Abstract

A connection method for wireless display is provided. The connection method includes: activating by a mobile device an application program; acquiring by the mobile device a two-dimensional barcode image; 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 obtain a WiFi MAC address; determining by the mobile device whether the format of the WiFi MAC address is correct, if so, 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 with the WiFi display module via the WiFi MAC address; performing data transmission by the mobile device with the display device. By the above means, the present disclosure can effectively improve the connection efficiency between the mobile device and the display device and can thus greatly enhance the user experience.

First claim

2 . The connection method according to claim 1 , wherein the processing the two-dimensional barcode image to acquire the WiFi MAC address comprises:
applying binarization processing on the two-dimensional barcode image to acquire a plurality of binary values; searching for positioning symbols and correction symbols in the plurality of binary values; according to the positioning symbols and the correction symbols, performing image transformation on the plurality of binary values to generate a symbol code matrix; decoding the symbol code matrix conforming to coding standards, and acquiring parsed data comprising the WiFi MAC address when the decoding is completed.

3 . The connection method according to claim 1 , wherein the performing the data transmission by the mobile device with the display device comprises:
transmitting by the mobile device image data displayed on a screen of the mobile device to the display device, enabling the display device to display on its screen an image corresponding to the image data.

4 . The connection method according to claim 1 , wherein the performing the data transmission by the mobile device with the display device comprises:
acquiring, by the mobile device, image data displayed on the screen of the display device, and displaying on the screen of the mobile device an image corresponding to the image data.

5 . 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.

6 . The connection method according to claim 5 , further comprising:
when the two-dimensional barcode image is determined to be identical with the prestored image, acquiring the WiFi MAC address corresponding to the prestored image, and establishing a data connection by the WiFi display module with the display device via the WiFi MAC address.

7 . The connection method according to claim 5 , wherein the processing the two-dimensional barcode image to acquire the WiFi MAC address comprises:
applying binarization processing on the two-dimensional barcode image to acquire a plurality of binary values; searching for positioning symbols and correction symbols in the plurality of binary values; according to the positioning symbols and the correction symbols, performing image transformation on the plurality of binary values to generate a symbol code matrix; decoding the symbol code matrix conforming to coding standards, and acquiring parsed data comprising the WiFi MAC address when the decoding is completed.

8 . The connection method according to claim 5 , wherein the performing the data transmission by the mobile device with the display device comprises:
transmitting by the mobile device image data displayed on a screen of the mobile device to the display device, enabling the display device to display on its screen an image corresponding to the image data.

9 . The connection method according to claim 5 , wherein the performing the data transmission by the mobile device with the display device comprises:
acquiring, by the mobile device, image data displayed on the screen of the display device, and displaying on a screen of the mobile device an image corresponding to the image data.

10 . 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;
