Forth Dimension Displays Limited (ForthDD) has headquarters in Dalgety Bay, Scotland and offices in Valencia, USA, and Berlin, Germany. The company designs, develops and manufactures single chip microdisplays used in the demanding near to eye (NTE) training and simulation systems, HD video camera viewfinders, medical imaging systems and virtual reality and head-mounted displays.

ForthDD's proprietary technology allows imaging to be performed temporally (Time Domain Imaging, TDI) without subpixels or tilting micro-mirrors. TDI is extremely fast-switching and 100% digital, providing 24-bit full colour images capable of handling high-speed motion and without artefacts. ForthDD's single chip imagers are especially well-matched to the new solid state LED and laser diode light sources and provide very high native resolution: SXGA /720p and UXGA/1080p.

In September 2004 ForthDD (then called CRLO Displays Ltd) raised a Series ‘A’ financing round of $19 million led by Amadeus and Doughty Hanson. Barak Maoz is a non-executive director of ForthDD
