I have looked up IPS. It is just a variation of TFT LCD. The full name would be “In-plane switching Thin film transistor liquid crystal display” (IPS-TFT-LCD).

Like all LCD it is optically passive (it does not emit photons by itself) and need additional light (usually build in). And it is a pretty old technology (1996).

Interestingly enough AMOLED too is a TFT technology. It would be “Thin film transistor organic light-emitting diode” (TFT-OLED) but I guess the manufactures decided against that as it would lead to confusion with the consumer and went for “Active matrix organic light-emitting diode” instead. But AM is only a more general term for TFT (TFT ∈ AM).

So long talk short meaning: The real difference is LCD vs LED no matter how many extra letters you put in front of the name.
