You are traveling into the Forth Dimension. The company's name celebrates its four-dimensional (i.e., time-based) video display devices, as well as its location on Scotland's scenic Firth of Forth waterway. Forth Dimension Displays (FDD) supplies high-resolution, near-to-eye microdisplay used in night vision systems, video camera viewfinders, medical imaging systems, and flight training simulators. The company is also adapting its ferroelectric liquid-crystal-on-silicon technology for use in gaming and other home entertainment applications, as well as in digital film printing and data storage. FDD has a support office in Germany, and sales offices in California and Japan. The company was acquired by Kopin in early 2011.
