Abstract

The embodiments of the present invention disclose a method for controlling a screen state of a mobile device and a related mobile device. The method according to the embodiments of the present invention includes: judging, when a mobile device is in a standby screen-off state and a screen turn-on instruction is received, whether a cover exists within a preset distance in front of a proximity sensor of the mobile device. If a cover exists within the preset distance in front of the proximity sensor, the mobile device stays in the standby screen-off state, and if no cover exists within the preset distance in front of the proximity sensor, the mobile device switches from the standby screen-off state to a screen-on state. By implementing the solutions in the present invention, battery power of the mobile device can be saved, and time for using the mobile device can be prolonged.

Claims

1. A method for controlling a screen state of a mobile device, comprising:

judging, when a mobile device is in a standby screen-off state and a screen turn-on instruction is received, whether a cover exists within a preset distance in front of a proximity sensor of the mobile device, wherein

if a cover exists within the preset distance in front of the proximity sensor, the mobile device stays in the standby screen-off state; and

if no cover exists within the preset distance in front of the proximity sensor, the mobile device switches from the standby screen-off state to a screen-on state.

2. The method according to claim 1, wherein the judging whether a cover exists within a preset distance in front of a proximity sensor of the mobile device comprises:

triggering the proximity sensor, so as to obtain a distance between the proximity sensor and a cover; and

judging whether the distance is greater than the preset distance, if the distance is not greater than the preset distance, it is determined that a cover exists within the preset distance in front of the proximity sensor, and if the distance is greater than the preset distance, it is determined that no cover exists within the preset distance in front of the proximity sensor.

3. The method according to claim 1, wherein,

the proximity sensor is an infrared proximity sensor, or a linear proximity sensor, or an ultrasonic proximity sensor.

4. The method according to claim 1, wherein,

the standby screen-off state is a state in which the mobile device does not display operation content and a backlight is turned off.

5. The method according to claim 1, wherein,

the screen-on state is a state in which the mobile device displays operation content and a backlight is turned on.

6. The method according to claim 1, wherein,

the standby screen-off state comprises a music playing screen-off state and a radio listening screen-off state.

7. The method according to claim 1, wherein,

the screen turn-on instruction is an operation instruction that is sent when a screen turn-on button is pressed.

8. A mobile device, comprising:

a judging module, configured to judge, when the mobile device is in a standby screen-off state and a screen turn-on instruction is received, whether a cover exists within a preset distance in front of a proximity sensor of the mobile device; and

a controlling module, configured to;

if a cover exists within the preset distance in front of the proximity sensor, control the mobile device to stay in the standby screen-off state; and

if no cover exists within the preset distance in front of the proximity sensor, control the mobile device to switch from the standby screen-off state to a screen-on state.

9. The mobile device according to claim 8, wherein,

the proximity sensor is configured to obtain a distance between the proximity sensor and the cover.

10. The mobile device according to claim 8, wherein,

the proximity sensor is an infrared proximity sensor, or a linear proximity sensor, or an ultrasonic proximity sensor.
