Abstract

A multi-screen display system has a plurality of closely arranged display devices. A master device that is one of the display devices has a detection unit which detects that any of the display devices in the multi-screen display system has become not able to perform display; and a display control unit that controls display operation of the individual display devices according to a display method associated with a position in the multi-screen display system of each display device detected by the detection unit.

Claims

1. A multi-screen display system having a plurality of display devices connected with each other, one of which comprises a master device that comprises:

a detection unit which detects that any one or more of slave devices, which comprise the display devices other than the master device, are not able to perform display; and

a display control unit that controls display operation of the individual display devices according to a display method associated with a position in the multi-screen display system of each slave device detected by the detection unit.

2. The multi-screen display system in accordance with claim 1, wherein:

the master device comprises a storage unit that stores a display method which is associated with a position of each slave device and employed when the slave device is not able to perform display; and

the display control unit retrieves the display method associated with the position of the slave device that is not able to perform display and controls the display operation of the individual display devices according to the retrieved display method.

3. The multi-screen display system in accordance with claim 1, wherein:

the detection unit sends a Nondisplay detection signal, which is utilized to detect each slave device that is not able to perform display, to the individual slave devices and detects each slave device that is not able to perform display based on responses from the slave devices.

4. A display method utilized in a multi-screen display system having a plurality of display devices connected with each other, the method comprising:

detecting, by a master device, that comprises one of the display devices, that any one or more of slave devices, which comprise the display devices other than the master device, are not able to perform display; and

controlling, by the master device, display operation of the individual display devices according to a display method associated with a position in the multi-screen display system of each detected slave device.
