Abstract

A device comprises a display arrangement which includes a plurality of displays that are movable relative to each other such that a plurality of display configurations can be achieved. Each of the display configurations provides a combined display area which is different for at least two of the display configurations. An application processor is operable to execute a plurality of user applications, each of which can provide a display output. A display driver is arranged to generate an arrangement of display output for the display arrangement from the display output of an application being executed. The display driver sets a display characteristic for the arrangement of display output in response to a characteristic of the executed application and the deployed display configuration. For example, depending on the application being executed and the current display configuration, a size of a display window used for the application can be selected.

Claims

1. A device comprising:

a display arrangement (201) comprising a plurality of displays movable relative to each other to provide a plurality of display configurations, each display configuration providing a combined display area, and the combined display area for at least some of the display configurations being different;

an application processor (203) operable to execute a plurality of user applications providing display outputs;

a display driver (205) arranged to generate an arrangement of display output for the display arrangement from a display output of a first application of the plurality of user applications being executed; and

a display manager (207) arranged to set a display characteristic for the arrangement of display output in response to a deployed display configuration and a characteristic of the first application.

2. The device of claim 1 wherein the characteristic of the first application comprises an identification of the first application.

3. The device of claim 1 wherein the display manager (207) is arranged to set the display characteristic in response to a maximum display size for the deployed display configuration.

4. The device of claim 1 wherein the display characteristic comprises a size characteristic of an image section of a display area of the deployed display configuration being used for displaying the display output of the first application.

5. The device of claim 1 wherein the display characteristic comprises an overlap characteristic of an image section of a display area of the deployed display configuration being used for displaying the display output of the first application, the overlap characteristic being indicative of an overlap of the image section among the plurality of displays.

6. The device of claim 1 wherein the display manager (207) is arranged to generate a rule relating a display characteristic setting and a characteristic of at least one of a property of the first application and a property of the deployed display configuration in response to a user input, and to determine the display characteristic in response to the rule.

7. The device of claim 1 further comprising a user preference processor arranged to determine a user display preference in response to a previous user operation of the device;

wherein the display manager (207) is arranged to generate a rule relating a display characteristic setting and a characteristic of at least one of a property of the first application and a property of the deployed display configuration in response to the user display preference, and to determine the display characteristic in response to the rule.

8. The device of claim 1 wherein at least a section of at least one display of the plurality of displays is a touch-sensitive display capable of receiving a user input;

and wherein the display characteristic comprises a size characteristic for an area of the section allocated to receive user inputs and a size characteristic for an area of the section allocated to display at least part of the display output of the first application.

9. The device of claim 8 further comprising a user-input processor (209) for generating a user input display image for the area of the section allocated to receive user inputs;

and means for generating a user input for the first application in response to a touch input detected in the area of the section allocated to receive user inputs.

10. The device of claim 1 wherein the first application is arranged to generate the display output in response to a received data stream;

and the display manager (207) is arranged to set the display characteristic in response to a characteristic of the received data stream.

11. The device of claim 10 wherein the received data stream is a video data stream, and wherein the characteristic of the received data stream comprises a video quality characteristic for the video data stream.

12. The device of claim 1 wherein the first application is arranged to generate the display output in response to a data stream received from a remote source;

and the device is further arranged to request the remote source to set a characteristic of the data stream in response to a characteristic of the deployed display configuration.

13. The device of claim 12 wherein the characteristic of the data stream comprises at least one characteristic selected from the group consisting of:

a data rate of the data stream,

a communication quality level of the data stream,

a content quality level of the data stream, and

a resolution of the data stream.

14. The device of claim 1 further comprising at least one actuator for moving at least one display of the plurality of displays relative to at least one other display of the plurality of displays to reach a display configuration in response to a characteristic of a received data stream processed by the first application.

15. The device of claim 1 further comprising:

a receiver (211) for receiving a display control signal from a remote source; and

at least one actuator for moving at least one display of the plurality of displays relative to at least one other display of the plurality of displays to reach a display configuration in response to the display control signal.

16. The device of claim 1 wherein a first display of the plurality of displays is rotatably attached to a second display of the plurality of displays along a first edge of the first display and a first edge of the second display;

wherein a third display of the plurality of displays is rotatably attached to the first display along a second edge of the first display and along a first edge of the third display; and

wherein a fourth display of the plurality of displays is rotatably attached to the second display along a second edge of the second display and along a first edge of the fourth display.

17. The device of claim 16 wherein the first edge of the first display is at an angle of substantially 90°

relative to the second edge of the first display; and

wherein the first edge of the second display is at an angle of substantially 90°

relative to the second edge of the second display.

18. The device of claim 16 wherein the first display, the second display, the third display, and the fourth display have substantially identical sizes.

19. The device of claim 1 wherein a combined display area for one of the display configurations corresponds to a display area of one display of the plurality of displays.

20. A method of operation for a device including a display arrangement (201) comprising a plurality of displays movable relative to each other to provide a plurality of display configurations, each display configuration providing a combined display area, and the combined display area for at least some of the display configurations being different, the method comprising:

an application processor (203) executing a first application of a plurality of user applications providing display outputs;

generating an arrangement of display output for the display arrangement from the display output of the first application; and

setting a display characteristic for the arrangement of display output in response to a deployed display configuration and a characteristic of the first application.
