The factory preadjusts the viewing angle of the display by setting the LCD bias voltage to 10.2 Volts using the
on–board potentiometer. This is considered to be a nominal adjustment, but the user may prefer to vary this to
optimize the viewing for a particular application. The bias voltage is measured between V
(pin #2).
The viewing angle and contrast ratio may be externally controlled using an additional 10K ohm potentiometer.
The potentiometer on the rear of the module must first be set to the maximum resistance by turning the
adjustment fully counterclockwise. A 10K ohm potentiometer can then be connected between pin numbers 4
and 22 on the connector. Since the module has wide viewing angle characteristics and built–in temperature
compensation of the viewing angle, the user may find that this external viewing control is unnecessary.
