Abstract

A graphic display module operating on a first device prepares graphic data to be displayed on a wirelessly connected display adapter that includes graphics processing capability. The display adapter transmits metadata to the graphic display module that includes the graphic processing capabilities of the display adapter. The graphic display module uses the metadata, and possibly the available bandwidth, to selectively delegate graphic processing tasks to the display adapter.

Claims

1. A device to produce graphics data which is capable of being displayed on a display device, the device comprising:

a processing unit;

a wireless communication port coupled to the processing unit;

a graphic display module that is executed by the processing unit, the graphic display module causing the processing unit to perform operations including—

receiving information from a wirelessly connected display driver device, the information including graphic processing capabilities of the display driver device;

obtaining graphics data;

creating, based at least in part on the received graphics processing capabilities of the display driver device, instructions for processing the graphics data with the display driver device; and

causing the wireless communication port to transmit, to the display driver device, graphics data and the instructions.

2. The device of claim 1, wherein the graphic display module causes the processing unit to perform operations further including receiving a request to display the manipulated graphics data on a visual display unit coupled to the display driver device.

3. The device of claim 1, wherein the information received from the display driver device further includes a rotational orientation of a visual display unit.

4. The device of claim 3, wherein the instructions transmitted to the display driver device further instruct the display driver device to manipulate the transmitted data using the graphic processing capabilities of the display driver device to provide a correct rotational orientation of the data for display on the visual display unit.

5. The device of claim 1, wherein the graphic display module causes the processing unit to perform operations further including receiving one or more graphic layer objects to create a visual display on a visual display unit coupled to the display driver device by manipulating the one or more graphic layer objects.

6. The device of claim 5, wherein the instructions transmitted to the display driver device are based at least in part on the one or more graphic layer objects and the information from the display driver device, and wherein the instructions further instruct the display driver device to perform at least a portion of the manipulations of the one or more graphic layer objects to create the visual display on the visual display unit coupled to the display driver device.

7. The device of claim 1, wherein the instructions transmitted to the display driver device are further based on an available bandwidth on the wireless communication port.

8. The device of claim 7, wherein the graphics data transmitted to the display driver device is compressed based at least in part on the available bandwidth on the wireless communication port and the graphic processing capabilities of the display driver device.

9. A method of producing graphic data capable of being displayed on a display device, the method comprising:

receiving information from a wirelessly connected display driver device, the information including graphic processing capabilities of the display driver device;

obtaining graphics data;

creating, based at least in part on the received graphic processing capabilities of the display driver device, instructions for processing the graphics data with the display driver device; and

transmitting, to the display driver device, the graphics data and the instructions.

10. The method of claim 9, further comprising receiving a request to display the manipulated graphics data on a visual display unit coupled to the display driver device.

11. The method of claim 9, wherein the information received from the display driver device further includes a rotational orientation of a visual display unit.

12. The method of claim 11, wherein the instructions transmitted to the display driver device further instruct the display driver device to manipulate the transmitted data using the graphic processing capabilities of the display driver device to provide a correct rotational orientation of the data for display on the visual display unit.

13. The method of claim 9, further comprising receiving one or more graphic layer objects to create a visual display on a visual display unit coupled to the display driver device by manipulating the one or more graphic layer objects.

14. The method of claim 13, wherein the instructions transmitted to the display driver device are based at least in part on the one or more graphic layer objects and the information from the display driver device, and wherein the instructions further instruct the display driver device to perform at least a portion of the manipulations of the one or more graphic layer objects to create the visual display on the visual display unit coupled to the display driver device.

15. The method of claim 9, wherein the instructions transmitted to the display driver device are further based on an available bandwidth on the wireless communication port.

16. The method of claim 15, wherein the graphics data transmitted to the display driver device is compressed based at least in part on the available bandwidth on the wireless communication port and the graphic processing capabilities of the display driver device.
