Hello to all,
I have a 20 x 2 character display that has an extended temp range -20
to + 70 (celsius). I don't want to use a potentiometer to adjust the
contrast ie) I would like to connect the Vo pin to ground through a
resistor, or to a voltage divider. I am worried that although this
may work well at room temperature, when the temp goes up or down, the
contrast will diminish and the display will be difficult to see. Does
anyone have any experience with this, will the display still be
visible at about -10 or + 35 degrees celcius. Any suggestions as to
how I should wire this pin. My display is from AZ Displays (ACM2002R).
Any suggestions would be appreciated.
Cheers,
Lucas
