Display Heater (eHeater): a transparent and high efficient ITO heater for display
ALP offers ITO heaterson plastic or glass sustrate. The heater is usually terminated on the opposite sides with silver or copper bus bars. A contacting wire is securely soldered on the bus bar and ready for power supply. The properties and heating efficiency of ALP's LCD heater bonded 10.4" touch screen was measured and given as an example.
The features of an eHeater
- 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.
