SPECIFICATION
This is the specification for the high performance
Backlight System that is used to illuminate a 5.0-inch
AMLCD display head.
The backlight is a closed loop luminance sensed system.
A sensor monitors the bulb's luminance output and
compares it with the control voltage to regulate output.
The luminance is maintained over time and temperature
variations.
Our multi-bulb system offers built-in redundancy for
continued lighting in the event of single bulb failure. A
built-in lamp heater assembly maintains bulb temperature
at its optimum level. External shutdown of the heater and
lamp power are controlled via an external input. When
lamp replacement is required, an output pin signals
low.
External voltage input is a differential input that provides
common mode rejection of common mode noise. The
luminance output versus input voltage response is non-
linear to provide easy adjustments at low luminance.
