Abstract

An electrophoresis display apparatus includes an electronic-ink (E-Ink) layer, a passive-matrix substrate, and a conducting layer. The passive-matrix substrate has an electrode surface, and the electrode surface has a plurality of electrodes. The conducting layer has a predetermined shape. The conducting layer is disposed between the electronic-ink layer and the electrode surface of the passive-matrix substrate and is used for transmitting the signals on the electrodes contacting the conducting layer to the electronic-ink layer, so that the electronic-ink layer can display an image with the predetermined shape.

Claims

1. An electrophoresis display apparatus, comprising:

an electronic-ink layer;

a passive-matrix substrate, having an electrode surface, the electrode surface comprising a plurality of electrodes; and

a conducting layer, having a predetermined shape, the conducting layer being disposed between the electronic-ink layer and the electrode surface of the passive-matrix substrate.

2. The electrophoresis display apparatus according to claim 1, further comprising:

a cover, configured for covering a display area of the electronic-ink layer, the cover having at least one of a predetermined pattern and a predetermined word, a part of the cover corresponding to the predetermined shape of the conducting layer displayed on the electronic-ink layer being hollowed.

3. The electrophoresis display apparatus according to claim 1, further comprising:

a cover, configured for covering a display area of the electronic-ink layer, the cover having at least one of a predetermined pattern and a predetermined word, a part of the cover corresponding to the predetermined shape of the conducting layer displayed on the electronic-ink layer being transparent.

4. The electrophoresis display apparatus according to claim 1, further comprising:

a cover, configured for covering a part of a display area of the electronic-ink layer and showing the predetermined shape of the conducting layer displayed on the electronic-ink layer, the cover having at least one of a predetermined pattern and a predetermined word.

5. The electrophoresis display apparatus according to claim 1, wherein the materials of the conducting layer and the electrodes are the same.

6. The electrophoresis display apparatus according to claim 5, wherein the material of the electrodes comprises at least one of Copper, Silver, and Carbon.

7. The electrophoresis display apparatus according to claim 1, wherein the form of the conducting layer comprises at least one of solid form, liquid form, and colloidal form.

8. The electrophoresis display apparatus according to claim 7, wherein the conducting layer is able to be set by way of screen printing, slit coating or manual coating.

9. The electrophoresis display apparatus according to claim 1, wherein the electronic-ink layer is configured to display at least one of a black-and-white image and a color image.

10. The electrophoresis display apparatus according to claim 1, wherein the area of the conducting layer is smaller than that of the electronic-ink layer and that of the passive-matrix substrate.
