LCD heaters are constructed of a layer of electrically conductive transparent film with screen printed parallel bus bars positioned along the edges. Lead wires are then attached to the bus bars to provide means of electrical connection. These heaters can be provided with optical grade adhesive, laminated on the back, for easy mounting in front or behind an LCD display. Applying power to the bus bars, through the lead wires, creates a uniform heated surface. Maximum wattage of up to 1.0 W/in2 is recommended. (Wattage is a function of input voltage, surface resistively and heater geometry)
