## Abstract

Disclosed is a display device for sharing one virtual screen image with other display devices, comprising display means for displaying a physical screen image corresponding to a portion of the virtual screen image; computing means for executing computations of the display device; and communication means for communicating with other display devices, so that those display devices are capable of interacting with each other via the virtual screen image.

## Claims

### Claim 1

A display device for sharing one virtual screen image with other display devices, comprising:
display means for displaying a physical screen image corresponding to a portion of the virtual screen image;
computing means, connected with the display means, for executing computations of the display device; and
communication means, connected with the computing means, for communicating with other display devices to share the virtual screen image.

### Claim 2 (depends on 1)

The display device as claimed in claim 1, wherein the communication means is communicated with other display devices by a wireless transmission method.

### Claim 3 (depends on 1)

The display device as claimed in claim 1, wherein the communication means is communicated with other display devices via a physical transmission line.

### Claim 4 (depends on 1)

The display device as claimed in claim 1, wherein the communication means is communicated with other display devices through a network.

### Claim 5 (depends on 1)

The display device as claimed in claim 1, wherein the virtual screen image is sourced from the physical screen image selected from one of the display device and other display devices.

### Claim 6 (depends on 5)

The display device as claimed in claim 5, wherein the virtual screen image is obtained by resizing the physical screen image.

### Claim 7 (depends on 5)

The display device as claimed in claim 5, wherein the virtual screen image is obtained by changing the image resolution of the physical screen image.

### Claim 8 (depends on 1)

The display device as claimed in claim 1, wherein the portion of the virtual screen image corresponding to the physical screen image is associated with the position of the display device in relation to all of the display devices sharing the virtual screen image.

### Claim 9 (depends on 1)

The display device as claimed in claim 1, wherein the physical screen image of the display device is data/files transmittable to the physical screen image of other display devices through the virtual screen image.

### Claim 10 (depends on 1)

The display device as claimed in claim 1, further comprising determining means, connected with the computing means, for determining whether sharing the virtual screen image with other display devices.
