Abstract

The present disclosure discloses a control method and an electronic device. The method is applied in an electronic device including a display screen. The display screen has a first display effect and a second display effect different from the first display effect. The method includes: detecting whether there is a first trigger signal when the display screen is providing the first display effect; and controlling the display screen to provide the second display effect upon detecting the first trigger signal. The second display effect includes at least a first display sub-effect that presents on the display screen a virtual image symmetrical to an object in front of the display screen. According to the embodiments of the present disclosure, a display screen of an electronic device has a first display effect and a second display effect and can be switched from the first display effect to the second display effect in response to a trigger signal. When the display screen is providing the second display effect, it can be used as a mirror.

Claims

1. A control method applied in an electronic device comprising a display screen, the display screen having a first display effect and a second display effect different from the first display effect, the method comprising:

detecting whether there is a first trigger signal when the display screen is providing the first display effect; and

controlling the display screen to provide the second display effect upon detecting the first trigger signal,

wherein the second display effect comprises at least a first display sub-effect that presents on the display screen a virtual image symmetrical to an object in front of the display screen.

2. The method of claim 1, wherein the second display effect further comprises a second display sub-effect that is identical to the first display effect, and

the first display sub-effect corresponds to a first display area on the display screen and the second display sub-effect corresponds to a second display area on the display screen.

3. The method of claim 2, wherein the display screen comprises an array of light emitting elements, and said controlling the display screen to provide the second display effect comprises:

controlling a first set of light emitting elements in the array of light emitting elements to have a luminance value lower than a luminance threshold, such that the first display sub-effect is provided in the first display area on the display screen that corresponds to the first set of light emitting elements, and

controlling a second set of light emitting elements in the array of light emitting elements to have a luminance value higher than the luminance threshold, such that the second display sub-effect is provided in the second display area on the display screen that corresponds to the second set of light emitting elements.

4. The method of claim 2, further comprising, after said controlling the display screen to provide the second display effect:

displaying a first application identifier in the second display area on the display screen in which the second display sub-effect is provided.

5. The method of claim 4, wherein the electronic device further comprises an array of capturing elements, and the method further comprises:

obtaining parameter information of a target object using the array of capturing elements; and

invoking a first application corresponding to the first application identifier based on the parameter information, such that a virtual image corresponding to the target object overlaps the identifier.

6. An electronic device, comprising:

a display screen having a first display effect and a second display effect different from the first display effect, the second display effect comprising at least a first display sub-effect that presents on the display screen a virtual image symmetrical to an object in front of the display screen;

a trigger signal detection unit configured to detect whether there is a first trigger signal when the display screen is providing the first display effect; and

a control unit configured to control the display screen to provide the second display effect upon detecting the first trigger signal.

7. The electronic device of claim 6, wherein the second display effect further comprises a second display sub-effect that is identical to the first display effect, and

the first display sub-effect corresponds to a first display area on the display screen and the second display sub-effect corresponds to a second display area on the display screen.

8. The electronic device of claim 7, wherein the display screen comprises an array of light emitting elements and the control unit is configured to:

control a first set of light emitting elements in the array of light emitting elements to have a luminance value lower than a luminance threshold, such that the first display sub-effect is provided in the first display area on the display screen that corresponds to the first set of light emitting elements, and

control a second set of light emitting elements in the array of light emitting elements to have a luminance value higher than the luminance threshold, such that the second display sub-effect is provided in the second display area on the display screen that corresponds to the second set of light emitting elements.

9. The electronic device of claim 7, wherein the control unit is further configured to:

display a first application identifier in the second display area on the display screen in which the second display sub-effect is provided.

10. The electronic device of claim 9, wherein the electronic device further comprises:

an array of capturing elements configured to capture parameter information of a target object, and

the control unit is further configured to obtain parameter information of a target object using the array of capturing elements and invoke a first application corresponding to the first application identifier based on the parameter information, such that a virtual image corresponding to the target object overlaps the identifier.
