Abstract: A portable electronic device is disclosed. The portable electronic device includes a housing. The portable electronic device also includes computing electronics that are supported by the housing. The computing electronics include a processor, a display controller coupled to the processor, and memory coupled to the processor. The portable electronic device disclosed also includes an expandable display coupled with a display controller. The expandable display is expandable from a first size to a second size. The first size is different than the second size. A sensor is coupled to the processor. The sensor is configured to provide a signal representative of the size of the display.

Abstract: A display system for a handheld computing device is disclosed. The display system includes a processing unit having a first communication port, and a visual display unit separable from the processing unit. The visual display unit further includes a visual display, and a second communication port. The display unit can be expanded from an initial or storage state to present a larger visual display size. Further, the first communication port providing communication with the second communication port.

Abstract: A display system is disclosed. The display system includes a processor. The display system also includes a first display device having a first display surface and receiving display data from the processor. The display system also includes a second displayed device having a display area smaller then the first display device and moveable over the surface of the first display device. The display system also includes a sensor in communication with the processor and communicating location data to the processor. The location data is representative of the relative location of the first display to the second display. Further still, the display system includes a program running on the processor and providing display data to the first and second display devices. The display data is provided to the second display device based on the location data.

Abstract: A display system is disclosed. The display system includes a processor and a first display device having a first display surface and receiving display data from the processor. The display system also includes a second display device having a display area smaller than the first display device and moveable over the surface of the first display device. The second display device is either partially transparent or partially translucent. The display system also includes a sensor in communication with the processor and communicating location data to the processor. The location data is representative of the relative location of the first display to the second display. A program is configured to run on the processor and provides display data to the first and second display devices such that the display data prior to the second display device is based on the location data. A user of the system views a composite three-dimensional image when viewing the second display.
