Method for connecting screen mirroring device based on two-dimensional code

Abstract

The invention discloses a method for connecting a screen mirroring device based on a two-dimensional code. The method comprises the following steps: firstly, connecting the screen mirroring device with a display device comprising a display screen through a HDMI data line; secondly, generating one two-dimensional code on the display screen of the display device through a two-dimensional code generation system, wherein the two-dimensional code acquires device information of the screen mirroring device at the same time; then, scanning the generated two-dimensional code through a mobile terminal,and realizing wireless connection between a mobile terminal device and the screen mirroring device; and finally, projecting information on the screen of the mobile terminal to the display screen of the display device. According to the method provided by the invention, by scanning the two-dimensional code on a display, one-key connection between the mobile terminal and the screen mirroring device is realized, a content on the mobile terminal is projected on the display for being displayed, change of displaying from a small screen to a big screen is realized, and better visual experience can bebrought to users; and with the method provided by the invention, steps of use of the conventional screen mirroring device can be simple and clear, and the mobile terminal can be quickly connected withthe screen mirroring device.

Description

Technical field: [0001] The invention relates to the technical field of wireless co-screening, in particular to a method for connecting a co-screening device based on a two-dimensional code. Background technique: [0002] The wireless screen sharer is a kind of file that can transfer video, audio, pictures and other files in the mobile device to another playback device through the wireless network. When in use, connect the output interface of the same-screen transmitter with the input interface of the device to be displayed (for example, using an HDMI interface). The transmitter should come with an APP. Plug the display device into the display device (such as computer, TV, etc.). Open the phone settings--display--wireless display, search for the device, and connect to the same screen. The same screen device has been widely used in people's home and work. [0003] The use steps of the traditional wireless same-screen technology are complicated, and each time you use it, y...

AI Technical Summary

Problems solved by technology

[0003] The use steps of the traditional wireless same-screen technology are complicated, and each time you use it, you need to perform steps such as setting, searching, and connecting, and the operation is relatively cumbersome

It is not easy to use, and the user experience is not ideal, which leads to the failure of the screen sharing device to be widely used in life
