Example Embodiment

[0034] Example 1

[0035] Such as figure 1 As shown, this embodiment provides a screen-off method for a smart phone, and the screen-off method includes the following steps:

[0036] Step 101: Judge whether the mobile phone is in a call state, if yes, then go to step 102, if not, then the process is terminated;

[0037] Step 102: Determine whether the gravity sensor and the light sensor are both turned on, if yes, go to step 104, if not, go to step 103;

[0038] Step 103: Turn on the gravity sensor and the light sensor;

[0039] Step 104: The gravity sensor detects the three-axis acceleration value of the mobile phone in real time, and the light sensor detects the light intensity in real time;

[0040] Step 105: Calculate the angle between the mobile phone and the horizontal plane according to the three-axis acceleration value of the mobile phone;

[0041] Step 106: Determine whether the included angle is between 75° and 90°, and the light intensity is reduced to 0.5 lux within 1 second, i...

Example Embodiment

[0054] Example 2

[0055] Such as image 3 As shown, this embodiment provides a mobile terminal, which includes a gravity sensor 1, a light sensor 2, a screen 3, an earpiece 4, a first judgment module 5, a second judgment module 6, an opening module 7, a computing module 8, and a processing module 9.

[0056] The first judgment module 5 is used to judge whether the gravity sensor 1 and the light sensor 2 are both turned on, if so, the second judgment module 6 is activated, and if not, the activation module 7 is activated;

Abstract

The invention discloses a screen locking method for a mobile terminal and a mobile terminal. The mobile terminal comprises a gravity sensor, a light sensor, a screen and a receiver, and the photo is arranged on the surface of the receiver. The screen locking method for the mobile terminal comprises the steps of judging if the mobile terminal is in a phone state, if so , judging whether the gravity sensor and the photo sensor are both open; testing the triaxial acceleration of the mobile terminal through the gravity sensor and testing the light intensity through the light sensor; figuring out the included angle between the mobile terminal and the horizontal plane according to the triaxial acceleration; judging whether the included angle is in the range of a preset angle and whether the light intensity diminishes to be lower than a preset light intensity threshold value within a preset time period, if so, locking screen. According to the screen locking method for the mobile terminal and the mobile terminal, the gravity sensor and the light sensor arranged on the mobile terminal are used for achieving automatic screen locking during a call, and therefore cost is saved and accuracy is improved.

Description

Technical field [0001] The invention relates to a screen-off method of a mobile terminal and a mobile terminal. Background technique [0002] At present, the function of automatically turning off the screen of a mobile terminal during a call is realized by adding an infrared light emitting diode and an infrared light receiver in the mobile terminal. The infrared light-emitting diode continuously emits infrared light outwards. When the human ear approaches the mobile terminal to answer the call, the infrared light is reflected by the human ear back to the infrared light receiver, and the mobile terminal determines whether the mobile terminal is close to the human ear by detecting the intensity of the infrared light , So as to control whether the mobile terminal is off screen. This solution requires the addition of infrared light-emitting diodes and infrared light receivers on the basis of the original mobile terminal. The addition of additional hardware increases the cost and als...
