## Abstract

A bendable display method and device are provided. The bendable display device includes a display unit including a display screen, a sensing unit that senses a user manipulation, and a control unit that modifies a display of the display screen according to the user manipulation sensed by the sensing unit. The display device is bendable under external pressure into a rolled state in which the display screen of the display unit forms an outer wall, and the display unit displays the display on the display screen in the rolled state.

## Claims

### Claim 1

A bendable display device, comprising:
a display unit including a display screen;
a sensing unit that senses a user manipulation; and
a control unit that modifies a display of the display screen according to the user manipulation sensed by the sensing unit,
wherein the display device is bendable into a rolled state in which the display screen of the display unit forms an outer wall, and
wherein the display unit displays the display on the display screen in the rolled state.

### Claim 2 (depends on 1)

The display device of claim 1, wherein, when the user manipulation rotates the display device about an axis of rolling of the display device in the rolled state, the control unit moves a location of an object displayed on the display screen according to a direction of rotation.

### Claim 3 (depends on 2)

The display device of claim 2, wherein the control unit changes a shape of the object displayed on the display screen according to rotational speed.

### Claim 4 (depends on 1)

The display device of claim 1, wherein, when the user manipulation includes touching the display screen of the display device in the rolled state, and dragging or flicking in a direction in agreement with an axis of rolling, the control unit moves a location of an object displayed on the display screen according to the direction of the dragging or flicking.

### Claim 5 (depends on 1)

The display device of claim 1, when the user manipulation includes touching the display screen the display screen of the display device in the rolled state, the control unit sets an extension area with reference to a point of the touching on the display screen and extends a size of an object located within the extension area.

### Claim 6 (depends on 5)

The display device of claim 5, wherein, if the point of the touching is changed by rotation about the axis of rolling of the display device, the control unit changes the extension area with reference to the changed point of the touching

### Claim 7 (depends on 1)

The display device of claim 1, wherein, when the user manipulation includes touching the display screen of the display device in the rolled state, the control unit sets a shape changeable area with reference to a point of the touching on the display screen and changes the shape changeable area into a planar shape.

### Claim 8 (depends on 7)

The display device of claim 7, wherein the control unit displays additional information regarding an object displayed in the shape changeable area.

### Claim 9 (depends on 1)

The display device of claim 1, further comprising:
a rechargeable battery unit; and
a connector unit formed on a side of the display device to be connected to a charger, when the display device is in the rolled state,
wherein the display unit displays a state of the rechargeable battery unit during a recharge processing in the rolled state.

### Claim 10

A display method of a bendable display device including a bendable display unit, the method comprising:
displaying a display on a display screen of the display device in a rolled state;
sensing a user manipulation of the display device; and
modifying the display of the display screen according to the user manipulation,
wherein the display device is bendable under external pressure into a rolled state in which the display screen forms an outer wall.

### Claim 11 (depends on 11)

The display method of claim 11, wherein, when the user manipulation rotates the display device about an axis of rolling of the display device in the rolled state, modifying the display of the display screen comprises moving a location of an object displayed on the display screen according to a direction of rotation.

### Claim 12 (depends on 11)

The display method of claim 11, wherein modifying the display of the display screen further comprises changing a shape of the object displayed on the display screen according to rotational speed.

### Claim 13 (depends on 10)

The display method of claim 10, wherein, when the user manipulation includes touching on the display screen of the display device in the rolled state, and dragging or flicking in a direction in agreement with an axis of rolling, modifying the display of the display screen comprises moving a location of an object displayed on the display screen according to the direction of the dragging or flicking.

### Claim 14 (depends on 10)

The display method of claim 10, when the user manipulation includes touching the display screen, modifying the display of the display screen comprises setting an extension area with reference to a point of the touching on the display screen and extending a size of an object located within the extension area.

### Claim 15 (depends on 14)

The display method of claim 14, wherein, when he point of the touching is changed by rotation about the axis of rolling of the display device, modifying the display of the display screen further comprises changing the extension area with reference to the changed point of the touching

### Claim 16 (depends on 10)

The display method of claim 10, wherein, when the user manipulation includes touching the display screen in the rolled state, modifying the display of the display screen comprises setting a shape changeable area with reference to a point of the touching on the display screen and changing the shape changeable area into a planar shape.

### Claim 17 (depends on 16)

The display method of claim 16, further comprising displaying additional information regarding an object displayed in the shape changeable area.

### Claim 18 (depends on 10)

The display method of claim 10, further comprising displaying a state of charge of a rechargeable battery unit included in the display device.
