## Abstract

A multi display apparatus includes a first display, a second display, a hinge to connect the first display and the second display to each other, and a controller to control operations of the first and second displays according to sensing information of an input pen including a sensor.

## Claims

### Claim 1

A multi display apparatus comprising:
a first display;
a second display;
a hinge to connect the first display and the second display to each other; and
a controller to control operations of the first and second displays according to sensing information of an input pen comprising a sensor.

### Claim 2 (depends on 1)

The multi display apparatus as claimed in claim 1, further comprising a communicator that communicates with the input pen,
wherein the controller receives a sensing signal that is sensed by the sensor through the communicator, and controls the operations of the first and second displays according to the sensing signal.

### Claim 3 (depends on 2)

The multi display apparatus as claimed in claim 2, wherein the sensor comprises:
a motion sensor to sense a motion of the input pen,
wherein, when a sensing signal that is sensed by the motion sensor is received from the input pen, the controller performs an operation corresponding to a motion of the input pen.

### Claim 4 (depends on 3)

The multi display apparatus as claimed in claim 3, wherein, when the input pen touches at least one of the first and second displays, the controller performs a different operation according to a tilt of the input pen with reference to a touch surface.

### Claim 5 (depends on 4)

The multi display apparatus as claimed in claim 4, wherein the controller further considers a tilt direction of the input pen and controls to perform a corresponding operation.

### Claim 6 (depends on 2)
