  • This application claims the benefit of U.S. provisional patent application Ser. No. 61/446,027, filed Feb. 23, 2011, which is hereby incorporated by reference.
    • BACKGROUND
  • Computing environments continue to evolve. One of the latest evolutionary steps is the use of more than one display screen to view data generated by a computer system. For example, a computer designer may use one display to show a schematic of a portion of an electronic device and another display to show a layout of that portion of the electronic device.
  • The inclusion of multiple displays is driven by many factors. For example, computing tasks are becoming more complicated. These tasks are being handled by more powerful programs and computing resources, which are able to provide multiple graphics images. Also, the costs of such displays and associated hardware have been reducing as the quality has been increasing. Moreover, users are becoming more skilled and are able to handle more data.
  • These displays may be of various types. For example, they may be dedicated displays that are separate from computing devices. They may also be displays that are integrated into a computing device, such as a desktop, all-in-one computer, laptop, netbook, tablet, ultrabook, or other such device.
  • It is often fairly straight-forward to use a dedicated display as a second display. Dedicated displays are configured to accept not only video information from an external source, but control signals as well. These control signals may include signals to adjust brightness, audio levels, resolution, and others.
  • Display panels that are integrated with, or are connected to, other devices may not be so flexible, however. These displays may be configured to communicate these signals with the computing devices of which they are a part. They may not be configured to accept signals from external computing devices. As such, these displays may not be as suitable for use as a second display device.
  • Accordingly, what is needed are circuits, methods, and apparatus that provide displays that may be used as secondary display devices.
    • SUMMARY
  • Accordingly, embodiments of the present invention may provide circuits, methods, and apparatus that provide displays that may be used as secondary display devices.
  • An illustrative embodiment of the present invention provides a circuit that may be placed in a communication pathway between a host computer and a second display device external to the host computer.

    •  DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
  • FIG. 1 illustrates a computer system that may be improved by the incorporation of embodiments of the present invention. This computer system may be used to provide a user with a computer system having two displays. While two devices that include a display are shown in this figure, embodiments of the present invention may be used in computer system having three or more devices having displays. This figure, as with the other included figures, is shown for illustrative purposes and does not limit either the possible embodiments of the present invention or the claims. It should also be noted that while embodiments of the present invention are well-suited to Thunderbolt systems that convey DisplayPort AUX and video data, other embodiments of the present invention may be used to convey other signals consistent with other standard and proprietary protocols, such as High-Definition Multimedia Interface (HDMI) signals, or other signals consistent with other protocols that may be currently under development, or may be developed in the future.
  • In this example, host computer 110 may be in communication with second display device 130 over cable 120. Host computer or device 110 may be a desktop computer, all-in-one computer, laptop, netbook, or tablet computer, ultrabook, or other computing device. Second display device 130 may be a desktop, all-in-one computer, laptop, netbook, or tablet computer, ultrabook, or other computing device. In this particular example, host computer 110 is a laptop computer having display 112, while second display device 130 is an all-in-one computer that includes display 132, keyboard 134, and mouse 136.
  • Again, host computer 110 may be in communication with second display 130 over cable 120. Cable 120 may be a DisplayPort cable, Thunderbolt cable, or other appropriate cable. Cable 120 may be used by host computer 110 to provide video signals to second display 130. Cable 120 may also be used by host computer 110 to provide communication signals to, and receive communication signals from, second display 130. Examples of how this may be done are shown in the following figures.
  • FIG. 2 illustrates a block diagram of a portion of a computer device according to an embodiment of the present invention. This computer device may be used as, or associated with, a second display, such as second display 130 in FIG. 1, or as second displays in other embodiments of the present invention.
  • This figure includes connector receptacle 210, switch 220, DisplayPort output 230, display panel 240, interface circuit 250, and CPU and memory 260. Connector receptacle 210 may be a DisplayPort or Thunderbolt compatible connector receptacle. Connector receptacle 210 may receive and provide DisplayPort signals 212 over a thunderbolt connection. Connector receptacle 210 may provide DisplayPort 212 signals to switch 220. DisplayPort signals 212 may include auxiliary or AUX signals 214 and video signals 216. When both AUX signals 214 and video signals 216 are present between connector 210 and switch 220, the signals may be sent together on a common electrical connection, or they may be sent in parallel on two electrical connections, as shown in the figure. Switch 220 may provide auxiliary signals 224 and 222 to interface circuit 250 and DisplayPort output 230. Switch 220 may also provide video signals 226 to DisplayPort output 230. DisplayPort output 230 may provide auxiliary signals 232 and video signals 234 to display panel 240. Interface circuit 250 may provide auxiliary signals 252 to CPU and memory 260. CPU and memory 260 may provide signals, such as I2C signals 262, to display panel 240.
  • Again, a host computer or device may provide video signals to display panel 240. An example of this is shown in the following figure.
  • FIG. 3 illustrates a path for video signals in a portion of a computer device according to an embodiment of the present invention. Video data may be received over DisplayPort connection 212 by connector receptacle 210. Video signal 216 may be provided by connector receptacle 210 to switch 220. Switch 220 may provide video signal 226 to DisplayPort output 230. DisplayPort output 230 may provide video signals 234 to display panel 240. Display panel 240 may then display video data.
  • The video signal 226 received by DisplayPort output 230 may be arranged as DisplayPort data. DisplayPort output 230 may remove excess data and provide a video signal 234 to display panel 240. For example, video data to be displayed may be removed from DisplayPort, Thunderbolt, or other types of packets by DisplayPort output 230 or other associated circuitry.
  • In this example, switch 220 may switch video data to display panel 240 via DisplayPort output 230. Switch 220 may also provide AUX data to interface circuit 250. An example is shown in the following figure.
  • FIG. 4 illustrates a signal path for an interface circuit to receive auxiliary data according to an embodiment of the present invention. This auxiliary data may be received as part of DisplayPort signal 212 by connector receptacle 210. Auxiliary data 214 may be received by switch 220. Switch 220 may provide auxiliary data 224 to interface circuit 250.
  • This auxiliary data may be various types of data. For example, auxiliary data 214 and 224 may include signals to adjust display panels settings such as audio level, screen resolution, contrast, brightness, and others. These signals may be other types of signals, for example, signals provided by the panel indicating a present state of these settings, security, identification, and authorization signals.
  • Once interface circuit 250 receives auxiliary data 224, it may handle this data in one of a number of ways. For example, interface circuit 250 may ignore this auxiliary data. Specifically, various display panels 240 may understand one of a number of versions of a command. A host device may send each of these versions to interface circuit 250. Interface circuit 250 may then forward only the appropriate version to display panel 240. In other examples, interface circuit 250 may alter, substitute, or pass auxiliary data to display panel 240 without modification. An example of this is shown in the following figure.
  • FIG. 5 illustrates a signal path for an interface circuit to provide auxiliary data to a display panel according to an embodiment of the present invention. In this example, interface circuit 250 may provide auxiliary data 224 to switch 220.
