General Digital offers the Impact as a technology facilitator.
In its native form, it is intentionally designed as the most basic turnkey monitor General Digital produces. The Impact is comprised of the bare necessities and does not include features such as a protective enclosure, thermal management, etc.
It is intended to offer you, our OEM customers, with a low cost, turnkey product that can be easily integrated into your existing products, consoles, protective enclosures or kiosks. You may be required to contribute engineering content to your final installation to address issues of EMI, heat or safety.
Additionally, many Impact models are uniquely designed with the intent to be in compliance with FCC Class A and UL Certification, as well as to satisfy the needs of System Integrators/VARs and OEMs/End Users alike.
Protective and Versatile Electronics Frame
The Impact’s lightweight but sturdy metal mounting frame/enclosure has been optimized to reduce cost, protect the monitor’s electronics and facilitate a variety of mounting schemes. This inherent flexibility permits Integrators and VARs to quickly and easily design and manufacture their end-products around our fully functional display module.
General Digital offers a variety of optional bezels and enclosures to transform the modular Impact models into standalone, panel mount or rack mount devices.
Power
By default, the Impact is configured to operate from +12 Vdc. Optional AC switching power supplies are available.
For applications requiring a unique power source, we optionally offer DC input and/or DC-DC converters with a wider input power range and reverse polarity.
Video Support
General Digital offers a wide range of video controllers, allowing you to fine tune the display features to support your specific video requirements.
We can reprogram the video controller firmware/BIOS to support a variety of video timings and specialty needs, such as STANAG 3350 A, B and C, RS-343 and RS-170. Most of our video controllers will also support interlaced and non-interlaced analog video (Separate, Composite and Sync-On-Green) as well as live video signals such as NTSC, PAL or SECAM. Some controllers will also support HD-SDI or SD-SDI as a standard or optional feature.
Please consult a Sales Engineer to optimize your video controller selection.
Display Brightness and Night Vision Enhancements
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.
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.
Transmissive 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.
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.
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 sensitive, EMI filters, heaters, etc.
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 readable, NVIS 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.
