In the embodiment of the present application, when in the extended mode, the data on the host needs to be displayed jointly through all the display screens. At the moment, the number N of the display screens is calculated, then the data on the host are equally divided into N parts, then the N parts of data are jointly displayed through the N display screens, the data displayed on each display screen are different, and the data displayed on all the display screens jointly form the data of the host. And then judging the display mode of each display screen, and displaying the data on the corresponding display screen according to the display mode.
In this embodiment of the present application, the displaying the corresponding data on the corresponding display screen according to the display mode includes:
judging whether the display screen is in a transverse mode or not;
if yes, corresponding data are transversely displayed on the corresponding display screen;
and if not, longitudinally displaying the corresponding data on the corresponding display screen.
In the embodiment of the present application, specifically, the display mode is a landscape mode or a portrait mode. When the mode is the horizontal mode, the display screen displays data in the horizontal mode; when the mode is the portrait mode, the display screen displays data in the portrait mode.
