Graphic for display enhancement servicesThe unique design of the Rack Mount Hinge yields an ultra-low profile enclosure of one vertical rack unit (1U = 1.75") when stowed (2U = 3.50" for the 20" model). 

When deployed from the rack drawer, the monitor pivots up or down 90° (factory configured) for operation and extends only about 4 to 6 inches from the rack chassis. This increases operator workspace, which is especially important in space-constrained environments.

Additionally, the display can easily be located at eye level within your 19" RETMA rack to optimize ergonomics.


We work with you to configure and build your Rack Mount Hinge monitor to meet your precise needs. Furthermore, we offer a wide range of practical options for you to custom design your unit.

What truly separates our Rack Mount Hinge Series from the rest of the crowd is its ability to provide you with the following benefits:

  • Rack Mount Hinge offers several display sizes/resolutions from 15" to 20".
  • Configuration flexibility with a wide variety of LCDs, video controllers, display overlays, pointing devices, power supplies, slides and enclosures to meet specific requirements.
  • Flawless operation in harsh and demanding environments; e.g., extremes of temperature, humidity, shock, vibration.
  • Long product life cycle. We can repair and/or replace defective or degraded parts with like or equivalent, compatible electronics or mechanical parts.
  • Designed, manufactured, tested and serviced in the U.S.A.
  • Custom configurations with optional components:

General Digital’s rugged aluminum enclosures are designed to withstand the rigors of commercial, industrial and military environments alike.

The enclosures are irridite coated (conductive anodized), providing protection from corrosion and improving the shielding properties where metal parts make contact with one another. All external surfaces are finished with a durable black powder coat.

They offer superior configuration flexibility, thus eliminating extensive redesign while still permitting the incorporatation of contemporary technological advances.


Close-up of display hingeCustom designed slides allow the Rack Mount Hinge to conveniently slide in and out of a 19" RETMA rack while occupying only 1U of rack space (2U for the 20" model). The slides also allow the display head to pivot up or down 90 degrees (factory configured) for optimal operation. The Rack Mount Hinge requires no assembly or disassembly to operate—simply pull out and pivot 90° to use. 

This model is specially suited to space-constrained environments, as it extends only 4"–6" from the rack chassis when in use.


All of the interfaces (video, serial, power, etc.) utilize shielded locking connectors that are (typically) located on the rear of the enclosure.

General Digital protects your display against direct contact with foreign objects by overlaying the liquid crystal display with a pane of one (or more) of the following options:

  • Optical-grade, antiglare-etched or antireflective-coated glass
  • Chemically-strengthened and tempered glass
  • Laminated glass vandal shield
  • Polycarbonate or acrylic plastic protective overlay
  • Touch screen
  • Optical bonding
  • Optically clear EMI/RFI ITO-coated glass shield

To provide even greater protection, a sealed gasket is installed between the display and bezel, as well as between the bezel and protective overlay, to guard the monitor’s electronics from dust, liquids (e.g., spilled drinks) and other debris.

Display and backlight types
General Digital can integrate virtually any LCD display size/resolution, from almost any panel manufacturer (OEM), into our enclosures. To assist in selecting the right panel for your application requirements, we have provided a list of commonly used or recommended panels for standard/low luminance, high brightness, sunlight readable and NVIS compatible needs.

New display models are constantly being introduced to the market by the LCD manufacturers, making it extremely difficult for us to maintain a comprehensive list. For this reason, we encourage you to speak with a Sales Engineer to share your price and performance objectives, so we can assist you in making the best display selection.

Standard Displays

General Digital has provided a sample listing of some common transmissive displays that are not sunlight readable. Typically, these displays are suitable for applications that are not going to require specialty functionality, such as sunlight readability or NVIS compatibility, and for customers with cost-sensitive budgets.

Standard brightness display types
LCD backlight produces sufficient luminance for use in office, shaded and low ambient/darkness light levels. However, luminance is insufficient to overcome reflected light for use in direct sunlight.

Tranmissive Enhanced Displays

This type of technology boosts the efficiency of the backlight’s light utilization and minimizes surface reflection of ambient light. It is a transmissive LCD module that produces high contrast images, even in bright outdoor light and direct sunlight. These displays feature a wider color reproduction range than reflective LCDs. Featuring an LED backlight, these displays consume very little power and produce very little heat, making them ideal for integration into fully sealed enclosures, which are devoid of ventilation holes and cooling fans to dissipate heat. They also provide the additional benefit of a wide operating/storage temperature (as great as -30°–85° C), so that they can endure exposure to greater internal ambient temperatures.

As a design note, we have found that these panels work best when coupled with an overlay that has an antireflective (AR) coating. Overlays that inhibit transmissivity (e.g., resistive touch screen) or have antiglare (AG) coatings will significantly reduce the panel’s performance in high ambient lighting conditions. Since transmissive displays produce greater brightness from their LED backlights than traditional transflective displays, they are regarded as a better outdoor solution, as they can generate high contrast in total darkness, in direct sunlight or on a cloudy/hazy afternoon.

Transmissive-EVT High Brightness Display Types
T-EVT technology uses the high brightness/efficiency LED backlight as a light source while minimizing the surface reflection of ambient light. The result is an LCD that produces high contrast images even in bright outdoor light or direct sunlight.

GenFlective™/Transflective Displays

This type of panel incorporates a highly reflective backlight that reflects the ambient lighting back out of the display to enhance its native brightness produced by its active backlight. Like the Transmissive-Enhanced View Displays, GenFlective panels work best when coupled with an AR-coated overlay. They are least effective with overlays that retard the light transmission (e.g., resistive touch sensors) or have a matte finish.

GenFlective/Transflective High Brightness Display Types
T-EVT technology uses the high brightness/efficiency LED backlight as a light source while minimizing the surface reflection of ambient light. The result is an LCD that produces high contrast images even in bright outdoor light or direct sunlight.

Sunlight Readable/NVIS Compatible Displays

These displays feature a value-add backlight, typically made from high efficiency LEDs. These displays produce significant active luminance. Often, the peak luminance is limited by internal ambient temperature constraints or must be connected to an intelligent backlight controller and thermal sensor that will automatically reduce brightness/power to avoid over-temperature conditions or thermal shutdown. The high luminance output makes them ideal for use with a wide variety of overlays such as touch sensors, EMI filters, heaters, etc.

Sunlight Readable/NVIS-Compatible Display Types
Sunlight readable displays use a General Digital-enhanced, highly efficient, super bright/sunlight readable LED backlight to provide maximum functional brightness. The addition of surface treatments such as antireflective coatings and optical bonding reduce surface reflections and increase contrast so displays can be used in direct sunlight.

If our stock offering does not suit your needs in terms of size, fit or function, please contact a Sales Engineer and we will work with you to configure a system to your specifications. Customers can also request that we integrate one of our many LED-based sunlight readableNVIS or sunlight readable/NVIS enhanced displays into their product. These solutions provide many advantages, such as increased longevity, improved durability, higher brightness, lower power consumption and/or NVIS compatibility.


A myriad of display enhancements and services are available, such as:
