Display Heater (eHeater): an transparent and high efficient ITO heater for display

To maintain display operating in regions with very cold weather would require a display heater to defrost the window or to warm up the LCD to prevent the liquid crystal been "frozen" up. Applications that may need to have a display heater include ground/avionic/naval military control systems or agricultural and oil-detecting equipments. RSP offers ITO heaters. The heater is usually terminated on the opposite sides with copper bus bars. A contacting wire is securely soldered on the bus bar and ready for power supply. The properties and heating efficiency of RSP's LCD heater bonded 10.4" touch screen was measured and given as an example.

  • Resistance 5 ~ 20 ohms/sq
  • High transmittance, ~ 87%
  • Thickness 0.7 mm or 1.1 mm
  • Sunlight readable
  • High thermal stability
  • Extra durable bus bar soldering
  • Optional durability enhancement
  • May be integrated with EMI/Touch screen

The LCD heater may be non-bonded or bonded to the other functional part, such as a protection cover, an EMI shield, and/or a touch screen. Our studies indicated that the heating efficiency of our LCD heater is equivalent in non-bonding and bonding configurations.
