Method and device for controlling screen state of electronic equipment through protective case

Abstract

The invention relates to a method and device for controlling the screen state of electronic equipment through a protection cover. According to the method, a function module structure is established, computer program instructions are used for controlling a computer system for completing the method, and the computer program instructions are stored in a computer readable storage medium. A screen of the electronic equipment is a touch screen, when the screen state is in a bright screen state, if a blocking object in a preset distance in front of the screen and touch action on the screen are sensed at the same time, the state of the screen is converted from the bright screen state to a dark screen state; when the screen state is converted to the dark screen state, if no blocking objects in the preset distance in front of the screen and no touch action on the screen are sensed at the same time, the state of the screen is converted from the dark screen state to the bright screen state. A metal sheet is arranged on a turning cover of the protection cover, then control over the screen state can be achieved, a Hall device and a magnet are removed, and cost is saved.

Description

technical field [0001] The invention relates to a method for controlling the screen state of an electronic device through a protective cover. The method is completed by establishing a functional module framework and controlling a computer system by computer program instructions, and the computer program instructions are stored in a computer-readable storage medium. Background technique [0002] At present, the protective covers of some mobile devices such as mobile phones or tablet computers are provided with a flip cover for protecting the screen. After the screen is turned off for standby, the flip cover of the protective cover is closed, and then opened when it is to be used, to prevent the screen from being scratched. Therefore, some mobile phones or tablet computers use the cover of the protective case to control the state of the screen. When the cover of the protective cover is closed, the state of the screen is automatically switched to off screen. When the cover of t...

However, in the existing method of using Hall devices to control the state of the screen, it is necessary to install Hall devices inside mobile devices such as mobile phones or tablet computers, and to set magnets on the cover of the protective cover. Hall devices are not mobile phones. Or the sensor devices commonly used in mobile devices such as tablet computers. In order to realize this function, adding this sensor will increase the cost. At the same time, setting the magnet in the flip of the protective case will also increase the cost.
