The Taiwanese manufacturer said the prototype could be used as a conventional laptop, a multimedia hub or an an e-book reader.
"The dual panel offers a flexible working space in which users can adapt to suit their prevailing usage scenarios, for example adjusting the size of the virtual touchpad and keyboard," said Asus.
The use of the touchcreen provides an input mechanism that's both flexible and intuitive, according to Asus. The company said the system could be controlled using hand gestures, handwriting recognition and multi-touch.
However, by disabling the software-based keyboard, the laptop can also be turned into an e-book, which can be held like a conventional book in which pages can be moved through touch or gestures.
Also, the two panels could be combined to form a larger display for watching widescreen movies.
