Demanding military environments require high-level and mission-critical performance from tactical vision systems, vehicle maintenance, and other support devices. Dontech’s filters and display assemblies can address the functional requirements of the application including impact resistance, sunlight readability/contrast enhancement, EMI/RFI shielding, low and high temperature mitigation, night vision imaging system (NVIS) compatibility, and environmental and mechanical ruggedization. Dontech utilizes various substrate materials to meet the performance, weight, and cost requirements of an application.

 

Whether constructed from a chemically strengthened glass or plastic material (e.g., PMMA, polycarbonate), Dontech’s products are designed to exceed impact requirements including boot, wrench, and ball-drop tests. Sunlight readability and contrast enhancements are achieved through active and passive enhancement of the backlighting and film layers of LCDs, antireflective and antiglare surface coatings, optical bonding technologies, and polarization optimization to conserve power consumption and reduce internal reflections typically resulting from the touchscreen and LCD film interfaces.

 

EMI/RFI Shielding

Electronic communications produce radio frequency emissions that can disclose sensitive information and intelligence if intercepted. The EMI/RFI shielding technologies incorporated into Dontech filters provide countermeasures to ensure information security. Our optics shield for both radiated susceptibility and radiated emission compliance. Dontech manufactures optical shielding solutions with fine conductive optical grids, which includes both patterned (e.g., etched) metal films and conductively electroplated woven fine wire meshes. Standard Dontech woven mesh is available from 50 through 255 openings per inch (OPI) and from 80 to 160 OPI for patterned/etched mesh. For improved optical performance and lower shielding requirements, transparent conductive (e.g., ITO) coatings with resistances as low as <1 ohm/square are available.

 

Thermal Management, NIR Control, and Ruggedization

Transparent heaters and solar reflecting components can extend the operational temperature range of display assemblies and sensing optics. Dontech produces NVIS filtering technology that is integrated into the display assembly and tailored to the application needs (i.e., NVIS friendly to fully compliant to MIL-STD-3009). Additionally, Dontech can incorporate features such as mounting frames, bezels, and gaskets for environmental, water immersion, and shock and vibration ruggedization. Dontech’s optics integration solutions are highly customizable, providing the broadest range of highly customizable optical and shielding solutions available.

 

Display and Touchscreen Solutions

Dontech’s display assemblies and filters for military applications are used to enhance the performance of electronic displays (e.g., LCDs and OLEDs) and touchscreens (e.g., 5 wire resistive and projected capacitive) so that the display assembly can meet the demanding ruggedization, optical, and environmental requirements of military applications.

 

Dontech’s extensive in-house, clean room manufacturing and metrology/testing capabilities enable us to control the performance driving variables of our display enhancement products tightly and uniquely. Highly specialized control over key processes ensures the reliability of critical systems such as military displays, which have very expensive qualification and requalification protocols. Dontech’s broad in-house processing allows us to support legacy products such as CRTs and analog displays for well over 20 years to extend the program’s or product’s useful lifetime.
