Rack-mount displays fold into 2U space

Military Rack Mount display – Bi-Fold and Tri-Fold
Everybody wants more pixels and bigger C4ISR workstation displays, especially the military when they are hunting for the bad guys. They don’t care if it’s difficult, they just want it and they want it small, light and tough. So how do you cram large LCD flat panels into a small C4ISR workstation display package that will survive rough handling and transport by military aircraft and helicopters? The C4ISR workstations and their displays are typically packaged in combination cases that can be covered and shipped anywhere around the world as needed. These combi-cases often have an option for shock-mounting the rack they enclose. Fitting a display into a 2U 19″ rack space means more space for communications systems, computer cooling systems or even, a smaller case!
The answer to the packaging and ruggedization is innovative engineering. Acme Government Systems (AGS) has just introduced a series of folding 17.3”, 19” and 23” ruggedized rack mount C4ISR workstation 2U displays that push the boundaries of how much can be stuffed into a 19” rack. Video of folding mechanism of the 23″ dual display 2U rack-mount.
Here’s an example of a dual 17.3” full HD (1920 x 1080 pixels) C4ISR workstation display unit in a 2U (3.5” high) rack mount package. This AGS-RMDDU-HD-17 provides an operator-centered set of HD dual displays that fold and stow in a very slim 2U package for transport
The AGS-RMDDU-HD-17 C4ISR Workstation 2U display above uses HD displays, which have a 19:9 form factor. This is the newest display form factor and is used in all HD television sets and most new desktop monitors and higher end laptop computers. In some cases the military has written its C4ISR command and control software to display on a 4:3 aspect ratio display in XGA (1024 x 768) or SXGA (1280 x 1024).
Below (courtesy of Wikipedia) are charts of the various display resolutions and conventions. The trend is towards more density and larger display sizes are the requirement in C4ISR workstations continues to push more data to the user. See http://en.wikipedia.org/wiki/Display_resolution
For these 4:3 legacy applications, Acme Government Systems www.acmemilspec.com has created two C4ISR Workstation display systems, the AGS-RMDDU-SX-19, a dual folding display (Bi-fold) in a 2U form factor and the AGS-RMTDU-SX-17 a triple folding display (Tri-fold) in a 3U form factor.
Display systems from Acme Government Systems feature a range of native inputs from analog VGA, to DVI to DisplayPort. HDMI inputs can be accommodated via a converter on the DVI port.
All 2U displays feature pull out backlit keyboards that have variable intensity backlighting to adjust to low light environments. The keyboards have an integral resistive touchpad for cursor control and available USB feed through ports for the connection of other devices, like an optical mouse or CAC card reader.
The military displays are constructed of a metal chassis and display housing that is designed and tested to meet the transportation and operation requirements of MIL-STD-810G for operating shock, transport shock, operating vibration, cargo drop etc.
19″ Rack Mount Specifications
What is a rack Unit (“U”)?
A rack unit, or U is a unit of measure that describes the height of equipment designed to mount in a 19″ rack. The 19-inch (482.6mm) dimension is the width of the equipment mounting frame in the rack including the frame; the width of the equipment that can be mounted inside the rack is less. One rack unit is 1.75″ (44.45mm) high. 2U displays are therefore 3.5″ high. If we are going to be completely accurate, the front panel is defined as (xU x 1.75″) – 1/32″ to allow for a slight gap between panels.
