LG Triptych: Concept Mobile converted to Tablet

Recently the designer Edward Hale, published some photos of a concept phone by LG, the Triptych, which can be converted into tablet.
Although it sounds similar to the Echo, it announced the Sprint and Kyocera for your mobile / tablet dual touchscreen, the two companies could take some lessons from planning Hale. The Triptych does the Echo seem a little funny. Fortunately for them, LG is still busy with the first tablet of the  G-Slate  (Optimus pad). 
Triptych O design has a very slim body phone with two additional screens behind the phone and unfold to form the screen tablet. Imagine how terrible it would be if using AMOLED technology for this. 
It is also interesting to consider what functions will be used, since it can switch between phone and tablet.
