Abstract

A display system within a reduced resource information handling system is disclosed. In a particular form, a method of outputting video is disclosed. The method can include detecting an operating condition of an internal display and an external display of an information handling system. The information handling system can include a host processing system and a remote processing system. The method can further include detecting a video output signal configured to be displayed during a reduced operating state of the host processing system. The method can also include coupling the video output signal to either the internal display or the external display.

Claims

1. A display module comprising:

a display configured to be coupled along an external portion of a housing of an information handling system; and

a display module interface configured to be coupled to a video multiplexer of a host processing system of the information handling system, wherein the host processing system is configured to receive a video output signal from a remote processing system.

2. The display module of claim 1, further comprising:

an input interface configured to receive a user input to manipulate content displayed within the display; and

wherein the display module interface is further configured to couple an input signal to the remote processing system in response to the user input.

3. The display module of claim 2, further comprising a first access button operably coupled to the input interface, wherein the input interface is operable to initiate access to a first resource of the host processing system during a reduced operating state of the host processing system.

4. The display module of claim 2, wherein the display is configured to be enabled when a cover of the host processing system is in a closed position.

5. The display module of claim 4, wherein the display is configured to be disabled when the cover of the host processing system is in an open position.

6. The display module of claim 2, wherein the input interface further comprises:

an email access button configured to access an email application of the remote processing system during the reduced operating state;

a contacts access button configured to access a contacts application of the remote processing system during the reduced operating state;

a calendar access button configured to access a calendar application of the remote processing system during the reduced operating state; and

an Internet access button configured to access an Internet application of the remote processing system during the reduced operating state.

7. The display module of claim 1, wherein the display interface is further configured to receive a video input signal from the remote processing module during the reduced operating state.

8. The display module of claim 1, wherein the display interface is further configured to receive a video input signal from the host processing system during a run operating state of the host processing system.

9. The display module of claim 1, wherein:

the display is a security enabled display operable to output a video output upon validating a user of the information handling system; and

the display is integrated as a part of the housing of the host processing system.

10. A method of outputting video comprising:

detecting an operating condition of an internal display and an external display of an information handling system, wherein the information handling system includes a host processing system and a remote processing system;

detecting a video output signal configured to be displayed during a reduced operating state of the host processing system; and

coupling the video output signal to either the internal display or the external display.

11. The method of claim 10, further comprising:

detecting a closed lid of the information handling system;

enabling the remote processing system;

disabling the host processing system;

enabling the external display; and

outputting the video output signal to the external display.

12. The method of claim 11, further comprising:

enabling an input interface in response to detecting the closed lid;

detecting a user selected input at the input interface;

coupling a input signal to the remote processing system in response to the user elected input; and

enabling a function using the remote processing system.

13. The method of claim 10, further comprising:

detecting a video input signal at the remote processing system during a reduced operating state of the host processing system;

determining whether to output the video input signal to the internal display or the external display; and

outputting the video input signal in response to the determining.

14. The method of claim 12, further comprising:

detecting a reduced operating state of the host processing system; and

enabling the remote processing system to process the user selected input.

15. The method of claim 10, further comprising:

detecting a first video input signal of the host processing system;

detecting a second video input signal of the remote processing system;

multiplexing the first video input signal and the second video signal to generate a multiplex video signal; and

outputting the multiplexed video signal.

16. The method of claim 15, further comprising:

detecting a closed lid of the host processing system;

outputting the multiplexed video signal to the external display in response to detecting the closed lid;

detecting an opening of the closed lid;

enabling the internal display;

disabling the external display; and

outputting the multiplexed video signal to the internal display.

17. An information handling system comprising:

a housing configured to house electronics of a host processing system and a remote processing system; and

an external display integrated along an exterior portion of the housing, wherein the external display is configured to output a video signal during a reduced operating state of the host processing system.

18. The information handling system of claim 17, further comprising:

an internal display operational to display information from the host processing system and the remote processing system when a lid of the housing is in an open position;

wherein the external display is configured to be enabled when the lid of the housing in a closed position; and

wherein the external display is operational to output video of the host processing system and the remote processing system.

19. The information handling system of claim 18, further comprising:

a video multiplexer configured to multiplex a first video signal output from the host processing system with a second video signal output from the remote processing system; and

an input interface operably coupled to the external display including;

a first input configured to access a resource of the host processing system; and

a second input configured to access a resource of the remote processing system.

20. The information handling system of claim 17, wherein the remote processing system is configured to detect when a lid of the housing is in a closed position and to initiate outputting a video received by the remote processing system to the external display.
