Thumbnail graphic of Enhanced Displays Line-Up SheetFew 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 enhanced screens.

 

A SOLID FOUNDATION UPON WHICH TO BUILD

Display Head Assemblies can be used in virtually any environment

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

Image of displayThe 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.

CONFIGURATION CONTROL FOR EXTENDED LIFE CYCLE

Photo of mechanical drawingWe 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.

    Optical Characterization Services (2:16)

    Unlike your phone, a display’s position cannot easily be adjusted to increase readability in direct sunlight. General Digital’s Optical Characterization Services take the guesswork out of quantifying how your display will perform under sunlight conditions. The following video explains the process in detail.
