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.
Dontech’s Quality Management System is AS9100D and ISO-9001:2015 certified with TUV Rheinland of North America. We are a designer and manufacturer of optical filters, laminations, and thin film coatings for the precision optics, display, and touchscreen markets.
Since 1971, we have designed and manufactured custom components that enhance the performance of optical systems from concept to final system delivery.
