Hi

Your problem description is confusing.

  1. You mention SH1106, but the schematic shows SSD1306. Not a big difference, but for the charge pump it matters
  2. You mention backlight, but there is no backlight for OLEDs
  3. You write "off by 75-50%". What does this mean? The picture looks more like a software problem. Please post the code here.
