The first and/orsecond display controllers - With respect to the
second display controller 24, thesecond display controller 24 retrieves the content stored in thememory 32, and converts that data to VESA (Video Electronics Standards Association) standards for VGA output, wherein these standards are incorporated by reference. In performing this conversion, thesecond display controller 24 generates a defined resolution, timing diagram, timing sequence, and the period for transferring data following the VESA standards to display the content on theexternal display device 26. The converted data can be transferred via a cable connected to theexternal display device 26. Various VESA display resolutions can be supported through the cable to theexternal display device 26. - Generally, a VGA connector and video connectors of a television (e.g., RCA connectors, S-Video connectors, and component connectors) have separate form factors, thus requiring separate cables to connect to these connectors. Furthermore, these connections can be implemented using different standards, thereby requiring the usage of special cables for the connectors. For instance, if a display controller outputs a signal for an S-video connection, this cannot work for a VGA format since VGA cables have more wires than the S-video cable and are governed by different standards.
- In an embodiment of the invention, a single cable can be used to connect to various types of audio/video connections of an external display device. Software can configure the device to correctly output the correct signals for a particular connection. The cable can be physically similar to a USB-like connector and cable.

Once the type of connection is determined, the software on the mobile phone device can initiate transmission of the video data in accordance with the respective standards for that connection.
- Generally, VGA requires more wires than TV out since TV out may need one wire, two wires (s-video connection), or three wires (component connection). Therefore, the TV out wires can be mapped to the wires used for a VGA connection in order to support various TV out connections through a single cable.

If it is a VGA connection, then there may be no need for a mapping since the wires can be configured for VGA video output as the default setting. HW can also detect whether or not the cable is plugged in to theexternal display device 26. - In addition to the mobile phone device automatically sensing the type of connection to the
external display device 26, the user of the mobile phone device can also select which type of audio/video connection to output the displayable content from the mobile phone device to theexternal display device 26. - The mobile phone device can automatically sense the video connection attached to it.

The SW on the mobile phone device can determine the type of connection used and send video data in accordance with the respective standard for that video connection. - When a user plugs in the mobile phone device to the
external display device 26 via an appropriate connector, the mobile phone device can automatically transmit data to theexternal display device 26 in accordance with the respective video standard. For instance, if the user plugs in the cable into the I/O connector of the mobile phone, and on the other end of the cable is plugged into an LCD monitor that supports 1024×768 via a VGA connection on the monitor. The mobile phone device can automatically detect that the attached external display device is a monitor, and switch to the appropriate resolution. Alternatively, if the user instead plugs the cable into a composite video source, the mobile phone device will automatically determine that the device is a television and output the appropriate video via the composite video connection. - This can also work for a docking station for the mobile phone device.

Next, theprimary processor 10 controls thegraphics accelerator 6 to generate UI frames, which are also stored in thememory 32 via thememory interface 30. Theprimary processor 10 controls thegraphics accelerator 6 to merge the UI frames and document frames in thememory 32 into the final display frames. Theprimary processor 10 controls thesecond display controller 24 to fetch the generated display frames and display the data through the VGA interface (or other video interface, e.g., HDMI, DVI, etc.) to theexternal display device 26, e.g., a projector. - The systems and methods of this invention can be extended to support the capability of using a mobile phone device to transmit recorded video to an
external display device 26. Alternatively, the mobile phone device can be used to transmit real-time video to anexternal display 26, similarly to a surveillance system. Another use can be to view a movie on anexternal display device 26, driven by the mobile phone device, wherein the movie can be retrieved from the Internet or other network connected to the mobile phone device via theRF transceiver 36. - In yet another embodiment of the present invention, the internal
primary display 2 can be a touch screen for receiving user input. Thus, the user can directly operate video games, document presentations, or other applications by inputting commands onto the touch sensitiveprimary display 2. - While the present invention has been described with reference to certain preferred embodiments or methods, it is to be understood that the present invention is not limited to such specific embodiments or methods. Rather, it is the inventor's contention that the invention be understood and construed in its broadest meaning as reflected by the following claims. Thus, these claims are to be understood as incorporating not only the preferred methods described herein but all those other and further alterations and modifications as would be apparent to those of ordinary skilled in the art.
