DISPLAY HEAD ASSEMBLY

Few Integrators, Value-Add Resellers or Custom Engineering Houses can boast having over 40 years of experience in the flat panel display marketplace like General Digital. Still fewer offer the full spectrum of integration expertise and services under one roof.

While General Digital is perhaps best known for its myriad of standard turnkey product offerings and “build-to-order” custom monitor solutions, no product epitomizes our integration prowess as well as our Display Head Assembly (DHA) enhanced screens.

  • Overview

    Key Features

    • Core flat panel displays from 6.5″ to 65″ (inquire about all available sizes)
      • Enhanced by General Digital with countless value-add products and services
    • Design, manufacture and integration of:
      • Single board computers
      • Various controllers
      • Other electronics and PCBs
      • Enclosures and bezels
      • Various overlays
      • Much more
    A Solid Foundation Upon Which to Build
    photo collage

    General Digital defines a Display Head Assembly (DHA) as a composite consisting of a flat screen display that has been selected specifically for the application requirements, and one or more of our value-add products and services.

    Display Head Assemblies are intended for customers who will provide some level of design integration on their own. Rather than purchase a turnkey monitor, they elect to procure a monitor subset featuring a flat panel display and one or more value-add products and/or services. The DHA readily allows customers to protect their proprietary technology, utilize their skill sets to their fullest economic and performance advantage, and specify only the products and services that we have mastered and uniquely provide.

    LCD Selection

    The DHA begins with selection of a flat panel display that best meets the electrical, optical, physical and environmental requirements of the application. Other factors include:

    • pricing
    • availability
    • length of product life cycle

    In the event that an off-the-shelf display does not meet all of the necessary requirements, we have the ability to enhance the standard performance with our value-add and integration services.

    Selection of the target core OEM display can be predetermined by the customer, or recommended by General Digital. We may suggest an “off-the-shelf” OEM panel, the enhancement of an OEM panel or a value-add panel that we have already engineered and tested (such as the LED-enhanced, sunlight readable and NVIS-compatible panels shown in our Enhanced Displays Line-Up Sheet).

    General Digital has the in-house capability to quantify any enhanced display’s performance optically (e.g., brightness, contrast, reflectivity, NVIS compatibility), thermally (e.g., temperature chamber), electrically and for emissions, as well as other mechanical or miscellaneous testing.

    Enhancement Choices

    After the display has been properly selected, General Digital can embellish the performance of the flat screen panel with a multitude of optical, electrical or mechanical overlays in the form of products and services, as shown in the graphics below.

    Front View

    Rear View

    Bezel Choices

    After the elements of the Display Overlay Assembly have been selected and completed, General Digital can further embellish the DHA by adding optional bezel enhancements, as shown in the graphic below.

    Rear Enclosure Choices

    General Digital can also integrate electronic and mechanical options in a rear enclosure. We can accommodate specialty needs with commercial-, industrial- and military-grade components, as shown in the graphics below.

    Other Options & Accessories

    photo of display options

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

    • Programmable backlight/thermal controllers for optimal brightness/temperature conditions
    • Rack mount keyboards and desktop keyboards with integrated pointing device
    • Smart Card (CAC) readers
    • Video/serial/power cables
    • Fiber optics
    • Custom controls
    • Private labeling
    • Extended warranties

    Please consult a Sales Engineer to discuss your specific needs or ideas.

    Configuration Control for Extended Life Cycle

    We at General Digital are completely responsible for the design and construction of our products, allowing us to maintain nearly total control of their future. To that end, we gladly offer our engineering services to customers who require special customization of our devices to meet their commercial, industrial, marine or military requirements.

    Our experience supporting Department of Defense programs has taught us the value of designing products with foresight so that they can be manufactured, serviced and upgraded for many years.

    Though the market introduces new innovations and product upgrades at an alarming rate, our product management team knows the importance of proactive customer notification. Thus, we can offer product adaptation with similar or equivalent performance before designs become obsolete, thereby extending the product life cycle.

    Please consult a Sales Engineer for additional details.
