Embodiment Construction

[0036] An embodiment of the present invention provides a control method and device. The method includes: obtaining the duration of the user's eyeball gaze on the display screen through a sensor, and determining whether the duration is greater than or equal to a first preset threshold; if the duration is greater than or equal to the first threshold When a preset threshold is reached, the backlight of the display screen is turned off. That is to say, the electronic device can detect the duration of the user's gaze at the display screen. If the user's gaze at the display screen is too long, the electronic device will turn off the backlight of its own display screen, thereby prompting the user to take a short rest, thereby protecting the user's eyesight. healthy.

[0037] The technical solutions of the present invention will be described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention...

Abstract

The invention discloses a control method and a control device. The control method comprises the steps of acquiring duration time of eyeballs of a user staring on a display screen by virtue of a sensor, judging whether the duration time is larger than or equal to a first preset threshold, and turning off background light of the display screen when the duration time is larger than or equal to the first preset threshold. In other words, electronic equipment can detect the duration time of the user staring on the display screen, and if the time of the user staring on the display screen is too long, the electronic equipment will turn off the background light of the display screen so as to prompt the user to temporarily take a rest, so that the vision health of the user is protected.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a control method and device. Background technique [0002] With the development and progress of electronic technology, various portable electronic devices have been applied to every user's life, such as portable electronic devices such as notebook computers, tablet computers, and mobile phones. [0003] Since functions of portable electronic devices such as mobile phones are becoming more and more powerful, users can use portable electronic devices in various scenarios, which brings great convenience to users. [0004] At present, if the user stares at the display screen of the electronic device for a long time, the visual health of the user will be affected, and the current electronic device cannot effectively remind this situation. Contents of the invention [0005] The present invention provides a control method and device, which are used to solve the problem ...
