Embodiment 1
[0084] image 3 It is a flowchart of the first embodiment of the control method for screen-off and screen-casting according to the present invention. A control method for screen-off and screen-casting, the method includes:
[0085] S1. During the screen projection creation stage, if the screen-off projection instruction is received, the screen-off projection state is entered; if the screen-off projection instruction is not received, the bright-screen projection state is entered;
[0086] S2. In the off-screen projection state, if a bright-screen instruction is received, switch from the off-screen projection state to the bright-screen projection state;
[0087] S3. In the bright-screen projection state, if a screen-off instruction is received, switch from the bright-screen projection state to the off-screen projection state;
[0088] S4. In the off-screen projection state or the bright-screen projection state, if a stop projection instruction is received, the current projecti...
Embodiment 2
[0092] Figure 4 This is a flowchart of the second embodiment of the screen-off screen projection control method of the present invention. Based on the above-mentioned embodiments, in the screen projection creation stage, if a screen-off-screen projection instruction is received, the screen-off projection state will be entered. When the screen-off-screen projection command is reached, the screen-on-screen projection state is entered, including:
[0093] S11. In the projection screen creation stage, generate a first option for screen projection without screen;
[0094] S12. Monitor the open state of the first option, and if the first option is switched from the closed state to the open state, generate an off-screen projection instruction, and enter the off-screen projection state;
[0095] S13. If the off state of the first option does not change within the first preset operation time limit, enter the bright screen projection state.
[0096] In this embodiment, first, in the ...
Embodiment 3
[0101] Figure 5 This is a flowchart of the third embodiment of the screen-off-screen projection control method of the present invention. Based on the above embodiments, in the off-screen projection state, if a bright-screen instruction is received, the off-screen projection state Switching to the bright screen projection state includes:
[0102] S21. In the screen-off-screen projection state, generate a second option for bright-screen projection;
[0103] S22. Detect the on state of the second option, and if the second option is switched from the off state to the on state, switch from the off-screen projection state to the bright-screen projection state;
[0104] S23. If the closed state of the second option does not change within the second preset operation time limit, keep the screen-off and screen-casting state.
[0105]In this embodiment, first, in the off-screen projection state, a second option for bright-screen projection is generated; then, the ON state of the secon...
