Dimming
Analog dimming is available on the EL160.120.39 display by connecting a
50K(ohm) logarithmic external potentiometer to the dimming port.
Alternatively an external voltage or current-mode D/A converter may be used
to dim the display by sinking a 0-250
µ
A current at 4-0 voltages respectively
from the control pin to ground. For information on controlling display
brightness by frame rate, please refer to Planar Application Note 120.
