controlling the retractable display screen to stretch, to add the display region of the region size.

7. The device control method according to claim 5 , wherein said displaying the second display content in the added display region comprises:

displaying the second display content in accordance with the display policy.

8. The device control method according to claim 1 , wherein said determining the second display content to be displayed in addition to the first display content that is currently displayed comprises:

monitoring a notification event in the electronic device; and

determining, based on the notification event, the second display content to be displayed.

9. A non-transitory computer-readable storage medium, having a computer program stored thereon, wherein the computer program, when executed on a computer, causes the computer to perform a device control method applied in an electronic device comprising a retractable display screen, the device control method comprising:

determining a second display content to be displayed in addition to a first display content that is currently displayed;

controlling, based on the second display content, the retractable display screen to stretch, for adding a display region beyond a current display region in which the first display content is displayed; and

displaying the second display content in the added display region, and continuing displaying the first display content in the current display region,

wherein the device control method further comprises:

providing a Software Development Kit (SDK) functional interface used for controlling stretching or retraction of the retractable display screen,

wherein said determining the second display content to be displayed in addition to the first display content that is currently displayed comprises:

in response to receiving from a third-party application an invoking instruction for the SDK functional interface, determining, based on the invoking instruction, the second display content to be displayed by the third-party application.

10. The non-transitory computer-readable storage medium according to claim 9 , wherein the method further comprises:

displaying, in the added display region, an interaction entry corresponding to the second display content; and

receiving, via the interaction entry, an input operation for the second display content, and responding to the input operation.

11. An electronic device, comprising a processor and a memory, wherein the memory has a computer program stored thereon; and the processor is configured to invoke the computer program to:

determine a second display content to be displayed in addition to a first display content that is currently displayed;

control, based on the second display content, the retractable display screen to stretch, for adding a display region beyond a current display region used for displaying the first display content; and

display the second display content in the added display region, and continuing displaying the first display content in the current display region,

wherein the processor is further configured to:

provide an SDK functional interface used for controlling stretching or retraction of the retractable display screen; and

wherein said determining the second display content to be displayed in addition to the first display content currently displayed comprises:

in response to receiving from a third-party application an invoking instruction for the SDK functional interface, determine, based on the invoking instruction, the second display content to be displayed by the third-party application.

12. The electronic device according to claim 11 , wherein the processor is further configured to:

display, in the added display region, an interaction entry corresponding to the second display content; and

receive, via the interaction entry, an input operation for the second display content, and responding to the input operation.

13. The electronic device according to claim 12 , wherein the processor is further configured to:

in response to detecting no input operation for the interaction entry within a predetermined time length, end display of the second display content, and restore the retractable display screen to a state prior to the stretching.

14. The electronic device according to claim 12 , wherein the processor is further configured to:

restore the retractable display screen to a state prior to the stretching.

15. The electronic device according to claim 11 , wherein the processor is further configured to:

obtain feature information of the second display content; and

obtain a display policy matching the feature information.

16. The electronic device according to claim 15 , wherein the processor is further configured to:

determine, based on the display policy, a region size required to display the second display content; and

control the retractable display screen to stretch, to add the display region of the region size.
