Outstanding development of wireless communication technology magnified the mobility as the core value of note PC. Our task was to design the product as slim and light as possible while securing its function. Our solution was to arrange ODD and Keyboard, two parts that decide the thickness of product, in parallel rather than a typical layout of lamination. Top-Loading ODD was used and Keyboard was located at the bottom of the product. Quite challenging design concept of this excited us and we had to deal with many internal questions but we eventually succeeded in Samsung Sens X1 commercialization. ATIV Tab 5 is tablet and note PC at the same time; it’s a hybrid product. Hard type keyboard unit designed for easy detachment provides the same usability as note PC. Built-in battery ensures long durability of use even in mobile environment. Users can conveniently use this product as a tablet PC or a notebook PC, depending on their purpose. Appearance of ATIV Tab5 Design has opened the age of Hybrid PC.
