US Patent 7502221 Multiple-use auxiliary display

Described is a technology by which an auxiliary computing device comprising a display and/or actuator set coupled to a host computer system may be interacted with (e.g., viewed) independent of whether a main display of the host computer system is visible, e.g., whether a laptop lid or tablet lid is open or closed. In one example implementation, the auxiliary device is located above the keyboard and the main display slightly elevated on one or more pivoting supports. This effectively provides an opening in the lid through which the auxiliary device may be viewed.
