible electronic paper (e-paper) at FPD International 2011.
The company calls the device “Un-plugged Flexible E-paper Display,” meaning that it does not require a power plug.
AUO has sandwiched a flexible organic TFT display to a thin-film photovoltaic battery to create a self-powered e-reader that can be bent and twisted just like a piece of paper.
The combination of PV battery and e-paper, whose power consumption is small, has been considered promising for some time. And a wristwatch equipped with both of them has already been released.
