Allowing temperature control of optical, lens, and display assemblies, the Therma Klear Flex series of thin flexible transparent heaters from Dontech provide the warmth necessary to extend the operating temperature of LCDs in cold environments (0 to below -40°C) and for anti-fog, anti-icing, and de-icing of optics, sensors and display assemblies. Applications include avionics displays, vehicle displays, mobile computers, kiosks, and handheld devices. Custom sizes are available up to a 24” diagonal. The heaters can be supplied with an optical grade pressure sensitive adhesive for optical coupling purposes. They are constructed using the company’s VCF visually transparent conductive coatings applied to flexible optical grade polyester. Custom substrates are available. The conductive coatings are single or multiple-layer, thin film deposited coatings with a resistance from 5 to 200 ohms/sq. When an electrical current flows through the coating, the filter will generate heat. Typically 0.007” in thickness, the heaters require very little room and are easily integrated into most mechanical footprints. With dielectric enhancements, light transmission of heaters can exceed 90%, allowing for minimal degradation to the optical performance of the assembly. The company’s proprietary lead wire attachment method is highly durable for custom mechanical and electrical configurations, as well as EMI/RFI attenuation. Recommended power settings are from 0.1 to 1.0 watts per square inch.
