Overview
Featuring a micro-thin wire heating element laid in a pattern 
between optical grade polyester sheets, Thermal-Clear™ heaters 
provide reliable heat without blocking light.
 • Custom heater element routing and profiling optimizes the 
visual clarity of the LCD and prevents “shadowing”
 • Tight resistance tolerance provides constant and 
repeatable wattage output for longer battery life
 • Low mass and high watt density offers faster warm up 
time needed for immediate LCD response in cold weather 
operation
 • Rugged materials prevent costly damage during 
installation and handling
 • Integral temperature sensors optional
 • Rectangular, round, or irregular shapes
 • Uniform or profiled heat patterns 
Applications
 • Cockpit displays
 • Ruggedized computers
 • Portable military radios
 • Handheld terminals
 • Outdoor card readers
 • Portable and vehicular computers
 • Camera lens deicing
 • Defogging windows in environmental chambers
 • Heating microscope stages
Custom options
 • Integral RTD or thermistor sensors
 • Flex circuit terminations
 • Rigid materials
 • Custom shapes and sizes to 11” × 22” (280 x 560 mm) 
 • RoHS compliance
 • Contact Customer Service for design assistance
Thermal-Clear heaters and LCDs
Most dot matrix LCDs lose sharpness and response speed 
below 0°C. Achieve acceptable performance at much colder 
temperatures with a Minco Thermal-Clear heater. 1-2 Ω/in² 
(0.16 - 0.31 Ω/cm²) will keep a typical LCD operating properly in 
ambients as low as -55°C.
