Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed description will be omitted.
Referring to fig. 1, fig. 1 is a flowchart of a screen projection method of a mobile device in this embodiment. The screen projection method comprises the following steps:
step S110: a wired connection is established between the mobile device and the display device.
The mobile device can be a mobile terminal such as a mobile phone and a tablet computer. The display device includes a display screen. The display device serves as a peripheral for the mobile device, and the display device may have no memory function. The display device may be an integrated device integrating an input component and a display screen, wherein the input component may be a keyboard and/or a mouse. The display device may also be a display or a smart television.
The wired connection between the mobile device and the display device may be interconnected through a common physical interface, such as a USB interface, a DisplayPort interface or a SmartPort interface up to door technology. Preferably, the display device is provided with a keyboard, a connection area is arranged on the keyboard, an interface of the display device is arranged in the connection area, and the interface is a magnetic suction interface. After the setting, the wired connection can be established between the mobile equipment and the display equipment only by placing the mobile equipment in the connection area and adsorbing the corresponding interface on the mobile equipment by the magnetic suction interface; when the mobile device needs to be taken, the mobile device only needs to be directly taken up from the connection area, so that the mobile device is more convenient to take and place, and the user experience is improved.
Step S120: the mobile device sends the screen projection data to the display device through the wired connection to display the screen projection picture on the display device.
After the mobile device detects that the wired connection between the mobile device and the display device is connected, the mobile device sends screen projection data to the display device through the wired connection, and the display device displays screen projection pictures on the display device after receiving the screen projection data. The screen projection data sent by the mobile device can be picture, character or video data, and the display device can respectively display corresponding pictures, characters or video pictures on the display screen after acquiring the video data. The advantage of the mobile device projecting the picture on the display device through the wired connection is low delay, stable picture and fast transmission speed.
Step S130: the wired disconnection information is obtained when the wired connection between the mobile device and the display device is disconnected.
The wired connection between the mobile device and the display device is disconnected when the operator needs to use the mobile device temporarily or leave the display device temporarily to take the mobile device away. For example, when the mobile device is a cell phone, the operator answers the phone to remove the mobile device from the interface of the display device.
After the wired connection is established, the mobile device detects whether the wired connection between the mobile device and the display device is disconnected in real time, and if the disconnection between the mobile device and the display device is detected, the wired connection disconnection information is obtained. The display equipment sends heartbeat signals to the mobile equipment through wired connection at regular intervals, and the fact that the mobile equipment does not receive the heartbeat signals within a preset time period indicates that the wired connection between the mobile equipment and the display equipment is disconnected.
Step S140: the mobile device transmits screen projection data to the display device through a wireless connection established with the display device in response to the wired connection disconnection information to display a screen projection screen on the display device.
The mobile device and the display device can be connected wirelessly, and when the mobile device and the display device both support the same direct connection screen projection protocol, screen projection data on the mobile device can be transmitted to the display device and played on the display device. The direct connection screen projection protocol may be Miracast or widi (intel Wireless display). WiDi is a wireless high-definition technology, and realizes wireless connection between two terminals through WiFi signals. Miracast is a wireless display standard based on Wi-Fi Direct (Wi-Fi Direct), and devices supporting Miracast can rapidly transmit videos among the devices.
The mobile device and the display device can also be added into the same wireless local area network, and the mobile device sends screen projection data to the display device through the wireless local area network. Both the mobile device and the display device support the same LAN screen projection protocol, such as Airplay or DLNA (DIGITAL LIVING NETWORK ALLIANCE).
The wireless connection can also adopt wireless connection technologies such as Bluetooth wireless transmission, infrared transmission and the like.
After detecting that the wired connection between the mobile device and the display device is disconnected, the mobile device sends the screen projection data to the display device through the wireless connection between the mobile device and the display device so as to continuously display the screen projection picture on the display device.
When the mobile device is used for screen projection, screen projection data is transmitted to the display device through wired connection for screen projection, and a picture is displayed with high quality. If the wired connection needs to be disconnected temporarily in the midway of using the display equipment, the mobile equipment automatically switches to the transmission of screen projection data through the wireless connection with the display equipment, and the picture can be continuously displayed on the display equipment after the wired connection is disconnected temporarily, so that the use is more convenient, and the user experience is improved.
Further, referring to fig. 2, the screen projection method further includes step S150 and step S160.
Step S150 is performed after step S110 and before step S130. Step S150: the mobile device receives wireless screen projection information sent by the display device through wired connection.
The wireless screen projection information sent by the display device can be automatically sent by the display device or sent by the display device at the request of the mobile device. For example, the display device actively sends the wireless screen projection information to the mobile device through the limited connection after detecting that the wired connection is established with the mobile device. For example, after detecting that a wired connection is established with the display device, the mobile device sends a request for acquiring wireless screen projection information to the display device through the wired connection, and after receiving the request, the display device sends the wireless screen projection information to the mobile device through the wired connection.
The wireless screen projection information includes device identification information. The device identification information is used to identify the identity of the display device. The device identification information may be a MAC Address (Media Access Control Address) or a name of the display device.
Step S160 is performed after step S150. Step S160: and searching the display equipment according to the wireless screen projection information and establishing wireless connection with the display equipment.
The step of establishing wireless direct connection between the mobile device and the display device comprises the following steps: after the mobile device receives the wireless screen projection information, searching for devices capable of establishing wireless direct connection with the mobile device, judging whether the searched devices have devices with the same names as the device identification information in the wireless screen projection information, and if yes, establishing wireless connection with the devices.
The wireless screen projection information also comprises wireless local area network information, and the wireless local area network information is used for indicating the wireless local area network where the display equipment is located.
