Abstract
Embodiments of the present disclosure provide an electronic paper, a display device, and a driving method. A plurality of first half-cup structures each includes charged dye particles with a single electric property are provided on the first driving backplane, a plurality of second half-cup structures each includes charged dye particles with a single electric property are provided on the second driving backplane; one first half-cup structure and the opposite second half-cup structures constitute a micro-cup structure, a electric property of the charged dye particles in the first half-cup structure is opposite to that in the second half-cup structure in the same micro-cup structure; a cross-sectional area of the respective second half-cup structures gradually decreases in a direction pointing from the second driving backplane to the first driving backplane; and a cross-sectional area of the respective first half-cup structures gradually decreases in an opposite direction.
