receiving, by the display device in the customized mode, a push instruction for playing a media file transmitting from the mobile device via the monitor service, lighting the screen of the display device, and playing the media file according to the push instruction so as to make the display device enter the normal operating mode.

2. The method according to claim 1 , wherein the playing the media file according to the push instruction comprises:

acquiring, by the display device according to a local media file address of the mobile device contained in the push instruction, a local media file from the mobile device; and

playing, by the display device, the local media file.

3. The method according to claim 1 , wherein the playing the media file according to the push instruction comprises:

acquiring, by the display device according to a media file source address contained in the push instruction, an online media file from a network server corresponding to the media file source address; and

playing, by the display device, the online media file.

4. The method according to claim 3 , further comprising:

starting, by the display device upon entering the customized mode, the monitor service to monitor the push instruction transmitting from the mobile device.

5. The method according to claim 4 , further comprising:

shutting down, by the display device after receiving the push instruction transmitting from the mobile device, the monitor service.

6. The method according to claim 4 , further comprising:

determining, by the display device in the customized mode, whether the push instruction transmitting from the mobile device associated with the display device is received or not within a preset duration;

in response to not receiving the push instruction within the preset duration, making the display device enter the standby mode, and keeping the wireless module on in the standby mode.

7. The method according to claim 3 , further comprising:

setting, by the display device upon entering the customized mode, the display device in audio mute.

8. The method according to claim 7 , further comprising:

cancelling, by the display device after receiving the push instruction, the audio mute.

9. The method according to claim 8 , further comprising:

directly playing, by the display device after lighting the screen of the display device, the media file according to the push instruction, without playing a boot animation.

10. A display device for playing a media file, comprising:

a memory storing instructions;

a wireless module;

a power manager module; and

a processor in communication with the memory, wherein, when the processor executes the instructions, the processor is configured to cause the display device to:

while the display device is in a standby mode, receive a wakeup signal broadcasted from a mobile device through the wireless module in the display device, wherein the display device is configured to have the standby mode, a customized mode different from the standby mode, and a normal operating mode;

trigger an electrical level change according to the wakeup signal, to cause the display device to enter into the customized mode where the display device is started but a screen of the display device is not lighted and a monitor service is started additionally with respect to the standby mode, wherein the display device in the customized mode is discoverable by the mobile device so as to associate the display device with the mobile device, and the electrical level change is triggered by pulling down a level of a universal output/input interface connected with the power manager module by the wireless module; and

while the display device is in the customized mode, receive a push instruction for playing a media file transmitting from the mobile device via the monitor service, light the screen of the display device, and play the media file according to the push instruction so as to make the display device enter the normal operating mode.

11. The display device according to claim 10 , wherein, when the processor is configured to cause the display device to play the media file according to the push instruction, the processor is configured to cause the display device to:

acquire, according to a mobile device local media file address contained in the push instruction, a local media file from the mobile device; and

play the local media file.

12. The display device according to claim 10 , wherein, when the processor executes the instructions, the processor is configured to further cause the display device to:

upon entering the customized mode, start the monitor service to monitor the push instruction transmitting from the mobile device.

13. The display device according to claim 12 , wherein, when the processor executes the instructions, the processor is configured to further cause the display device to:

shut down the monitor service after receiving the push instruction transmitting from the mobile device.

14. The display device according to claim 12 , wherein, when the processor executes the instructions, the processor is configured to further cause the display device to:

during the customized mode, determine whether the push instruction transmitting from the mobile device associated with the display device is received or not within a preset duration; and

in response to not receiving the push instruction within the preset duration, make the display device enter the standby mode, and keep the wireless module power on in the standby mode.

15. The display device according to claim 10 , wherein, when the processor is configured to cause the display device to play the media file according to the push instruction, the processor is configured to cause the display device to:

acquire, according to a media file source address contained in the push instruction, an online media file from a network server corresponding to the media file source address; and

play the online media file.

16. The display device according to claim 15 , wherein, when the processor executes the instructions, the processor is configured to further cause the display device to:

upon entering the customized mode, set the display device in audio mute.

17. The display device according to claim 16 , wherein, when the processor executes the instructions, the processor is configured to further cause the display device to:

cancel the audio mute after receiving the push instruction transmitting from the mobile device.

18. The display device according to claim 17 , wherein, when the processor executes the instructions, the processor is configured to further cause the display device to:

after the screen of the display device is lighted, directly play the media file according to the push instruction, without playing a boot animation.
