When the wired interface 17 is disconnected from the external device 25, the processing device 15 stops obtaining and processing the first display data, and the third transmission device 13 maintains the wireless connection with the second electronic device 22 and stops transmitting the second display data.

If the second transmission device 12 and the battery device 16 are connected in parallel and then connected to the processing device 15, the power supply priority of the power supply equipment 23 is higher than the power supply priority of the battery device 16. When the transmission device 100 can supply the electric energy through the power supply device 23, the battery device 16 does not output the electric energy, and at this time, if the electric energy of the battery device 16 is insufficient, the electric energy can be stored while the transmission device 100 is supplied with the electric energy through the power supply device 23, so that the transmission device 100 is supplied with the electric energy after the transmission device 100 is disconnected from the power supply device 23. When the transmission device 100 is disconnected from the power supply device 23, the transmission device 100 is supplied with power through the battery device 16.

For the first electronic device 21 that cannot provide the power supply function, the screen projector cannot be used. The transmission device 100 according to the embodiment of the present application can supply power through the built-in battery device 16, and for the first electronic device 21 that cannot provide a power supply function, the first electronic device 21 may not need to be supplied with power, and the second electronic device 22 may be provided with power through the built-in battery device 16 to perform screen projection display. For example, for the first electronic device 21 that cannot provide power supply function, such as a mobile phone, the transmission device 100 can realize the screen projection display of the display data in the first electronic device 21 on the second electronic device 22 during the power supply time of the battery device 16.

In the embodiment of the present application, when the first electronic device 21 is replaced, the transmission device 100 may be powered by the built-in battery device 16, and in the replacement process, the transmission device 100 system maintains continuous operation by powering the built-in battery device 16, maintains the wireless connection with the second electronic device 22, does not need system initialization, and does not need a search and authentication process required to reestablish the wireless connection with the second electronic device.
When power is supplied by the battery device 16, the influence of unstable power of the external power supply device 23 on the display data transmission can be reduced, at this time, the power of the external power supply device 23 can only influence the charging of the battery device 16, and the hardware working state in the transmission device 100 is ensured by the battery device 16 to be stable.
