Abstract
One example of a display device includes an electronic paper display, a counter-electrode, and a floating electrode. The electronic paper display is imageable by receiving charges on an imaging surface of the electronic paper display. The counter-electrode is opposite to the imaging surface of the electronic paper display. The floating electrode is capacitively coupled to the counter-electrode.
