Display device

A display device comprising:

• a support structure;
• a ground electrode arranged on the support structure;
• an electronic paper display arranged on the ground electrode, the electronic paper display imageable by receiving charges on a charge receiving layer of the electronic paper display;
• and
• a ground access stripe electrically coupled to the ground electrode, the ground access stripe exposed completely around the support structure on the outer edge of the support structure and substantially orthogonal to the electronic paper display.

A system comprising:

• a writing module comprising a writing unit, a first conductive roller, and a second conductive roller, the writing module to write to a display device, the display device comprising:
• a support structure;
• a ground electrode arranged on the support structure and exposed at an edge of the support structure;
• and
• an electronic paper display arranged on the ground electrode, the electronic paper display imageable by receiving charges on a charge receiving layer of the electronic paper display from the writing unit,
• wherein the first conductive roller and the second conductive roller are to contact the ground electrode to provide a ground return path that allows charges received on the charge receiving layer to flow to the ground electrode during writing of the electronic paper display as the writing module and the display device are moved relative to each other.
