the first preset threshold is used for representing the maximum number of screen projection sources which can be connected with the screen projection equipment, and the second preset threshold is used for representing the maximum number of windows which can be opened on the screen projection equipment.

11. The method according to claim 10, wherein the displaying, in at least one of the target windows, screen projection information projected by the second target screen projection source to the screen projection device according to the obtained disconnection instruction includes:

and according to the obtained disconnection instruction, taking a target window as a display window of a newly connected second target screen projection source, and displaying screen projection information projected to the screen projection equipment by the second target screen projection source through the display window, wherein the disconnection instruction indicates that the connection between a first target screen projection source and the screen projection equipment is disconnected, and the screen projection information projected to the screen projection equipment by the first target screen projection source is displayed on the display window.

12. The method according to claim 10, wherein the displaying, in at least one of the target windows, screen projection information projected by the second target screen projection source to the screen projection device according to the obtained disconnection instruction includes:

determining at least one target window according to the acquired connection breaking instruction and at least one of a target window with a focus in each target window, a prompt of each target window and a preset selection frame;

and displaying screen projection information projected to the screen projection equipment by the second target screen projection source in the at least one target window.

13. A screen projection apparatus, comprising:

the first processing module is used for acquiring a disconnection instruction;

the second processing module is used for disconnecting the connection between at least one first target screen projection source and the screen projection equipment according to the connection disconnection instruction and determining a second connection number, wherein the second connection number is the number of the first target screen projection sources which are not disconnected;

the third processing module is used for displaying screen projection information projected to the screen projection equipment by each first target screen projection source which is not disconnected according to the second connection number and the first window number, wherein the first window number is the number of target windows opened on the screen projection equipment;

14. A screen projection apparatus, comprising:

the fourth processing module is used for acquiring a first connection opening instruction triggered by a screen projection source and a window opening instruction triggered by a user terminal, wherein the first connection opening instruction is used for indicating the screen projection device to be connected with the screen projection source, and the window opening instruction is used for indicating the opening of a window on the screen projection device;

the fifth processing module is used for receiving window display instructions and displaying screen projection information projected to the screen projection equipment by each first target screen projection source by using each target window;

15. An electronic device, comprising: a processor, a memory;

the memory for storing a computer program;

the processor is used for executing the screen projection method of any one of the claims 1-12 by calling the computer program.

16. A computer-readable medium, in which a computer program is stored which, when being executed by a processor, is adapted to carry out a screen projection method according to any one of claims 1 to 12.
