Abstract
A display control method applied to a mobile terminal, which includes a display and is coupled to an external device, includes when the mobile terminal is on a voice call, using the external device; determining that the mobile terminal is in a handheld state or a non-handheld state; when the mobile terminal is in the handheld state, controlling the display to be in a screen-on state; and when the mobile terminal is in the non-handheld state, controlling the display to be in a screen-off state.
Claims20
A display control method implemented by a mobile terminal, wherein the display control method comprises:
- detecting, when the mobile terminal is on a voice call using a connection to an external device, that the mobile terminal is in a handheld state or a non-handheld state;
- detecting, by an ambient light sensor of the mobile terminal, that a light luminance of an ambient environment of the mobile terminal is less than or equal to a luminance threshold;
- controlling a display of the mobile terminal to be in a screen-on state when the mobile terminal is in the handheld state and when the light luminance is less than or equal to the luminance threshold;
- and
- controlling the display to be in a screen-off state when the light luminance is greater than or equal to the luminance threshold.
A display control method implemented by a mobile terminal, wherein the display control method comprises:
- detecting, when the mobile terminal is on a voice call using a connection to an external device, that a camera of the mobile terminal captures a face image;
- detecting, by an ambient light sensor of the mobile terminal, that a light luminance of an ambient environment of the mobile terminal is less than or equal to a luminance threshold;
- controlling a display of the mobile terminal to be in a screen-on state when the camera captures the face image and when the light luminance is less than or equal to the luminance threshold;
- and
- controlling the display to be in a screen-off state when the light luminance is greater than or equal to the luminance threshold.
A mobile terminal comprising:
- a display;
- and
- a processor coupled to the display and configured to:
- detect, when the mobile terminal is on a voice call using a connection to an external device, that the mobile terminal is in a handheld state or a non-handheld state;
- detect, by an ambient light sensor of the mobile terminal, that a light luminance of an ambient environment of the mobile terminal is less than or equal to a luminance threshold;
- control the display to be in a screen-on state when the mobile terminal is in the handheld state and when the light luminance is less than or equal to the luminance threshold;
- and
- control the display to be in a screen-off state when the light luminance is greater than or equal to the luminance threshold.
