Abstract: The invention was imagined as a response to the problems associated with limited screen space of portable computing devices (i.e. laptops, PDAs, etc.). Because of issues of portability, size and weight these devices have been limited to a single, undersized screen in which relatively small amounts of information can be displayed at the same time. Though there exists some means of attaching secondary displays to the devices, there exists no practical way of taking these secondary devices with the user (i.e. allowing for complete portability of all aspects of the devices). The invention rests on the premise of creating a new system that allows for the portability of secondary display devices to solve the issues described in the background section. By placing a secondary screen behind the primary screen of the device, while still maintaining the portability of the original portable computing device, we solve the above problem.

Abstract: The invention in a response to the problems associated with limited screen space of portable computing devices (i.e. laptops). Because of issues of portability, size and weight these devices have been limited to a single, undersized screen in which relatively small amounts of information can be displayed at the same time. Though there exists some means of attaching secondary displays to the devices, there exists no practical way of taking these secondary screens with the user. The invention rests on the premise of creating a new system that allows for the portability of secondary display devices. By placing a secondary screen on a hinge in front of the primary screen, while still maintaining the portability of the original portable computing device I solve this issue. The concept resembles the concept similar to a door. Thus, the secondary screen(s) shall be known as the “door screen(s)” and the primary screen shall be known as the “doorway screen”.
