I work for a major LCD supplier (industrial, not consumer) and one of our top markets is the IFE market.
Right now we just completed an LCD design for a company that is installing 15.4" TFT LCD in to Lufthansa's Business Class on Boeing 747's & A330's.
We also are involved in IFE systems for the business jets also - we're providing LCD's to Leer, Embraer, Cessna etc.
