## Abstract

There is provided an information display device making it possible to improve the reliability of a display against an external force. The information display device includes a case portion for displaying time information in a predetermined operation mode, and a band portion to be worn on an arm, and includes one piece of thin display inside the case portion and the band portion. Inside the band portion, the thin display, a metal sheet, and a resin sheet are laminated. The present technology can be applied to an information display device, etc., for example.

## Claims

### Claim 1

An information display device comprising:
a time information presentation portion configured to display time information;
a band portion configured to be worn on an arm;
a detection unit configured to detect a movement of the information display device; and
a display control unit configured to control display by a thin display,
wherein the information display device includes one piece of the thin display inside the time information presentation portion and the band portion,
wherein the thin display, a metal sheet, and a resin sheet are laminated inside the band portion,
wherein the display control unit is further configured to stop updating contents displayed by the thin display when a movement of the information display device is not detected for a predetermined period,
wherein the thin display is arranged at a stress neutral point of the band portion, and
wherein the detection unit and the display control unit are each implemented via at least one processor.

### Claim 2 (depends on 1)

The information display device according to claim 1,
wherein a material of the metal sheet is stainless steel.

### Claim 3 (depends on 1)

The information display device according to claim 1,
wherein the metal sheet has a thickness within a range of 0.03 to 0.08 mm.

### Claim 4 (depends on 1)

The information display device according to claim 1,
wherein a material of the resin sheet is polyethylene terephthalate.

### Claim 5 (depends on 1)

The information display device according to claim 1,
wherein the resin sheet has a thickness within a range of 0.05 to 0.20 mm.

### Claim 6 (depends on 1)

The information display device according to claim 1,
wherein a base portion of the band portion covers lateral surfaces and a bottom surface of the laminate of the thin display, the metal sheet, and the resin sheet,
wherein a cover portion of the band portion covers an upper surface of the thin display, the upper surface being a display surface, and
wherein an upper surface of the base portion covering the lateral surfaces of the laminate of the thin display, the metal sheet, and the resin sheet and a bottom surface of the cover portion are bonded.

### Claim 7 (depends on 6)

The information display device according to claim 6,
wherein a material of the base portion is a material in which an elastomer material having high hardness and an elastomer material having low hardness are compounded at a predetermined compounding ratio.

### Claim 8 (depends on 7)

The information display device according to claim 7,
wherein the elastomer materials are thermoplastic polyurethane.

### Claim 9 (depends on 1)

The information display device according to claim 1, wherein
the band portion includes a metal reinforcement plate near a connection portion with the time information presentation portion.

### Claim 10 (depends on 1)

The information display device according to claim 1,
wherein the thin display is electronic paper.

### Claim 11 (depends on 1)

The information display device according to claim 1,
wherein the thin display is an organic electroluminescent display.

### Claim 12 (depends on 1)

The information display device according to claim 1,
wherein the thin display is a liquid crystal display.

### Claim 13

A display control method comprising:
displaying time information by a time information presentation portion of an information display device connected to a band portion of the information display device that is configured to be worn on an arm, wherein the information display device includes one piece of the thin display inside the time information presentation portion and the band portion, and the thin display, a metal sheet, and a resin sheet are laminated inside the band portion;
detecting a movement of the information display device; and
controlling display by a thin display,
wherein controlling the display includes control to stop updating contents displayed by the thin display when a movement of the information display device is not detected for a predetermined period, and
wherein the thin display is arranged at a stress neutral point of the band portion.
