ANTI-REFLECTIVE AND ANTI-GLARE SOLUTIONS
To optimize image quality in all situations, we can complete an analysis of your specifications and project environment and, if needed, provide AR/AG solutions. Don’t miss out on the new products based on latest technological advances in this field. Examples of options include:
● Multilayer HEA® (High Efficiency Antireflection) AR-coated glass - Its brasion resistance rating: the coating shall be subjected to a 20 rub eraser abrasion resistance test and meet the requirements referenced in paragraph 4.5.10 of MIL-C-675C for sleeking at the area of abrasion.
● EagleEtch glass from Europtec - Mostly using the 95 gloss, because compared to coated types, it offers more durability in harsh environments.
● HD PrintFree coating by MAC - This is a very popular oleophobic AR coating on CT glass and also on-top of the AG glass to achieve “the Rolls Royce spec” of AR/AG/AF/CT.
OPTICAL BONDING
Optical bonding can increase the brightness and contrast of a display. Typically, there are air gaps between the layers of the completed LCD assembly including the substrate, cover glass and touch screen. Optical bonding can be employed to strengthen the assembly and in most cases, to improve the overall brightness, contrast ratio and readability by mitigating the light reflection between the layers. We offer variety of bonding solutions to meet your LCD touch screen monitor requirements. Don’t miss out on the new products based on latest technological advances in this field. Examples of options include:
1. Dry Bonding with OCA - When you need to increase readability (especially in direct sunlight) by eliminating air gap between LCD and touch screen or protective lens, or both, Impact effectively achieves that goal with optical clear adhesive (OCA) lamination process. Dry bonding with OCA is an inexpensive bonding method with a reliable track record.
2. Wet Optical Bonding with IR Curing (55” and up diagonal) - Performed in the U.S., Impact uses IR-curing process for optical bonding that involves infrared heat to bring optical silicone OCR material to gel state. Used to optically-bond touch screens of your choice or variety of lenses similar to options for UV curing listed above but excluding Micromesh option.
3. Wet Optical Bonding with UV Curing (up to 27” diagonal) - Performed in the U.S., Impact uses UV-curing process for optical bonding that involves no heat with a unique patented non-optical silicone OCR bonding material (urethane acrylate) to be brought into a gel state in a Class 100 environment. Wet bonding ensures superior quality over infrared/IR curing technique and solves any delamination concerns for customers compared to dry-bonding. The following options are available:
Bonding to a touch screen of your choice to an LCD

EMI MITIGATION
Many environments, such as aircraft and the medical industry are susceptible to the effects of electro-magnetic interference. We engineer a variety of solutions for EMI mitigation, to help reduce this type of interference. Don’t miss out on the new products based on latest technological advances in this field. Examples of options include:
● ITO-Glass or Mesh-Glass based EMI shielding - see section above about Optical Bonding for list of EMI shielding options
● EMI shielding along the perimeter of touch screens
INCREASED OPERATIONAL TEMPERATURE RANGE FOR LCDs
● While many standard displays are rated for -30C already, both display panels and monitors can be operational all the way at -40C with optional heaters. Heaters may be controlled via manual adjustment or automatically when paired with thermistors.
● On the high spectrum, Impact uses LCD panels and monitors of High TNI of +90C or +105C. TNI is "twisted nematic isotropic" transition temperature. A high TNI panel is designed to prevent blackening when the display operates under elevated temperature conditions such as outdoors. Basically TNI is when the LCD turns black and is unreadable.
COMPUTER SYSTEMS
● Impact's San Diego-built computer systems are offered With or without O/S (operating system), with Long life cycles without changes to the design, and with Optional WiFi / Bluetooth / Cell Modem.
● High reliability with MTBF / Mean Time Between Failure for computer motherboards on average 50 years at 45C @24/7 use, with some motherboard models reaching 173 years (MTBF documents available upon request).
● Security features of computer systems: Latest TPM, Hardware Watchdog, Anti-Intrusion, Computer systems based on German-made motherboards (= U.S. friendly) are available.
● Extreme temperature options for computer motherboards/SBCs and complete computer systems such as workstations and servers (as seen here), computer models operational -40C to +70C are available.
RUGGED TABLETS (LCD + SBC)
● Bulk vs. Performance: Rugged tablets need thick casings and protective elements, which can make them bulky and heavy. This can be cumbersome for users and limit portability. Finding the right balance between toughness and a slim design is a constant struggle. Impact has experience combining slim-profile touch displays with thin fanless SBCs.
● Port Protection vs. Accessibility: Rugged tablets need protection for ports like USB and HDMI, but this can make them difficult to access and use. Designing covers or flaps that offer protection while allowing easy use adds complexity. Impact has means of eliminating cumbersome cables and combining slim-profile touch displays with thin fanless SBCs via special space-economical interfaces seen here (Impact's industrial & gaming kit consists of 15.6” LCD assembled with PCAP touch screen interfaced to D3714 SBC with AMD Ryzen CPU via just two cables: eDP & USB) - video
● Screen Protection vs. Clarity: Rugged tablets often have touchscreens with added shatter protection. However, these protective layers can reduce touch sensitivity and screen clarity. Finding the right material balance to achieve both durability and a good user experience is crucial. To mitigate those concerns, Impact provides Optical Bonding services.
● Complying with Multiple Standards: Rugged tablets need to meet various industry standards for dustproofing, waterproofing, shock resistance, and extreme temperatures. Juggling these different requirements can be complex during the design phase.
● Rigorous Testing Procedures: Testing rugged tablets thoroughly is essential, but these tests can be expensive and time-consuming. Finding the right balance between efficient testing and ensuring durability is a challenge. To address both points above, Impact provides sunlight readability, shock resistance, extreme temperature options for displays (more info) and for computer motherboards/SBCs (as seen here)
● Battery Life vs. Ruggedness: Adding protective features can limit space for batteries, reducing battery life. This is a concern for users who need their tablets to last long shifts without needing a recharge. Impact’s displays and motherboards/SBCs are low power and can be fanless.
● Heat Dissipation: Rugged tablets often have powerful processors for demanding tasks. Designing a system that efficiently dissipates heat while maintaining a sealed and protected form factor is a challenge. Impact is offering displays and motherboards/SBCs that are low power and fanless addresses those concerns.
