Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a controller of a user device having a rollable display device may obtain fingerprint information associated with a user interaction with a contact area of the rollable display device. The controller may obtain touch information associated with the user interaction with the contact area of the rollable display device. The controller may output, based on the fingerprint information and the touch information, actuation information that causes actuation of a display extending component of the rollable display device to change an extension state of the rollable display device. Numerous other aspects are described.

First claim

What is claimed is:

1 . A controller of a user device for wireless communication, the user device comprising a rollable display device, comprising:
a memory; and one or more processors coupled to the memory and configured to cause the controller to:
obtain fingerprint information associated with a user interaction with a contact area of the rollable display device;
obtain touch information associated with the user interaction with the contact area of the rollable display device; and
output, based on the fingerprint information and the touch information, actuation information that causes actuation of a display extending component of the rollable display device to change an extension state of the rollable display device, wherein the display extending component comprises a mechanical device that is actuated to one or more of extend or retract a rollable display panel of the rollable display device, and wherein the mechanical device comprises a motor that is calibrated to enable the rollable display panel to be extended at a particular rate.

2 . The controller of claim 1 , wherein the one or more processors are further configured to cause the controller to output representation information that facilitates presentation of a virtual button on a user interface associated with the rollable display device, wherein the virtual button corresponds to the contact area.

3 . The controller of claim 1 , wherein the one or more processors, to cause the controller to output the actuation information, are configured to cause the controller to output the actuation information based on the touch information satisfying a touch condition.

4 . The controller of claim 3 , wherein the touch information comprises a force measurement associated with the user interaction with the contact area, and wherein the touch information satisfies the touch condition based on the force measurement satisfying a force threshold.

5 . The controller of claim 3 , wherein the touch information comprises a gesture measurement associated with the user interaction with the contact area, and wherein the touch information satisfies the touch condition based on the gesture measurement satisfying a gesture threshold.

6 . The controller of claim 1 , wherein the actuation information causes actuation of the display extending component to change the extension state from an unextended state to an extended state.

7 . The controller of claim 1 , wherein the actuation information causes actuation of the display extending component to change the extension state from an extended state to an unextended state.

8 . The controller of claim 1 , wherein the one or more processors are further configured to cause the controller to output mode information that causes the rollable display device to transition from a first lock mode to a second lock mode.

9 . The controller of claim 8 , wherein the one or more processors, to cause the controller to output the mode information, are configured to cause the controller to output the mode information based on the fingerprint information satisfying a fingerprint condition.

10 . The controller of claim 1 , wherein the rollable display device comprises the rollable display panel, and wherein the mechanical device is calibrated to enable a lower edge of the rollable display panel and an upper edge of the rollable display panel to extend at the particular rate.

11 . A method for controlling a rollable display device, comprising:
obtaining, by a fingerprint acquisition component of the rollable display device, fingerprint information associated with a user interaction with a contact area of the rollable display device; obtaining, by a touch sensing component of the rollable display device, touch information associated with the user interaction with the contact area of the rollable display device; and outputting, based on the fingerprint information and the touch information, actuation information that causes actuation of a display extending component of the rollable display device to change an extension state of the rollable display device, wherein the display extending component comprises a mechanical device that is actuated to one or more of extend or retract a rollable display panel of the rollable display device, and wherein the mechanical device comprises a motor that is calibrated to enable the rollable display panel to be extended at a particular rate.

12 . The method of claim 11 , further comprising outputting representation information that facilitates presentation of a virtual button on a user interface associated with the rollable display device, wherein the virtual button corresponds to the contact area.

13 . The method of claim 11 , wherein outputting the actuation information comprises outputting the actuation information based on the touch information satisfying a touch condition.

14 . The method of claim 13 , wherein the touch information comprises a force measurement associated with the user interaction with the contact area, and wherein the touch information satisfies the touch condition based on the force measurement satisfying a force threshold.

15 . The method of claim 11 , wherein the actuation information causes actuation of the display extending component to change the extension state from an unextended state to an extended state.

16 . The method of claim 11 , wherein the actuation information causes actuation of the display extending component to change the extension state from an extended state to an unextended state.

17 . The method of claim 11 , further comprising outputting mode information that causes the rollable display device to transition from a first lock mode to a second lock mode.

18 . The method of claim 17 , wherein outputting the mode information comprises outputting the mode information based on the fingerprint information satisfying a fingerprint condition.

19 . The method of claim 11 , wherein the rollable display device comprises the rollable display panel, and wherein the mechanical device is calibrated to enable a lower edge of the rollable display panel and an upper edge of the rollable display panel to extend at the particular rate.

20 . A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a controller of a user device having a rollable display device, cause the controller to:
obtain fingerprint information associated with a user interaction with a contact area of the rollable display device;
obtain touch information associated with the user interaction with the contact area of the rollable display device; and
output, based on the fingerprint information and the touch information, actuation information that causes actuation of a display extending component of the rollable display device to change an extension state of the rollable display device, wherein the display extending component comprises a mechanical device that is actuated to one or more of extend or retract a rollable display panel of the rollable display device, and wherein the mechanical device comprises a motor that is calibrated to enable the rollable display panel to be extended at a particular rate.

21 . The non-transitory computer-readable medium of claim 20 , wherein the one or more instructions further cause the controller to output representation information that facilitates presentation of a virtual button on a use
