Abstract
Disclosed herein is an electronic paper display device, including: a barrier rib structure having a plurality of partitioning spaces arranged in a matrix form; and a plurality of rotating balls each disposed within the partitioning spaces in a form in which a first hemisphere and a second hemisphere are coupled, wherein the rotating ball is rotated in a preset direction by a shape of the partitioning space. Herein, the electrocic paper display device forms a cavity in an asymmetrical shape to induce the rotating ball to be rotated in one direction, thereby making it possible to easily control the rotating ball.
Claims18
An electronic paper display device, comprising:
- a barrier rib structure providing a plurality of partitioning spaces;
- and
- a plurality of rotating balls each disposed within the partitioning spaces in a form in which a first hemisphere and a second hemisphere are coupled,
- wherein the rotating ball is rotated in a preset direction by a shape of the partitioning space.
An electronic paper display device, comprising:
- a barrier rib structure providing a plurality of partitioning spaces partitioned by barrier ribs;
- and
- a plurality of rotating balls formed by coupling a first hemisphere to a second hemisphere,
- wherein an interval between the rotating ball and the inner surface of the partitioning space is larger in a second direction than in a first direction, the second direction being different from the first direction.
