Abstract

The invention discloses a screen control method and a screen control device. The screen control method comprises the following steps: when Hall potential change is detected on electronic equipment by using a Hall sensor, judging whether an environment of the electronic equipment is disturbed by a disturbing magnetic field or not; when confirming that the environment of the electronic equipment is disturbed by the disturbing magnetic field, detecting the distance between a protecting sleeve of the electronic equipment and the screen of the electronic equipment by using a distance sensor; judging whether a screen lightening event or screen off event is triggered or not according to the distance, wherein the screen lightening event is an event that the screen of the electronic equipment is lightened, and the screen off event is an event that the screen of the electronic equipment is powered off. With the combination of the Hall sensor and the distance sensor, mal-judgment caused by the situation that disturbance of the disturbing magnetic field is only judged according to the output result of the Hall sensor can be avoided, and thus poor use experience caused by the mal-judgment can be avoided for users.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a screen control method and device. Background technique [0002] With the development of science and technology, electronic devices such as mobile phones and tablet computers are becoming more and more popular among users, and there are more and more occasions for users to use electronic devices. In order to protect the electronic equipment from being damaged, the electronic equipment may be equipped with a protective case. By installing Hall sensors on the motherboard of the electronic device and installing magnets on the protective cover, the electronic device can be combined with the protective cover to control the screen of the electronic device to turn on or off. For example, when the protective cover is closed, the magnet on the protective cover causes a potential change inside the Hall sensor, which triggers a screen-off event, thereby turning off the scree...
