Thanks for posting on the forum. Those are some fairly specific values for the dimensions of OLED, once you go down below 2.d.p in inches we’re talking about fractions of a millimeter (specifically 0.01" = 0.254mm exactly) the values beyond that start to become significantly smaller than any reasonable manufacturing tolerance could claim.
I’m quite sure that we don’t carry any 480x270 non-touch OLED displays ourselves, but I’ve linked our category for it below in case you’d like to take a look, if you have any other questions please let us know:
Core Electronics don’t stock the particular display you’re after unfortunately from what I could find. We’ve got a 3.2" Touchscreen LCD with 240x320 pixels, but no OLED 480×270 non-touch versions. I’d suggest taking a look at Mouser for it.
I don’t know whether they’ve got anything matching those exact specs, but this criterion search should help you:
