Yedaya, in case you didn't catch it, LDO is an acronym: https://en.wikipedia.org/wiki/Low-dropout_regulator The vendor driver probably calls it that, because the input leg of the panel's driver IC just so happens to be connected to a regulator of this kind If we don't know the actual name of that input and have no way to verify it, I think 'power-supply' would be a good generic consensus, it happens to be reasonably common across other bindings Konrad
