Abstract

Disclosed is a display device characterized by comprising a frame having a ring shape and mounted on a user and a display unit arranged along the frame over substantially its entire circumference. The display device comprises a controller having judgment means for judging which position is the position where the display unit is arranged in relation to another display unit on the basis of a signal from a receiver, storage means for storing positional information in the judgment means, and display control means for controlling the display of the display unit on the basis of the positional information stored in the storage means. Further, disclosed is a display system comprising the display device and a communication unit for communicating with the display device.

Claims (42)

1. A display device comprising:

a first frame having a first outer peripheral surface and a first side peripheral surface, said first frame having a ring shape being configured to be mounted on a user;

a first display unit being arranged along said first outer peripheral surface over substantially an entire circumference of said first frame to display information; and

a first sensor being arranged on said first side peripheral surface to perform radio communication,

said first sensor having a motion sensor, and

said first display unit having a display change device to change a display via a signal from said motion sensor.

2. The display device according to claim 1 , further comprising,

a second frame that has a second outer peripheral surface and a second side peripheral surface, said second frame having a ring shape and being configured to be mounted on said user,

a second display unit arranged along said second outer peripheral surface over substantially an entire circumference of said second frame, and

a second sensor arranged on said second side peripheral surface to perform radio communication with said first sensor.

3. The display device according to claim 2 , wherein

said first display unit has a first inner periphery arranged on a peripheral surface of said first frame, a first fold that integrally connects with one end of said first inner periphery, and a first outer periphery arranged on said first inner periphery over substantially an entire circumference thereof and integrally connecting with said first fold, and

said second display unit has a second inner periphery arranged on a peripheral surface of said second frame, a second fold that integrally connects with one end of said second inner periphery, and a second outer periphery arranged on said second inner periphery over substantially an entire circumference thereof and integrally connecting with said second fold.

4. The display device comprising:

a first frame having a first outer peripheral surface and a first side peripheral surface, said first frame having a ring shape being configured to be mounted on a user;

a first display unit being arranged along said first outer peripheral surface over substantially an entire circumference of said first frame to display information;

a first sensor being arranged on said first side peripheral surface to perform radio communication;

a second frame that has a second outer peripheral surface and a second side peripheral surface, said second frame having a ring shape and being configured to be mounted on said user,

a second display unit arranged along said second outer peripheral surface over substantially an entire circumference of said second frame, and

a second sensor arranged on said second side peripheral surface to perform radio communication with said first sensor,

said first frame including a first groove extending in a circumferential direction on an outer peripheral surface thereof, said first display unit being arranged within said first groove, and

said second frame including a second groove extending in a circumferential direction on an outer peripheral surface thereof, said second display unit being arranged within the second groove.

5. The display device according to claim 2 , wherein

said first outer periphery has a first display panel,

said first inner periphery has a first flexible base formed of a flexible member and a first electronic component arranged on said first flexible base,

said second outer periphery has a second display panel, and

said second inner periphery has a second flexible base formed of a flexible member and a second electronic component arranged on said second flexible base.

6. The display device comprising:

a first frame having a first outer peripheral surface and a first side peripheral surface, said first frame having a ring shape being configured to be mounted on a user;

a first display unit being arranged along said first outer peripheral surface over substantially an entire circumference of said first frame to display information;

a first sensor being arranged on said first side peripheral surface to perform radio communication;

a second frame that has a second outer peripheral surface and a second side peripheral surface, said second frame having a ring shape and being configured to be mounted on said user;

a second display unit arranged along said second outer peripheral surface over substantially an entire circumference of said second frame, and

a second sensor arranged on said second side peripheral surface to perform radio communication with said first sensor,

said first sensor having at least one first LED, a plurality of first photodiodes, and a rotational position detector to detect a rotational position of said first frame via signals from said first photodiodes, and

said second sensor having at least one second LED, a plurality of second photodiodes, and a rotational position detector to detect a rotational position of said second frame via signals from said second photodiodes.

7. The display device according to claim 2 , wherein

said first sensor has a relative rotational position detector to detect a rotational position of said first frame relative to said second frame, and

said first display unit has a first display image control to control a display image via information relating to said relative rotational position detected by said first sensor.

8. The display device according to claim 7 , wherein

said second sensor includes a relative rotational position detector to detect said rotational position of said second frame relative to said first frame, and

said second display unit includes a second display image control to control a display image via information relating to said relative rotational position detected by the second sensor.
