Determination of screen mode and screen gap for foldable IHS
An Information Handling System (IHS) includes a foldable display and is configured to determine a posture of the IHS based on the angle that the display is folded. The folded display is divided into first and second screen portions. Changes in the posture of the IHS are detected and the content and orientation of the content to display in the respective screen portions is determined. A gap is displayed along the fold of the foldable display, where the gap separates the screen portions along the fold. The width of the gap separating the screen portions may be determined based on the angle that the foldable display is folded and/or based on various additional aspects of the current posture of the IHS.
1. An Information Handling System (IHS) comprising:
a foldable display comprising a single display screen that is foldable along a folding portion of the screen;
a logic unit configured via firmware instructions to determine a posture of the IHS based in part on an angle at which the display is folded, wherein the folded display is divided by a fold into a first screen portion and a second screen portion; and
a processor configured via software instructions to:
detect a change in the posture of the IHS reported by the logic unit, wherein the display is folded at a first angle in the changed posture;
based on the first angle of the changed posture, determine a first width of a folded portion of the display screen that extends along the fold, wherein content displayed in the folded portion of the first width is distorted due to the fold;
determine content to display in the first screen portion and in the second screen portion;
in response to the detected change in posture of the IHS, display a gap of the first width along the folded portion of the display screen, wherein the first screen portion and the second screen portion are separated by the gap of the first width that displays distorted content that is not usable; and
determine an orientation of the content to display in the first screen portion and the second screen portion.
2. The IHS of claim 1 , wherein the foldable portion of the single display screen is along a hinge of the IHS.
3. The IHS of claim 1 , wherein the gap that is displayed by the single display screen comprises a black rectangle of the first width that is displayed along the foldable portion of the single display screen.
4. The IHS of claim 1 , wherein the first width of the gap that is displayed along the fold of the display screen is determined according to a quadratic equation that comprises an angle of the hinge as a variable.
5. The IHS of claim 4 , wherein the quadratic equation further comprises coefficients that are selected based on an application that is to displayed spanning the first screen portion and the second screen portion.
6. The IHS of claim 1 , wherein the first width of the gap that is displayed by the single display screen is determined based at least in part on an application that is to be displayed spanning the first screen portion and the second screen portion.
7. The IHS of claim 1 , wherein the first width of the gap that is displayed by the single display screen is determined based at least part on a brightness of the single display screen.
8. The IHS of claim 1 , wherein the width of the gap that is displayed by the single display screen is determined to be zero based on the posture of the IHS indicating that no separation is required between the first screen portion and the second screen portion since there is no distortion of content displayed along the fold.
9. A method for determining a screen mode for a foldable display of an IHS (Information Handling System), the method comprising:
determining a posture of the IHS based in part on an angle at which the display is folded, wherein the folded display comprising a single display screen that is foldable along a folding portion of the screen into a first screen portion and a second screen portion;
detecting a change in the posture of the IHS, wherein the display is folded at a first angle in the changed posture;
based on the first angle of the changed posture, determine a first width of a folded portion of the display screen that extends along the fold, wherein content displayed in the folded portion of the first width is distorted due to the fold;
determining content to display in the first screen portion and in the second screen portion;
in response to the detected change in posture of the IHS, displaying a gap of the first width along the folded portion of the display screen, wherein the first screen portion and the second screen portion are separated by the gap of the first width that displays distorted content that is not usable; and
determining an orientation of the content to display in the first screen portion and the second screen portion.
10. The method of claim 9 , wherein the foldable portion of the single display screen is along a hinge of the IHS.
11. The method of claim 9 , wherein the gap that is displayed by the single display screen comprises a black rectangle of the first width that is displayed along the foldable portion of the single display screen.
12. The method of claim 9 , wherein the first width of the gap that is displayed along the fold of the display screen is determined according to a quadratic equation that comprises an angle of the hinge as a variable.
13. The method of claim 12 , wherein the quadratic equation further comprises coefficients that are selected based on an application that is to displayed spanning the first screen portion and the second screen portion.
14. The method of claim 9 ,
wherein the first width of the gap that is displayed by the single display screen based at least in part on an application that is to be displayed spanning the first screen portion and the second screen portion.
15. The method of claim 9 , wherein the first width of the gap that is displayed by the single display screen is determined based at least part on a brightness of the single display screen.
16. The method of claim 9 , wherein the width of the gap that is displayed by the single display screen is determined to be zero based on the posture of the IHS indicating that no separation is required between the first screen portion and the second screen portion since there is no distortion of content displayed along the fold.
17. A computer-readable storage device of an IHS (Information Handling System) comprising a foldable display, wherein the storage device includes program instructions stored thereon that, upon execution by one or more processors, cause the one or more processors to:
determine a physical posture of the IHS based in part on an angle at which the display is folded, wherein the folded display comprises a single display screen that is foldable along a folding portion of the screen into a first screen portion and a second screen portion;
detect a change in the physical posture of the IHS, wherein the display is folded at a first angle in the changed posture;
based on the first angle of the changed posture, determine a first width of a folded portion of the display screen that extends along the fold, wherein content displayed in the folded portion of the first width is distorted due to the fold;
determine content to display in the first screen portion and in the second screen portion;
in response to the detected change in posture of the IHS, display a gap of the first width along the folded portion of the single display screen, wherein the first screen portion and the second screen portion are separated by the gap of the first width that displays distorted content that is not usable; and
determine an orientation of the content to display in the first screen portion and the second screen portion.
18. The computer-readable storage device of claim 17 , wherein the foldable portion of the single display screen is along a hinge of the IHS.
19. The computer-readable storage device of claim 17 , wherein the gap that is displayed by the single display screen comprises a black rectangle of the first width that is displayed along the foldable portion of the single display screen.
20. The computer-readable storage device of claim 19 , wherein the first width of the gap that is displayed along the fold of the display screen is determined according to a quadratic equation that comprises an angle of the hinge as a variable.
