Abstract

A display device (10) comprises an input/output channel for receiving data from a source and at least one sensor (36) operable to obtain sensor data on the display device (10). Selected ones of the or each sensor (36) are arranged to operate in response to the display device (10) receiving a request in the data from the source via the input/output channel, and the display device (10) is arranged to output the sensor data obtained by the or each sensor (36) to the source via the input/output channel. A system for monitoring at least one property of such a display device (10) comprises a monitoring unit (32) which is connectable to the one or more sensors (36) via the input/output channel to provide the request and receive the sensor data from the one or more sensors (36). The system can thereby monitor at least one property of the display device (10).

Claims

1. A display device comprising:

an input/output channel for receiving data from a source; and

at least one sensor operable to obtain sensor data on the display device, at least selected ones of the or each sensor being arranged to operate in response to the display device receiving a request in the data from the source via the input/output channel;

the display device being arranged to output the sensor data obtained by the or each sensor to the source via the input/output channel.

2. A display device according to claim 1 further comprising a graphics subsystem in communication with the input/output channel, wherein the at least selected ones of the sensors being arranged to operate in response to the graphics subsystem receiving the request in data from the source.

3. A display device according to claim 2 wherein the graphics subsystem includes an A/D converter.

4. A display device according to claim 1 wherein the input/output channel includes extended display identification formatted data.

5. A display device according to claim 1, further comprising a sensor controller, the sensor controller being arranged to monitor the input/output channel for the request and selectively control one or more of the sensors in dependence on the request.

6. A display device according to claim 1, wherein the or each sensor is operable to obtain respective data about a property of the display device selected from a list comprising:

haptic feedback, backlight brightness, backlight inverter current, ambient light, touch overlay, touch controller, shock, internal temperature colour gamut and user proximity.

7. A display device according to claim 1, further comprising a device controller operable to control at least one property of the display device, the device controller being arranged to operate in response to the display device receiving a request to control the at least one property of the display device via the input/output channel.

8. A display device according to claim 7 wherein the at least one property is selected from:

backlight power and backlight brightness.

9. A display device according to claim 7, wherein the device controller is arranged to control the property whereby the display appears non-operational.

10. A display device according to claim 9, wherein the device controller is arranged to control the property to revert the display to an operational appearance after a predetermined time.

11. A system for monitoring at least one property of a display device, the system comprising:

a display device according to claim 1; and

,

a monitoring unit;

wherein the monitoring unit is connectable to the one or more sensors via the input/output channel to provide the request and receive the sensor data from the one or more sensors to thereby monitor the at least one property of the display device.

12. A system according to claim 11, wherein the monitoring unit is encoded in a display device driver, the display device driver being arranged to be executed on a source computer connected via the input/output channel to the display for displaying content from the source.

13. A system according to claim 12, wherein the display device driver is arranged to act as an intermediary bridging between a node connected to the source on a data network and the one or more sensors, the display device driver being arranged to relay the request and sensor data between the one or more sensors and the node.

14. A system according to claim 11, wherein the monitoring unit is arranged to communicate with a data communication network.

15. A system according to claim 11 wherein monitoring unit is a display adapter.

16. A system according to claim 11, wherein the display device includes the monitoring unit.

17. A method of monitoring at least one property of a display device having at least one sensor associated with the display device and operable to obtain respective data about a property of the display device, the method comprising:

generating a request at a monitoring unit for the display device to poll the or each sensor; and

receiving data obtained by the or each sensor in response to the request.

18. A method according to claim 17 wherein the request to poll the or each sensor comprises a request to obtain respective data about a property of the display device selected from a list comprising:

haptic feedback, backlight brightness, backlight inverter current, ambient light, touch overlay, touch controller, shock, internal temperature and user proximity.

19. A method according to claim 17 further comprising controlling at least one property of the display device, in response to the display device receiving a request to control the at least one property of the display device.

20. A method according to claim 19 wherein the at least one property is selected from:

backlight power and backlight brightness.
