Fullchance’s CrystalHeat® transparent heaters are constructed of a layer of electrically conductive transparent film with screen-printed parallel busbarspositioned along the edges. Lead wires are then attached to the busbars to provide means of electrical connection. Applying power to the busbars, through the lead wires, creates a uniform heating surface. Maximum wattage of up to 1.0 watt/in2 is recommended for most applications. (Wattage is a function of input voltage, surface resistivity and heater geometry.) These heaters can be provided with optical grade adhesive, laminated on the back, for easy mounting in front or behind an LCD display. Fullchance’s CrystalHeat® transparent heaters are designed for use with LCD displays in military and commercial applications under harsh environmental conditions. CrystalHeat® prevents freezing of LCDs in cold environments hence making them readable in temperatures well below freezing point.

Transparent heaters are visually transparent substrates with electrically conductive coatings. When current flows across the coating, it generates heat. Fullchance Fullchance Klear™ transparent heaters provide the warmth necessary to extend the operating temperature of LCDs (liquid crystal displays) in cold environments (e.g., from 0° to below -40°C) and for the anti-fog, anti-icing, and de-icing of optics and optical displays. Fullchance manufactures heaters using different types of glass, acrylic, and polycarbonate substrates. Fullchance Klear Flex™ transparent heaters allow this same technology to be applied to flexible displays and optics. The transparent conductive coating in an optical heater is primarily comprised of different conductivities of indium tin oxide (ITO). The ITO can be dielectrically enhanced (index matched) to improve reflection and transmission properties in the desired optical performance band (e.g., visible spectrum, near IR). By index matching, reflection losses are converted to transmitted light. Fullchance can index match the conductive coatings to air (n=1), to the optical substrate, and to an optical adhesive (n=1.43 through n>2.36). Standard conductivities for ITO coatings range from <1 ohm/sq to >250 ohms/sq. Applications include avionic displays, vehicle displays, mobile computers, kiosks, and handheld devices.
