Connection method and mobile device for wireless display

A connection method for wireless display, comprising:

• activating, by a mobile device, an application program, wherein a camera of the mobile device is turned on concurrently when the application program is activated;
• scanning, by the mobile device via the camera, a two-dimensional barcode image displayed on a screen of a display device and thus acquiring the two-dimensional barcode image, wherein the two-dimensional barcode image is recorded with a WiFi MAC address of the display device;
• determining by the mobile device whether the two-dimensional barcode image is identical with a prestored image, if not, processing the two-dimensional barcode image to acquire the WiFi MAC address;
• further determining by the mobile device whether a format of the WiFi MAC address is correct, when it is correct, storing the two-dimensional barcode image and its corresponding WiFi MAC address;
• broadcasting by the mobile device the WiFi MAC address to a WiFi display module of the mobile device, and establishing a data connection by the WiFi display module with the display device via the WiFi MAC address;
• and
• performing data transmission by the mobile device with the display device.

A mobile device, comprising:

• a processor;
• and
• a non-transitory program storage medium, comprising:
• an application program module, configured to activate an application program, wherein a camera of the mobile device is turned on concurrently when the application program is activated;
• an image acquisition module connected to the application program module, being configured to scan via the camera a two-dimensional barcode image displayed on a screen of a display device and thus acquire the two-dimensional barcode image, wherein the two-dimensional barcode image is recorded with a WiFi MAC address of the display device;
• an image determination module connected to the image acquisition module, being configured to determine whether the two-dimensional barcode image is identical with a prestored image;
• an address acquisition module connected to the image determination module, being configured to, when the image determination module determines that the two-dimensional barcode image is not identical with the prestored image, process the two-dimensional barcode image to acquire the WiFi MAC address;
• an address format determination module connected to the address acquisition module, being configured to determine whether a format of the WiFi MAC address is correct;
• a storage module connected to the address format determination module, being configured to, when the address format determination module determines that the format of the WiFi MAC address is correct, store the two-dimensional barcode image and its corresponding WiFi MAC address;
• a data broadcasting module connected to the storage module, being configured to broadcast the WiFi MAC address to a WiFi display module of the mobile device;
• the WiFi display module, which is connected to the data broadcasting module, being configured to establish a data connection with the display device via the WiFi MAC address;
• and
• a data transmission module connected to the WiFi display module, being configured to, when the WiFi display module completes the data connection with the display device via the WiFi MAC address, perform data transmission between the mobile device and the display device.
