mapping the first control to the third display region;

in response to mapping the first control to the third display region:

displaying the first control in a first area of the third display region; and

skipping lighting up areas of the third display region other than the first area;

detecting a first operation on the first control in the third display region; and

controlling, in response to detecting the first operation, the first display region or the second display region by executing a function corresponding to the first control in the first display region or the second display region.

2. The method of claim 1 , further comprising:

updating the first interface in the first display region or a second interface in the second display region; or

adjusting functions in the first display region and the second display region.

3. The method of claim 1 , further comprising retaining or deleting the first control from the first interface.

4. The method of claim 1 , wherein the first control is a preset control in the first interface, wherein the first control is specified by a user in the first interface, or wherein the first control is a most-frequently or a least-frequently used control in the first interface.

5. The method of claim 1 , wherein when a movie playing interface is displayed in the first display region or the second display region, the method further comprises:

detecting the first operation in the third display region; and

performing fast-forwarding or rewinding in the movie playing interface.

6. The method of claim 1 , wherein when an image preview interface is displayed in the first display region or the second display region, and the image preview interface comprises a first image, the method further comprises:

detecting the first operation in the third display region; and

zooming in or zooming out the first image.

7. The method of claim 1 , further comprising:

controlling the first display region when a first touch area in the first display region is smaller than or equal to a second touch area in the second display region; or

controlling the second display region when the first touch area is larger than the second touch area.

8. The method of claim 1 , further comprising:

controlling the first display region when a first distance between the second display region and a user is longer than a second distance between the first display region and the user; or

controlling the second display region when the first distance is shorter than the second distance.

9. The method of claim 1 , further comprising:

controlling the first display region when a first image from a first camera in the first display region comprises a user-specific feature; or

controlling the second display region when a second image from a second camera in the second display region comprises the user-specific feature.

10. The method of claim 1 , further comprising:

controlling the first display region when the first display region is in a screen-on state and the second display region is a screen-off state; or

controlling the second display region when the first display region is screen-off and the second display region is screen-on.

11. The method of claim 1 , further comprising:

adjusting a display brightness in the first display region or the second display region; or

adjusting a volume of the device.

12. An apparatus, comprising:

one or more processors;

a foldable screen coupled to the one or more processors and comprising a first display region, a second display region, and a third display region, wherein the third display region is disposed between the first display region and the second display region, and wherein when the apparatus is in a folded form, an included angle between the first display region and the second display region is less than or equal to a first preset angle; and

one or more memories coupled to the one or more processors and configured to store instructions that, when executed by the one or more processors, cause the apparatus to:

display a first interface in the first display region, wherein the first interface comprises a first control;

skip lighting up the third display region when displaying the first interface in the first display region;

map the first control to the third display region;

in response to mapping the first control to the third display region:

display the first control in the third display region; and

skip lighting up areas of the third display region other than the first area;

detect a first operation on the first control in the third display region; and

control, in response to detecting the first operation, the first display region or the second display region by executing a function corresponding to the first control in the first display region or the second display region.

13. The apparatus of claim 12 , wherein the instructions further cause the apparatus:

update the first interface in the first display region or a second interface in the second display region; or

adjust functions in the first display region and the second display region.

14. The apparatus of claim 12 , wherein the instructions further cause the apparatus to retain or delete the first control from the first interface.

15. The apparatus of claim 12 , wherein the instructions further cause the apparatus to:

use a preset control in the first interface as the first control;

use a control specified by a user in the first interface as the first control; or

use a most-frequently or a least-frequently used control in the first interface as the first control.

16. The apparatus of claim 12 , wherein when a movie playing interface is displayed in the first display region or the second display region, the instructions further cause the apparatus to:

detect the first operation in the third display region; and

perform fast-forwarding or rewinding in the movie playing interface.

17. The apparatus of claim 12 , wherein when an image preview interface is displayed in the first display region or the second display region, and the image preview interface comprises a first image, the instructions further cause the apparatus to:

detect the first operation in the third display region; and

zoom in or zoom out the first image.

18. The apparatus of claim 12 , wherein the instructions further cause the apparatus to:

control the first display region when a first touch area in the first display region is smaller than or equal to a second touch area in the second display region; or

control the second display region when the first touch area is larger than the second touch area.

19. The apparatus of claim 12 , wherein the instructions further cause the apparatus to:

control the first display region when a first distance between the second display region and a user is longer than a second distance between the first display region and the user; or

control the second display region when the first distance is shorter than the second distance.

20. The apparatus of claim 12 , wherein the instructions further cause the apparatus to:

control the first display region when a first image captured from a first camera in the first display region comprises a user-specific feature; or

control the second display region when a second image from a second camera in the second display region comprises the user-specific feature.