The step of establishing a wireless local area network connection between the mobile device and the display device comprises: after receiving the wireless screen projection information, the mobile device searches and enters a wireless local area network corresponding to the wireless local area network information, then finds the display device in the wireless local area network according to the device identification information and establishes connection, wherein the device identification information can be an MAC address.
Therefore, wireless connection can be automatically established between the mobile equipment and the display equipment, and the operation personnel can use the mobile equipment more conveniently.
Further, step S160 may be implemented after step S130. The wireless connection between the mobile device and the display device may be established after the wired connection is broken. In step S160, the mobile device establishes a wireless connection upon detecting disconnection of the wired connection.
At the moment of disconnection of the wired connection, the mobile device detects the disconnection of the wired connection, immediately establishes a wireless connection, and then continues to transmit screen projection data through the wireless connection. The wireless connection is established only when the wired connection is disconnected, so that the electric energy consumption caused by continuously keeping the wireless connection is avoided, and the electric quantity and hardware resources of the mobile equipment can be saved.
Step S160 may also be performed before step S130, before the wired connection between the mobile device and the display device is disconnected. In step S160, the wireless connection is established immediately after the wired connection is established.
Due to the fact that the wireless connection is established in advance, the screen projection data can be immediately sent to the display device through the wireless connection after the wired connection is disconnected, connection is seamlessly switched, the wireless connection does not need to be established temporarily, and pictures displayed on the display device are more stable and smooth when the data transmission mode is switched.
Further, the screen projection method further includes step S170 and step S180, wherein step S170 is implemented after step S140, and step S180 is implemented after step S170.
Step S170: when the mobile device sends screen projection data to the display device through wireless connection, if the distance between the mobile device and the display device is larger than a preset threshold value, the mobile device stops sending the screen projection data, and sends a standby instruction for switching the display device to a standby mode to the display device through wireless connection.
The preset threshold is preferably less than a maximum communication distance of the wireless connection between the mobile device and the display device. The value range of the preset threshold value can be 1.5-4 m. The mobile device may be mounted with a wireless communication module capable of detecting a communication distance to acquire a distance between the mobile device and the display device. The mobile equipment can also be provided with a first positioning device for detecting the position of the mobile equipment, the display equipment is provided with a second positioning device for detecting the position of the display equipment, the position information acquired by the second positioning device is sent to the mobile equipment, and the mobile equipment can calculate the distance between the mobile equipment and the display equipment according to the positions acquired by the first positioning device and the second positioning device.
Step S180: and if the display equipment is detected to be in the standby mode and the distance between the mobile equipment and the display equipment is recovered to be within the preset threshold value, the mobile equipment sends a wake-up instruction for switching the display equipment to the working mode to the display equipment through wireless connection, and continues to send screen projection data to the display equipment.
When the operator takes the mobile device away and leaves the display device, and the distance between the mobile device and the display device is larger than a preset threshold value, the display device is automatically switched to a standby mode to save electric energy. When the distance from the mobile equipment to the display equipment is smaller than the preset threshold value, the display equipment is automatically awakened again, the display equipment does not need to be artificially awakened again, and the mobile display equipment is more convenient to use.
Further, the screen projection method further includes a step S190 after the step S150 and a step S200 after the steps S160 and S190.
Step S190: and the mobile equipment stores the wireless screen projection information after acquiring the wireless screen projection information.
Step S200: and if the wireless connection is disconnected, the mobile equipment establishes wireless connection with the display equipment again according to the wireless screen projection information.
After the wireless connection is disconnected, the mobile device can automatically search the display device again according to the wireless screen projection information stored in the mobile device, and after the display device is searched, the mobile device is wirelessly connected with the display device.
Even if the wireless connection between the mobile device and the display device is accidentally disconnected, the wireless connection between the mobile device and the display device can be quickly reestablished.
After the operator goes out to take the mobile device away, the distance between the mobile device and the display device exceeds the maximum communication distance of wireless connection, the wireless connection between the mobile device and the display device is disconnected, and when the operator returns to the vicinity of the mobile device, the mobile device can automatically establish wireless connection with the display device.
Further, step S110 further includes clearing, by the mobile device, the wireless screen projection information stored before the wired connection is established and disconnecting the wireless connection established before the wired connection is established when the wired connection is established.
In this way, after each wired connection is established between the mobile device and one display device, the information left after the wired connection with other display devices is established before is cleared, and meanwhile, the wireless connection established with other display devices is disconnected.
Further, the mobile device sends the screen projection data to the display device only through the wired connection when both the wired connection and the wireless connection exist.
Therefore, the electric energy of the mobile equipment can be saved, and meanwhile, high-quality pictures are displayed on the display equipment.
Furthermore, the mobile device can receive the electric energy input by the display device when establishing the wired connection with the display device. Therefore, the mobile equipment can be charged while the screen is projected.
Furthermore, the mobile device can run at least two operating systems simultaneously, and the interface of one of the operating systems is projected to the display device for display, that is, the screen projection picture is the operating interface of one of the operating systems. For example, two Android operating systems are run on the mobile device, and an interface of one of the Android operating systems is projected to the display device; or, running an Android operating system and a Windows operating system on the mobile device, and projecting the interface of the Windows operating system to the display device.
The real-time picture of the interface of the operating system is used as a video source, the video source is sent to the display device in the form of video stream so as to display the interface of the operating system on the display device in real time, and the other interface of the operating system can be displayed on the screen of the mobile device. The mobile device and the display device can display the interfaces of two different operating systems, so that the content of the interface displayed by the mobile device and the content of the interface displayed by the display device can be compared more conveniently.
