Abstract

A display method for a foldable screen is provided, and is applied to an electronic device including a foldable screen. The foldable screen can be folded to form a first screen and a second screen. The method includes: in response to detecting that the foldable screen is in an unfolded form, the electronic device displays a first interface on the foldable screen in full screen mode, where the first interface runs on a first operating system. In response to detecting that the foldable screen is switched from the unfolded form to a half-folded form, the electronic device controls the first screen to display a second interface, and controls the second screen to display a third interface or to be turned off based on a location relationship between a horizontal plane and each of the first screen and the second screen.

First claim

1 . A display method applied to an electronic device comprising a foldable screen, wherein the foldable screen can be folded to form a first screen and a second screen, the method further comprising:
in response to detecting that the foldable screen is in an unfolded form, displaying, by the electronic device, a first interface on the foldable screen in full screen mode, wherein the first interface runs on a first operating system; and in response to detecting that the foldable screen is switched from the unfolded form to a half-folded form, controlling, by the electronic device, the first screen to display a second interface, and controlling the second screen to display a third interface or to be turned off based on a location relationship between a horizontal plane and each of the first screen and the second screen, and wherein in response to the foldable screen being in the unfolded form, an included angle between the first screen and the second screen is greater than a first angle threshold; and in response to the foldable screen is in the half-folded form, the included angle between the first screen and the second screen is between the first angle threshold and a second angle threshold, wherein the first angle threshold is greater than the second angle threshold.

2 . The method according to claim 1 , wherein the controlling,
by the electronic device, the first screen to display a second interface, and controlling the second screen to display a third interface or to be turned off, based on a location relationship between a horizontal plane and each of the first screen and the second screen comprises: determining, by the electronic device based on the location relationship between the horizontal plane and each of the first screen and the second screen, that a placement posture of the foldable screen is a first placement posture; and controlling, by the electronic device, to display the second interface on the first screen by running the first operating system, and to display the third interface on the second screen by running a second operating system, wherein in response to the foldable screen being in the first placement posture, the foldable screen is folded outward, an included angle between the first screen and the horizontal plane is between a third angle threshold and a fourth angle threshold, and an included angle between the second screen and the horizontal plane is between the third angle threshold and the fourth angle threshold, wherein the third angle threshold is greater than the fourth angle threshold.

3 . The method according to claim 1 , wherein the method further comprises:
in response to detecting that the foldable screen is switched from the half-folded form to a fully folded form, displaying, by the electronic device, a fourth interface on the first screen, and turning off the second screen, wherein the fourth interface runs on the first operating system; and when the foldable screen is in the fully folded form, the included angle between the first screen and the second screen is less than the second angle threshold.

4 . The method according to claim 1 , wherein the controlling, by the electronic device, to display a second interface on the first screen, and to display a third interface on the second screen, based on a location relationship between a horizontal plane and each of the first screen and the second screen specifically further comprises:
determining, by the electronic device based on the location relationship between the horizontal plane and each of the first screen and the second screen, that a placement posture of the foldable screen is a second placement posture; and controlling, by the electronic device, the first screen to display the second interface, and turning off the second screen, wherein the second interface runs on the first operating system; and in response to the foldable screen being in the second placement posture, the foldable screen is folded outward, and an included angle between the second screen and the horizontal plane is less than a fifth angle threshold.

5 . The method according to claim 4 , wherein the second interface comprises a function control and the method further comprises:
receiving, by the electronic device, a first operation performed by a user on the function control; and in response to the first operation, enabling, by the electronic device, a function corresponding to the function control.

6 . The method according to claim 5 , wherein the enabling, by the electronic device, a function corresponding to the function control comprises:
opening, by the electronic device, a flash; or opening, by the electronic device, a camera on the first screen, and displaying, on the first screen, an image captured by the camera on the first screen.

7 . The method according to claim 1 , wherein the controlling, by the electronic device, the first screen to display a second interface, and controlling the second screen to display a third interface or to be turned off based on a location relationship between a horizontal plane and each of the first screen and the second screen specifically comprises:
determining, by the electronic device based on the location relationship between the horizontal plane and each of the first screen and the second screen, that a placement posture of the foldable screen is a third placement posture; and controlling, by the electronic device, the first screen to display the second interface, and controlling running of the second screen to display the third interface, wherein the second interface comprises a first part of displayed content in the first interface, and the third interface comprises a second part of the displayed content in the first interface; and in response to the foldable screen being in the third placement posture, the foldable screen is folded inward, an included angle between the first screen and the horizontal plane is between a sixth angle threshold and a seventh angle threshold, and an included angle between the second screen and the horizontal plane is between the sixth angle threshold and the seventh angle threshold, wherein the sixth angle threshold is less than 90 degrees, and wherein the seventh angle threshold is greater than 90 degrees.

8 . The method according to claim 1 , wherein the controlling,
by the electronic device, the first screen to display a second interface- and controlling the second screen to display a third interface or to be turned off based on a location relationship between a horizontal plane and each of the first screen and the second screen comprises: determining, by the electronic device based on the location relationship between the horizontal plane and each of the first screen and the second screen, that a placement posture of the foldable screen is a fourth placement posture; and controlling, by the electronic device, the first screen to display the second interface, determining an operation control corresponding to the second interface, and controlling running of the second screen to display the third interface, wherein the third interface comprises the operation control corresponding to the second interface; and in response to the foldable screen being in the fourth placement posture, the foldable screen is folded inward, and an included angle between the second screen and the horizontal plane is less than an eighth angle threshold.

9 . An electronic device, comprising:
a foldable screen, wherein the foldable screen is divided into a first screen and a second screen by a folding line when being folded; one or more processors; and one or more memories, wherein the foldable screen can be folded to form at least two screens, the at least two screens comprise the first screen and the
