Abstract
Embodiments of the present invention are directed to systems and methods for writing on electronic paper (“e-paper”) and display platforms implemented with e-paper.

The erasing unit is configured to erase information stored in the electronic paper. The system also includes a writing unit connected to the writing module and is configured to write information to the electronic paper.
