OLEDs / NHD-0216CW-AB3 dots underneath characters
« on: November 19, 2015, 10:26:39 AM »
I've got this screen set up using SPI at 3.3V an it seems to be working other than I get a single row of dim pixels underneath the characters. If I stop writing to the display the dots go away and just show the static characters. As the characters change I get a different arrangement of dim dots.

I am writing to the display every 40mS and showing a changing value.

I have tried slowing the clock down to 500Khz but no effect. My SPI timings seem to match the US2066 data sheet.

Any suggestions to fix this would be gratefully received.

Hi, is there a 3D model available for this OLED character display module?
