Use a Hall effect sensor to prevent the protective case from accidentally turning off the screen on the device

摘要

The present invention provides a terminal control method, a protective case, and a terminal. In the method, the terminal is arranged with two Hall-effect sensors for detecting the change of magnetic field generated by the magnet in the protective case, and identifies the forward snap-fit operation, the opening operation, the rear snap-fit operation, etc. of the protective case. be able to. The terminal may perform a screen off operation upon detecting a forward snap fit operation of the protective case, or the terminal may skip performing a screen off operation upon detecting a rear snap fit operation of the protective case. In the embodiment of the present invention, in order to improve the accuracy of terminal control, it is possible to prevent the protective case from accidentally turning off the screen.
