Mobile phone screen projection method

Abstract

The invention discloses a mobile phone screen projection method, which comprises the following steps: S1, setting a digital television and a mobile phone in the same local area network; S2, connecting a remote controller with the digital television in a Bluetooth pairing manner; S3, knocking a specified position of the remote controller by the mobile phone; S4, identifying a knocking action by the remote controller through SENSOR and triggering a non-directional impossible connection broadcast signal to the mobile phone; s5, receiving, by the mobile phone, the broadcast signals and judges whether the broadcast signals are screen projection broadcast or not, if yes, executing the next step; S6, determining whether the distance between the remote controller and the mobile phone is the preset distance or not according to the broadcast signals, if yes, executing the next step; S7, sending, by the mobile phone, a screen projection instruction to the digital television. According to the mobile phone screen projection method, the mobile phone only needs to knock the designated position of the remote controller, the mobile phone judges that the distance between the remote controller and the mobile phone is within the preset distance according to the broadcast signal, then a screen projection instruction is sent to the digital television, screen projection is completed, scanning by aiming at NFC or a two-dimensional code of the remote controller is not needed, and the screen projection efficiency is greatly improved.

Problems solved by technology

The current mobile screen projection technology usually uses NFC or QR code technology. Turn on the NFC of the mobile phone, read the NFC on the remote control through the mobile phone or scan the QR code on the TV interface to complete the screen projection. However, the mobile phone scans the remote control When using the NFC or QR code on the device, it must be adjusted to a suitable position to complete the scan code, otherwise the connection will not be completed, the efficiency of screen projection is not high, and it is difficult for the elderly and children to operate
