Ultra-thin flexible clear heaters deliver heat while transmitting over 80% of visible light.
Featuring a micro-thin wire-heating element in between optical-grade polyester sheets, these heaters provide reliable uniform or profiled heat patterns without blocking light. They are ideal for heating LCDs, cockpit professional displays, outdoor professional card readers, portable military radios and professional computers and for optical deicing and defogging. They are perfect when you need heat with light shine-through.
Most dot matrix LCDs lose sharpness and response speed below 0°C. But with these Thermal-Clear™ heaters, you will achieve performance at temperatures as low as -55°C. The heater is sandwiched between the backlight and the LCD in a typical installation. An optional light diffuser will soften and conceal any shadows cast by the heater element. Special element routing and profiling also optimizes the LCD’s clarity.
Thermal-Clear™ heaters are low mass and have high watt densities for fast warm up. Tight resistance tolerance provides constant and repeatable wattage output for longer battery life. Heaters can be rectangular, round or irregular shapes with uniform or profile heating patterns. Fine wire elements deliver long life with high performance. The rugged polyester construction prevents damage during installation and operation. Available in sizes to 280mm by 560mm, they are RoHS compliant.
Options include integrated RTDs or thermistors for accurate temperature sensing, Heaterstat™ sensorless controller and flex circuit terminations.
