Linked display system and linked display method

A linked display system comprising:

• a first information device;
• and
• a second information device,
• the first information device and the second information device being connected so as to communicate with each other,
• the first information device including a first display, a first communication device configured to transmit and receive data to and from the second information device, and a first processor configured to control the first display and the first communication device,
• the second information device including a second display, a second communication device configured to transmit and receive data to and from the first information device, and a second processor configured to control the second display and the second communication device,
• the first information device having a normal mode and a first linkage power saving mode, the normal mode being for turning on a screen display of the first display and maintaining device-to-device communication with the second information device, and the first linkage power saving mode being for turning off the screen display of the first display when no operation is performed on the first information device for a predetermined period of time or longer,
• the first information device being configured to:
• upon start of a linked operation between the first information device and the second information device, enable the first linkage power saving mode of the first information device;
• transmit second divided data including a part of data for display to be shown on the first display to the second information device;
• show, on the first display, first divided data that remains after the second divided data is cut out from the data for display;
• and
• while the screen display of the first display is being turned off, upon receiving a trigger signal for turning on the screen display, turn on the screen display of the first display, and
• the second information device being configured to, upon receiving the second divided data, show the second divided data on the second display.

A linked display system comprising:

• a first information device;
• and
• a second information device,
• the first information device and the second information device being connected so as to communicate with each other,
• the first information device including a first display, a first communication device configured to transmit and receive data to and from the second information device, and a first processor configured to control the first display and the first communication device,
• the second information device including a second display, a second communication device configured to transmit and receive data to and from the first information device, and a second processor configured to control the second display and the second communication device,
• the first information device having a normal mode and a second linkage power saving mode, the normal mode being for turning on a screen display of the first display and maintaining device-to-device communication with the second information device, and the second linkage power saving mode being for constantly turning on the first display and turning off other predetermined functions so as to operate with less power consumption than that in the normal mode,
• the first information device being configured to:
• upon start of a linked operation between the first information device and the second information device, switch a mode of the first information device to the second linkage power saving mode;
• transmit second divided data including a part of data for display to be shown on the first display to the second information device;
• and
• show, on the first display, first divided data that remains after the second divided data is cut out from the data for display, and
• the second information device being configured to, upon receiving the second divided data, show the second divided data on the second display.

A linked display method to be executed by a first information device and a second information device which are connected so as to communicate with each other, the method comprising:

• starting a linked operation between the first information device and the second information device;
• disabling a power saving mode of the first information device to switch a screen display of a first display provided in the first information device to be constantly turned on;
• transmitting second divided data including a part of data for display to be shown on the first display to the second information device;
• showing, on the first display, first divided data that remains after the second divided data is cut out from the data for display;
• by the second information device, receiving the second divided data;
• and
• by the second information device, showing the second divided data on a second display provided in the second information device.
