Forth Dimension Displays Limited
Forth Dimension Displays: A world leader in designing and manufacturing high-resolution Ferroelectric Liquid Crystal on Silicon (FLCoS) devices used as Microdisplays and Spatial Light Modulators for premium near-to-eye imagers for military, medical and virtual reality applications, as well as for structured light projection.
We provide a range of microdisplay and SLM solutions optimised for the best performance in demanding applications.
Background Information
All Digital. Time Domain Imaging (TDI). Single Chip.
The Company
Forth Dimension Displays develops, manufactures and supplies advanced microdisplays using a proprietary, fast-switching ferroelectric liquid crystal technology.
The Company was formed in September 2004 and since 2011 a 100% subsidiary of Kopin Corpoartion, a prominent microdisplay maker and system supplier to augmented reality (AR) customers.
ForthDD is located in Dalgety Bay near Edinburgh, Scotland with offices in Los Angeles, Tokyo and Berlin.
Technology and its Advantages
ForthDD's proprietary, high-speed reflective liquid crystal microdisplay and driver technology has major advantages in performance and cost.
Performance advantages: The technology is all digital. It processes images in the time domain (TDI) on a single chip, without RGB sub-pixels, separate RGB beams and optics, and without tilting mirrors.
This combination allows both amplitude and phase modulated imaging. It provides high native resolution, full 24-bit colour for showing high-speed motion. The technology is well-matched to LED and laser diode light sources.
Cost advantages: The single chip has no moving parts, so it is built using standard CMOS wafer processes. The absence of separate RGB light paths enables customers to use simpler, lower cost optics in their system integration.
A portfolio of more than seventy patents protects ForthDD's TDI technology.
Applications, Market Segments and Products
Forth Dimension Displays has an established reputation as the leading supplier of premium, high resolution microdisplays in training and simulation systems for military, aerospace and medical customers.
Further prominent applications are
- Image injection for surgical systems
- Confocal microscopy and structured illumination microscopy (super resolution microscopy)
- Digital printing and imaging systems as coded aperture imaging
- High-resolution industrial 3D metrology (AOI, SPI) and process inspection systems
- Advanced medical 3D and holographic imaging systems
ForthDD serves these segments with microdisplay chip, driver and board-level products in WXGA (1280 x 768), SXGA (1280 x 1024) and QXGA (2048 x 1536) resolution.
