On end；
When mobile terminal leaves blank induction range, blank disconnects and the link of mobile terminal, and on automatic trial division blank
The content of display；
There is mobile terminal in induction range when blank senses again, blank and mobile terminal establish the link again；Blank
The content of the last content saved and Historic preservation that save on mobile terminal is got, the selected last preservation of blank
Inside perhaps select the content of Historic preservation；
The content that blank selects is sent to blank by mobile terminal, and is shown on blank.
For improvement of the invention, before the blank and mobile terminal establish the link further include: blank is encrypted,
It is described that the link that encryption is applied to blank and mobile terminal is carried out to blank, and the content of the display of preservation is existed again
It is shown on electronic whiteboard.
It further include preset threshold for improvement of the invention, when the threshold values that blank and mobile terminal link is less than described pre-
If when threshold values, uploading instructions are triggered, by the content uploading shown on blank to mobile terminal.
For improvement of the invention, it is with text that the content that will be shown on blank by NFC, which is saved on mobile terminal,
The form of shelves or picture is saved on mobile terminal.
The present invention also provides a kind of blank, the blank includes display module and the first NFC chip, and the display module is used
In the content that display is written on the display module, first NFC chip is used to incude the mobile terminal in blank induction range,
And the data transmission between mobile terminal, the blank further include:
Link module, for being linked with the mobile terminal in blank induction range；
Uploading module, for by the content uploading shown on display module to mobile terminal；
Trial division module, for after by the content uploading to mobile terminal shown on display module, by the display module
The content of upper display trial division on the display module；
Receiving module, after blank senses again has mobile terminal in blank induction range, the receiving module is used for
Receive the content of the display saved on mobile terminal；
Processing module, for being shown after the content for receiving the display on the display module.
For improvement of the invention, the blank further includes encrypting module, for the connection of blank and mobile terminal, and
For by the content uploading of the display saved on mobile terminal to electronic whiteboard.
The present invention also provides a kind of mobile terminal, the mobile terminal includes:
