Abstract

The invention comprises systems and methods for partitioning displays, and in particular, displays of interferometric modulator displays. In one embodiment, a display system includes one driving circuit configured to provide signals based on video data intended for display, and a bi-stable display comprising an array having a plurality of bi-stable display elements. The array is configured to display video data using signals received from the driving circuit, and the driving circuit is configured to partition the array into two or more fields, each field including at least one bi-stable display element, and refresh each of the two or more fields in accordance with a refresh rate associated with each field. In another embodiment, a method of displaying data on a display of a client device includes partitioning a bi-stable display of the client device into two or more fields, displaying video data in the two or more fields, and refreshing each of the two or more fields in accordance with a refresh rate that is associated with each field.

Claims

1. A communications system for server-based control of a display on a client device, comprising:

a server configured to define two or more fields of a bi-stable display of a client device, the bi-stable display having a plurality of bi-stable display elements, each field having an associated refresh rate, and the server further configured to receive display information over a communications network, and transmit video data to a client device over the communications network based on the display information,

wherein the client device is further configured to receive the video data from the server, to display the video data on the two or more fields of the bi-stable display, and to update each field using the associated refresh information.

2. The system of claim 1, wherein the display information indicates one or more characteristics of the display.

3. The system of claim 1, wherein the display information indicates a display mode.

4. The system of claim 1, wherein the display information comprises information indicating where the video data should be rendered on the bi-stable display.

5. The system of claim 1, wherein the server is further configured to identify the video data to be displayed in each of the two or more fields.

6. A data display system, comprising:

a content server configured to provide video data to a client device in data communication with the content server, the client device comprising a bi-stable display that is configurable to display data in two or more fields, each field being associated with at least one bi-stable display element,

wherein each field of the bi-stable display can be refreshed at its own refresh rate.

7. The data display system as in claim 6, wherein at least one of the fields is separately addressable by the content server.

8. The data display system as in claim 6, wherein the content server comprises a processor and a software module, the software module being associated with the received data.

9. The data display system as in claim 6, wherein the client device is configured to communicate characteristics of the display to the content server.

10. The data display system as in claim 6, wherein the two or more fields comprise a first field and a second field, and wherein the bi-stable display comprises a first set of interferometric modulators and a second set of interferometric modulators, the first set of interferometric modulators being associated with the first field and the second set of interferometric modulators being associated with the second field.

11. The data display system as in claim 10, wherein at least one interferometric modulator from the first set of interferometric modulators is assigned to the first set of interferometric modulators and to the second set of interferometric modulators.

12. The system of claim 6, wherein the server is further configured to source video data to be displayed in each of the two or more fields of the bi-stable display of the client device.

13. A communications system for server-based control of a display on a client device, comprising:

a client device comprising a bi-stable display having a plurality of bi-stable display elements, the client device being configured to transmit display information over the communications network to a server,

wherein the server is configured to define two or more fields of the bi-stable display, each field having an associated refresh rate, and the server is further configured to transmit video data to the client device over the communications network based on the display information, and

wherein the client device is further configured to receive video data from the server, to display the video data on the two or more fields of the display, and to update each field using the associated refresh information.

14. The system of claim 13, wherein the display information indicates one or more characteristics of the display.

15. The system of claim 13, wherein the display information indicates a display mode.

16. The system of claim 13, wherein the display information comprises information indicating where the video data should be rendered on the bi-stable display.

17. The system of claim 13, wherein the server is further configured to identify the video data to be displayed in each of the two or more fields.

18. A data display system, comprising:

a client device configured to receive video data from a content server, the client device comprising a bi-stable display that is configurable to display data in two or more fields, each field being associated with at least one bi-stable display element,

wherein each field of the bi-stable display can be refreshed at its own refresh rate.

19. The data display system as in claim 18, wherein at least one of the fields is separately addressable by the content server.

20. The data display system as in claim 18, wherein the content server comprises a processor and a software module, the software module being associated with the received data.

21. The data display system as in claim 18, wherein the client device is configured to communicate characteristics of the display to the content server.

22. The data display system as in claim 18, wherein the two or more fields comprise a first field and a second field, and wherein the bi-stable display comprises a first set of interferometric modulators and a second set of interferometric modulators, the first set of interferometric modulators being associated with the first field and the second set of interferometric modulators being associated with the second field.

23. The data display system as in claim 22, wherein at least one interferometric modulator from the first set of interferometric modulators is assigned to the first set of interferometric modulators and to the second set of interferometric modulators.

24. The data display system of claim 18, wherein the server is further configured to source video data to be displayed in each of the two or more fields of the bi-stable display of the client device.

25. A data display system, comprising:

means for partitioning a bi-stable display of a device into two or more fields, wherein the two or more fields comprise a first field comprising a first set of interferometric modulators and a second field comprising a second set of interferometric modulators;

means for displaying video data in the two or more fields; and

means for refreshing each of the two or more fields in accordance with a refresh rate that is associated with each of the two or more fields.

26. The system of claim 25, wherein the means for partitioning comprises a server.

27. The system of claim 25, wherein the means for displaying comprises a client device.
