The screen projection method includes acquiring screen interface content data corresponding to first operation interfaces if operating system switching commands are received when contents on the first screen interfaces are projected onto target receiving screens by first operating systems, and transmitting the screen interface content data to the target receiving screens; executing the operating system switching commands to switch the first operating systems of the terminal into second operating systems; enabling the target receiving screens to display the contents on the first screen interfaces of the first operating systems under the control according to the received screen interface content data. According to the technical scheme, the terminal, the screen projection method and the screen projection device have the advantages that interruption of screen projection due to operating system switching can be prevented, and accordingly the use experience can be improved for users.
Description
Technical field
The present invention relates to field of terminal technology, in particular to screen prjection device and a kind of terminal of a kind of screen prjection method of terminal, a kind of terminal.
Background technology
At present, when an operating system in multisystem terminal carries out screen prjection, switch if now there is operating system, so the content of screen prjection will switch or occur screen prjection interruption along with the switching of terminal operating system.
The defect of prior art is:
1) content of screen prjection switches along with the switching of terminal system or interrupts projection, the continuity that this situation does not utilize user to use terminal screen to project, because likely user is when switched system, do not want the screen prjection stopping terminal, just hope to be switched in another system and go to process some things, such as take a picture, send short messages etc., also likely user together with other users in the content of viewing screen prjection, keep the demand of intelligent multi-screen so just have in the process switched in multisystem.
2) if in multisystem handoff procedure, there occurs screen prjection and switch along with systematic evaluation or interrupt, so also just do not give play to the advantage of multisystem.Multisystem can individually be run, thus the process of a system cloud gray model be can not run by another system process interference.
Therefore a kind of new technical scheme is needed, operating system can be avoided to switch the interruption causing screen prjection, user can realize the Projection Display of different content on the display screen by the many projection terminal of multisystem, meet the user demand of user, improves user's experience.
Summary of the invention
The present invention is just based on the problems referred to above, propose a kind of new technical scheme, operating system can be avoided to switch the interruption causing screen prjection, user can realize the Projection Display of different content on the display screen by the many projection terminal of multisystem, meet the user demand of user, improve user's experience.
