Abstract

The present disclosure relates to a portable attachment and communication system that enable a desired image to be displayed with flexibility and lower power consumption in an article worn or carried by a human.
The portable attachment is an article including a display body made of an electrophoretic display, the article being carried or worn by a user. The present disclosure can be applied to, for example, a portable attachment, etc. Examples of the portable attachment carried by a user are a bag, a wallet, a key holder, etc. Examples of the portable attachment worn by the user are a hair accessory, a tie, a watch, clothing, etc.

First claim

The invention claimed is:

1. A portable attachment that is an article including a display body made of an electrophoretic display, the article being carried or worn by a user, the portable attachment comprising:
a state detection unit configured to detect a predetermined state of the portable attachment,
wherein an applied voltage of the electrophoretic display is changed according to a detection result of the state detection unit, such that a time interval between changes of the applied voltage is changed in response to a detection that a capacity of a battery of the portable attachment is less than or equal to a predetermined level.

2. The portable attachment according to claim 1 , comprising:
an operation detection unit configured to detect an operation of the user,
wherein an applied voltage of the electrophoretic display is changed according to the operation of the user detected by the operation detection unit.

3. The portable attachment according to claim 1 , comprising:
a communication unit configured to wirelessly communicate with another communication apparatus,
wherein an applied voltage of the electrophoretic display is changed according to a received signal received by the communication unit.

4. The portable attachment according to claim 3 , wherein
the communication unit receives design data from the other communication apparatus, and
the applied voltage of the electrophoretic display is changed on the basis of the design data and thereby an image of the display body is changed.

5. The portable attachment according to claim 3 , wherein
the communication unit extracts power from the received signal, and
the applied voltage of the electrophoretic display is changed using the extracted power.

6. The portable attachment according to claim 3 , wherein the communication unit wirelessly communicates with the other communication apparatus using near field communication (NFC).

7. The portable attachment according to claim 1 , wherein the portable attachment is a bag.

8. The portable attachment according to claim 7 , wherein a shape of the bag is changeable to a polyhedral shape and a planar shape.

9. The portable attachment according to claim 1 , wherein a film on which a predetermined pattern or character is drawn is attached to an upper surface of the electrophoretic display.

10. The portable attachment according to claim 1 , wherein the display body includes a color filter on a surface side of the electrophoretic display.

11. The portable attachment according to claim 1 , wherein a control terminal including at least a drive control unit configure to control an applied voltage of the electrophoretic display is separated from the display body and a connection port of the control terminal is connected to an electrode layer of the electrophoretic display by the control terminal sandwiching the display body.

12. The portable attachment according to claim 1 , wherein the display body of a strip shape is woven.

13. The portable attachment according to claim 1 , wherein the electrophoretic display has a plurality of segments.

14. The portable attachment according to claim 13 , wherein the plurality of segments are arrayed in a two-dimensional array shape.

15. The portable attachment according to claim 1 , wherein the display body also performs display on a rear side of the electrophoretic display.

16. The portable attachment according to claim 15 , wherein the display body includes a color filter on the rear side of the electrophoretic display.

17. A communication system comprising:
a portable attachment that is an article carried or worn by a user; and
a terminal apparatus, wherein
the portable attachment includes
a communication unit configured to wirelessly communicate with the terminal apparatus,
a display body made of an electrophoretic display and configured to perform display based on design data received by the communication unit, and
a state detection unit configured to detect a predetermined state of the portable attachment,
wherein an applied voltage of the electrophoretic display is changed according to a detection result of the state detection unit, such that a time interval between changes of the applied voltage is changed in response to a detection that a capacity of a battery of the portable attachment is less than or equal to a predetermined level, and
the terminal apparatus transmits the design data to the communication unit.

18. The communication system according to claim 17 , wherein the terminal apparatus further includes a design data creation unit configured to create the design data.

19. The communication system according to claim 18 , wherein the design data creation unit creates the design data on the basis of segment data of the portable attachment.
