Thermal-Clear Thin, Flexible Heaters for Displays

July 2, 2008
Minco's thin, flexible heaters achieve performance at temperatures as low as -67°F.

A line of flexible heaters designed to provide accurate, reliable, and rapid heat in a lightweight, thin profile, Thermal-Clear heaters feature a micro-thin wire-heating element sandwiched in between optical-grade polyester sheets. With reliable uniform or profiled heat patterns without blocking light, they're ideal for heating LCDs, cockpit displays, outdoor card readers, portable military radios & computers, and for optical deicing & defogging. 


Etched foil or wire-wound heater elements can have uniform or profiled heat patterns. These heaters can integrate temperature sensors, flex circuits, controllers or other electronics to provide a total heating solution. Choose from a selection of standard configurations or choose a custom heating solution.


Most dot matrix LCDs lose sharpness and response speed below 32°F (0°C). With Thermal-Clear heaters, you can achieve performance at temperatures as low as -67°F (-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 optimize the LCD’s clarity.


Available in sizes of 11 x 22 in. (280 x 560 mm), they are RoHS compliant. Options include integrated RTDs or thermistors for accurate temperature sensing, Heaterstat sensorless controller, and flex circuit terminations.
