For Samsung, Defining designed the FX, a dual display Notebook PC that offers innovative usability in a mobile computing environment. The FX has two built-in displays, creating a multi-screen experience that allows users to use both screens simultaneously when needed. Users slide open the rear display to use it as a dual monitor in a mobile environment. The design of FX was born out of the problem that while dual monitors are becoming more common in office environments, the same experience is not possible in mobile environments. FX solves this problem perfectly. FX is designed in two types, one that slides left and right and one that slides up and down, allowing you to use two screens simultaneously. Defining's FX is a prime example of product innovation by design.
