Good day 

I have the following screen

NHD-0440AZ-FL-YBW

Im repairing a device with similar screen, but i do not have any contrast adjustment on the device, and i dont have access to the code.

Is there a way to adjust or set the contrast in any other way?

Thanks in advance

  Hello,

  The contrast for that display is controlled via Pin 12 (V0 ~0.5V) and Pin 13 (VSS ground). Now you mentioned that you want to control the contrast on a similar display, keep in mind that the other display may have a different method to control contrast or use different pins.
