Abstract
Disclosed herein is a color electronic paper display device. The color electronic paper display device includes a barrier rib structure body that has a cavity partitioning rotating balls; and an electrode structure that is provided in the barrier rib structure body and applies voltage to the rotating balls, wherein the barrier rib structure body has a multilayer barrier rib structure formed of a lower barrier rib and an upper barrier rib, having different light absorptions.
Claims28
A color electronic paper display device, comprising:
- a barrier rib structure body that has a cavity partitioning rotating balls;
- and
- an electrode structure that is provided in the barrier rib structure body and applies voltage to the rotating balls,
- wherein the barrier rib structure body has a multilayer barrier rib structure formed of a lower barrier rib and an upper barrier rib, having different light absorptions.
A method for manufacturing a color electronic paper display device, comprising:
- forming a light absorbing layer;
- forming a light reflective layer on the light absorbing layer;
- forming a multilayer barrier rib structure having a lower barrier rib and an upper barrier rib by forming a cavity in the light reflective layer and the light absorbing layer;
- disposing rotating balls in the cavity;
- and
- forming an electrode structure that applies voltage to the rotating balls in the multilayer barrier rib structure.
A color electronic paper display device, comprising:
- a barrier rib structure body that has a cavity partitioning rotating balls;
- and
- an electrode structure that is provided in the barrier rib structure body and applies voltage to the rotating balls,
- wherein the barrier rib structure body includes:
- a lower barrier rib;
- an upper barrier rib that is disposed on the lower barrier rib;
- and
- a light absorbing layer that covers the lower barrier rib exposed to the cavity and partially surrounds the rotating ball.
A method for manufacturing a color electronic paper display device, comprising:
- forming a lower barrier rib that has a cavity partitioning rotating balls;
- forming a light absorbing layer that covers the lower barrier rib;
- forming an upper barrier rib that shares the cavity on the lower barrier rib other than the region where the cavity is formed;
- disposing rotating balls in the cavity;
- and
- forming an electrode structure that applies voltage to the rotating balls in a barrier rib structure body.
A method for manufacturing a color electronic paper display device, comprising:
- forming a barrier rib structure having a cavity partitioning rotating balls;
- forming a light absorbing layer that covers the barrier rib structure;
- removing the light absorbing layer in the rest region of the cavity, while maintaining the light absorbing layer in the cavity;
- positioning the rotating balls in the cavity;
- and
- forming an electrode structure that applies voltage to the rotating balls.
