Display methods can be applied on mobile terminal, which can include but is not limited to smart mobile phone and tablet computer
(PAD), which includes step：
Step S101, the end message and content to be displayed for being used to implement multi-screen tiled display are obtained；
Wherein, end message includes at least：Terminal quantity and each terminal positional information (such as location coordinate information).
It should be noted that the terminal for being used to implement multi-screen tiled display is generally rectangular, and therefore, the position of these terminals
Confidence breath can use top left co-ordinate and lower right corner coordinate representation, such as (0.5*width, 0, width, 0.5*height), wherein,
(0.5*width, 0) represents the top left co-ordinate of terminal, and (width, 0.5*height) represents the bottom right angular coordinate of terminal.
In the present embodiment, the terminal for being used to implement multi-screen tiled display is a including N (N >=2), can in this N number of terminal
To include control terminal, i.e. control terminal also assists in display content to be displayed；In addition, control can not also be included in this N number of terminal
Terminal processed needs another terminal as control terminal.
Wherein, control terminal is as source device (WFD Source) is shown, for the content to be displayed in the equipment to be thrown
It is mapped to other-end.
Terminal other than control terminal with equipment (WFD Sink), is passed as display for receiving control terminal by WiFi
The content to be displayed sent, and other-end is cooperateed with to combine content to be displayed and is shown.
The English full name of WFD is：WiFi-Direct, WiFi-Direct are a kind of completely new technologies, even if not passing

Terminal in order to control.
Step S102, content to be displayed is split according to end message, obtains end message and correspond to treating for each terminal
Display segmentation content；
The native system of terminal as display equipment uses Android WiFi Display structure systems, only supports
One Display (display), i.e. display equipment.In Android WiFi Display structure systems, Remote
Display (remote display) is obtained by Surface (surface layer) objects from Surface Flinger (display synthesis system) module
The image that upper strata UI (user interface) is taken to be drawn, and Surface objects are really from Surface Media Source (face matchmakers
Body source) it obtains, therefore, content to be displayed need to pass through Surface Media Source:：Read functions obtain.
Since display equipment is extended to from 1 N number of, and show that source device is still one, therefore, each display is read with equipment
The object taken is constant, but the content read becomes smaller, i.e., each display equipment only reads corresponding segmentation content to be shown.
Wherein, the specific implementation process of step S102 is as follows：
The arrangement N=ColN*LineM of N number of identical display equipment, wherein, ColN represents Nth column, and LineM represents the
M rows, referring specifically to table 1：

Since terminal 201 is according to the end message of terminal 202-205, content to be displayed is split to obtain terminal 202-205
Segmentation content to be shown, and terminal 201 without display, therefore, terminal 201 need to terminal 202-205 send it is corresponding
Segmentation content to be shown.
When the terminal for being used to implement multi-screen tiled display includes present terminal, i.e. control terminal, due to control terminal
According to end message, content to be displayed is split to obtain each segmentation content to be shown, and control terminal shows and treats
Display segmentation content, therefore, the terminal transmission that control terminal need to be used to implement multi-screen tiled display to other-end are corresponding
Segmentation content to be shown.
