LCD heaters
are constructed of a layer of electrically conductive transparent
film with screen printed parallel busbars positioned along the edges.
Lead wires are then attached to the busbars to provide means of
electrical connection. These heaters can be provided with optical
grade adhesive, laminated on the back, for easy mounting in front
or behind an LCD display.Applying power to the busbars, through
the lead wires, creates a uniform heated surface. Maximum wattage
of up to 1.0 W/in2 is recommended. (Wattage is a function of input
voltage, surface resistivity and heater geometry)
The
typical operating temperature for TN LCDs
is -30 to 80C. For STN LCDs the operating temperature is -20 to
80C. With the help of an LCD heater, the LCD operating temperature
can be extended to -55 to 90C. The addition of an LCD heater will
greatly improve the LCDs performance at lowrt temperatures.
Typical Applications: Avonics displays, Ruggedized
electronic devices, Portable military radios, Handheld terminals,
Outdoor card readers, Defogging windows in environmental chambers,
Gas pump, parking meters, Heating microscope stages.
