When using a Liquid Crystal Display , it is very important to identify the range of its environmental temperature . The operating temperature of a standard display is above -10C and many displays need even warmer conditions. To ensure the function of the display in cold surroundings, it needs external heating .

Typical and critical applications are all types of outdoor mobile systems powered by batteries. In these applications the ZPZ foil will optimize the power consumption and save energy compared to traditional heaters .

Conflux ZPZ foil is a thin, self-regulating, PTC heating element based on the intelligent SIP compound and ZPZ design. It is a three-layered structure consisting of two sheets of copper separated by a conductive polymeric compound ( SIP ). The combination of SIP compound and ZPZ design saves power for when and where you need it.

The main advantages compared to traditional heating elements are:

• High power for optimal performance at low temperatures
• Low power and moderate heating for energy saving in warmer environments
• Pointwise temperature limiting
• No regulatory circuitry needed
  

• Voltage: up to 12V AC/DC
• Connection: prepared for soldering
• Power tolerance: ±15%
• Encapsulation: PET/PE
• Adhesive: 3M 200LSE
• Bulk thickness: 0.28mm (excluding adhesive)
• Maximum applied pressure: 2 kg/cm ²
• Overall heat transfer coefficient: 11 W/m ² K
• Operational, ambient temperature: -40to +100C
• Storage temperature: -60 to +60C
• RoHS compliant
• Designed for flat surfaces. Do not bend or fold.
  

• High initial heating power gives a rapid warm-up
  

• Smoother temperature distribution
• Low power density
  

• The surface temperature and power density are independent of area
• High design flexibility
