As a data point, a NewHaven NHD-0420DZW-AG5 OLED works fine with the 7I73
(the G means Green, the other colors should be OK also)

It requires 3.3V VDD or 1 diode drop in VDD from 5V

Contrary to the data sheet suggestion, we did have to ground the LCD D0..D3 pins for consistent behavior

You also need to make sure the display is powered up when the 7I73 is powered up so the 7I73 display initialization is done.

thanks for the tests.
You tested with the Andy lcd.comp component?

I test my oled again with d0 to d3 at the ground
but unfortunately I still blinking the cursor
like my video.

If you have the same display, we can compare notes/hal files if there's still an issue
