Problems solved by technology

[0002] Users use mobile phones, computers and other electronic devices more and more frequently. Because different electronic devices have their own characteristics, users often need to coordinate the use of different electronic devices, especially for projection operations. However, there is currently no flexible and convenient projection method, the data to be projected can only be transmitted from the first device to the projector when both electronic devices are turned on, and then the projector can project the data. This projection method is complicated and requires relatively large system resources. Consumption, but also has high hardware requirements, such as must have a projector, thus raising the threshold of projection

Abstract

The present application discloses a screen projection control method and a first electronic device. The method includes: obtaining a first control instruction in a power-off state, and generating connection information according to the first control instruction, so that the second electronic device can The above connection information establishes a data connection with the first electronic device; receives the projection data transmitted by the second electronic device, and processes the projection data to generate a corresponding projection file; wakes up the projection component of the first electronic device to Projecting the projection file on the first screen of the first electronic device. The method enables the first electronic device to receive projection data in a power-off state and perform projection operations based on the projection data, which simplifies the complicated steps of screen projection operations while occupying very few system resources, and greatly facilitates users screen mirroring operation.

Description

technical field [0001] The present application relates to the field of information processing of electronic devices such as mobile phones and computers, and in particular to a screen projection control method and a first electronic device. Background technique [0002] Users use mobile phones, computers and other electronic devices more and more frequently. Because different electronic devices have their own characteristics, users often need to coordinate the use of different electronic devices, especially for projection operations. However, there is currently no flexible and convenient projection method, the data to be projected can only be transmitted from the first device to the projector when the two electronic devices are turned on, and then the data is projected by the projector. This projection method is complicated and requires relatively large system resources. It also has high hardware requirements, such as a projector, which raises the threshold for projection. ...
