Patent ID: 8823640

Claim:
A portable computer device, comprising: housing, holding a processor therein which runs a program that receives inputs and produces outputs, having a first display screen, and where at least some of said outputs are shown on said first display screen, said housing having at least one sensing part, that senses a proximity of another housing holding another processor and having another display screen, and where said processor runs a program from non-transitory storage that runs a program only on said first display screen in a first mode where said proximity of said another housing is not sensed to create a first output, and automatically shows said first output on only said first display screen in said first mode where said proximity of said another housing is not sensed, and to show said first output across both said first display screen and said another display screen of said another housing in a second mode where said proximity of said another housing is sensed, to create an expanded display including at least one line segment which extends from said display to said another display and is continuous across a junction between said display to said another display, and where a same line segment is displayed only on said first display screen when said proximity of said another housing is not sensed, and wherein the processor sets a first narrower aspect ratio for the display when only a single housing is detected, and sets a wider aspect ration for the display when two housings are detected and where the line segment when the two housings are detected extends over a longer distance than the line segment when the two housings are not detected.
