Problems solved by technology
[0003] When the traditional mobile terminal is indoors and other scenes, when there is no object close to the mobile terminal, the detected infrared value is generally relatively stable, but in an environment with relatively strong light, it is easy to be interfered by strong light, which may easily cause the detected infrared value to jitter , suddenly big and small, jumping up and down between the threshold of the screen off and the screen on, causing the screen of the mobile terminal to appear a flickering phenomenon that changes from one on to one off, reducing the stability of the mobile terminal on the control of the screen on and off

Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0021] It can be understood that the terms "first", "second" and the like used in the present invention can be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first client could be termed a second client, and, similarly, a second client could be termed a first client, without departing from the scope of the present invention. Both the first client and the second client are clients, but they are not the same client.

The invention relates to a screen-off control method and device for a mobile terminal. The method comprises steps as follows: infrared energy values received designated times by a proximity sensor continuously are acquired; the largest infrared energy value and the smallest infrared energy value are acquired from the infrared energy values acquired designated times continuously, and the difference between the largest infrared energy value and the smallest infrared energy value is acquired; if the difference between the largest infrared energy value and the smallest infrared energy value is detected to be higher than a first energy threshold value, the screen-off control mode is switched to an anti-inference mode, and the anti-inference mode means that a screen-off threshold value is configured to be a preset infrared energy value for controlling screen-off operation. When data jitter occurs to the infrared energy value detected in the environment with superstrong light, the situation of constant switching between a screen-off state and a screen-on state cannot occur, and screen splashing is also avoided.
Description
technical field [0001] The present invention relates to a mobile terminal, in particular to a control method and device for turning off the screen of a mobile terminal. Background technique [0002] With the development of mobile communication technology, more and more users use mobile terminals to make calls or transmit information. When using a mobile terminal to make a call, it is sometimes necessary to bring the mobile terminal close to a person's face. In order to prevent misoperation or save power when approaching, the screen is usually turned off when the mobile terminal is close to the person's face. When the mobile terminal is far away from the face, the screen is on for the convenience of the user. [0003] When the traditional mobile terminal is indoors and other scenes, when there is no object close to the mobile terminal, the detected infrared value is generally relatively stable, but in an environment with relatively strong light, it is easy to be interfered b...
