I'm using a OLED character display (NHD-0420CW-AB3) for a R n D project. but I have a problem of burn in images were displayed on some parts of the display screen. I have changed the contrast to the lowest value using the command but the problem occured. Also the lowest contrast also too high. we are going to buy some bulk quintity. but the issue is the burn in images occured for a few month of time interval since first use. How can we control the life time of pixels evenly and is there any solution or recommendations to solve that.also we need more control o the brightness of the display. Thank you.

The contrast control for this display is the main way to reduce the brightness.
The best way to reduce the image burn effects on a passive matrix OLED display is to provide even wear across all of the pixels. Any static image will,in time produce image burn effects as each of the organic pixels wear individually. Blanking the display or scrolling characters will help reduce the effects of uneven wear of the pixels.

Best Regards,
