Frequently Asked Questions

2) What are the different types of display products that IEE can provide?

IEE is expert in designing and manufacturing rugged displays used for different purposes and functions. These include, Multi-Function Displays (MFD), Large Area Displays (LAD), Control Display Units (CDU), Mission Displays and Custom and Retrofit displays.

3) You list specific displays by size on your website with a downloadable data sheet. Are your displays considered off-the-shelf units?

The displays shown here on the website are examples of actual displays that have been built, field-proven and deployed in the marketplace. Consider these examples that can also be further customized to meet your specific requirements.

4) What type of development timeline can I expect when working with IEE?

IEE is known for its rapid prototyping and has delivered a display in nine weeks from concept (PRD) to aircraft installation. This is accomplished with our in-house design engineers, a dedicated engineering lab and prototype assembly unit, along with other in-house test facilities and machine shop. Generally, you can expect days to mechanical samples (support for conceptual review), weeks to operational prototypes (support for software system integration), and months to field-able assets (DVT, Qualification and Transition to full-rate production).

5) What competitive advantage does IEE have and how does it benefit my company?

IEE provides a superior customer experience by offering:

• Innovative technical solutions

• Superior customer service

• Consistent on-time delivery

• Effective quality assurance

• Vertical integration of critical processes

6) What different types of touch-screen features do you offer?

Rugged military displays for cockpits typically use touch screens with specialized features designed to withstand harsh environments and facilitate ease of use. IEE offers the following touch-screen options:

1. Resistive touch screens: These screens use a flexible top layer that deforms slightly when pressed, creating a change in electrical current that is detected by the touch screen. Resistive touch screens are durable and can be used with gloves or styluses.

2. Capacitive touch screens: These screens use a conductive material, such as a person's finger, to detect changes in electrical current caused by touching the screen. Capacitive touch screens are more sensitive than resistive screens, but less sensitive with gloves or styluses.

3. Infrared touch screens: These screens use a grid of infrared sensors to detect changes in light caused by touching the screen. Infrared touch screens are highly durable and can be used with gloves or styluses.

4. Optical touch screens: These screens use a camera or other optical sensor to detect changes in light caused by touching the screen. Optical touch screens are highly accurate and can be used with gloves or styluses.

5. Projected capacitive touch screens: These screens use a grid of electrodes to detect changes in electrical current caused by touching the screen. Projected capacitive touch screens are highly durable and sensitive.

6. Haptic feedback: This feature provides tactile feedback in response to touch, such as a vibration or click sensation, to improve usability and reduce errors.

Overall, the specific type of touch screen feature used on a rugged military display will depend on the specific requirements and use case of the display.

7) I have a Form-Fit-Function type application challenge. Can you work within the existing dimensions and update my Cathode Ray Technology (CRT) to an LED display solution?

Form-Fit-Function CRT replacement is one of IEE’s strengths and competitive advantages. We specialize in backward and forward compatibility, and put more capability into the same footprint. See our case study here

8) 8) What type of optical bonding does IEE do?

Optical bonding is a process in which a layer of adhesive is used to bond the display module to the cover glass or touch screen, reducing the air gap between them and improving visibility in bright or outdoor environments. Rugged military cockpit displays often use optical bonding to enhance durability and reduce the risk of damage from shock, vibration, and extreme temperatures.

Full lamination: This process involves bonding the display module to the cover glass or touch screen using a layer of adhesive, with no air gap between them. Full lamination reduces reflections and improves visibility in bright or outdoor environments.

OCA (Optically Clear Adhesive) bonding: This process involves applying a layer of adhesive between the display module and the cover glass or touch screen, with a minimal air gap. OCA bonding provides good optical performance and durability, but may not be as effective in reducing reflections as full lamination.

EMI shielding: Some displays may incorporate a layer of conductive material between the display module and the cover glass or touch screen to provide electromagnetic interference (EMI) shielding. EMI shielding helps to protect sensitive electronics and ensure reliable operation in harsh environments.

Anti-reflective Coatings can be applied to the cover glass or touch screen to reduce glare and improve visibility in bright or outdoor environments. Anti-reflective coatings can be combined with optical bonding for improved optical performance.

Impact-resistant glass: Displays may incorporate specially designed cover glass or touch screens that are resistant to impact and scratches, reducing the risk of damage from shock and vibration.

9) What specific optical bonding processes do you do in-house?

All of it. IEE specializes in optical bonding to enhance our customer’s displays. We use DuPont ™ Vertak™ in our adhesive and bonding process. Our manufacturing floor has adhesive dispensing equipment and a UV curing oven; along with a hot roller and autoclave machines that provide laser cutting capability and applying laminated optical and EMI filters.

10) I have my own displays that need optical enhancements. Do you provide that service a-la-carte?

No, IEE does not provide added features and enhancements to other outside displays. We are available to begin the redesign, engineering and manufacturing of any replacement display you might need.

11) In addition to optical bonding, what other type of display enhancements does IEE do?

Optical bonding is one process that strengthens and ruggedizes a display. Additional techniques include using anti-glare, backlighting systems, transflective screens and touchscreens that minimize light loss. Learn more about IEE Optical Enhancements here.
