Dontech designed and produced optical display components to upgrade the LCD to achieve high-level performance for a process monitor display used in a surface mining application. The display assembly was comprised of an abrasion, chemical, and impact resistant polycarbonate filter with an antireflective coating applied to the front surface. The rear surface of the filter contained a 30 ohm/sq transparent conductive coating that was integrated by Dontech into a transparent heater to extend the operational thermal range of the LCD. The heater contained flexible polymer silver-filled busbars with wire lead attachments. The filter assembly was optically bonded to the front of the LCD for ruggedization and improved sunlight readability. Dontech test and characterization capabilities supported qualification of the system including ball drop testing, chemical resistance testing (cleaning and wash-down fluids), thermal cycle and shock, and humidity exposure.
Since 1971, we have been creating components to improve the performance of optical systems, supporting our customers from concept to final system delivery. Dontech engineers, manufactures and integrates custom parts for optical, electronic display, touchscreen, and optical and electronic assembly markets. We also produce functional coatings for components used on satellites and interplanetary spacecraft. We manufacture optical filters, laminations, thin and thick film coatings, precision conductive optical grids, electronic traces, and other enhancements to service the military, avionics, aerospace, medical, industrial and government markets.
We are proud of the partnerships we build with our customers, and we are ready to use our expertise to support your program. Dontech’s Quality Management System is AS9100D and ISO-9001:2015 certified with TUV Rheinland of North America.
