Does anyone know what kind of technology is used in the small fold-down
screens in some of the newer airplanes? The image quality is good enough
that it seems like active-matrix screens, but I'm surprised that the
airplane companies can put so many screens in the plane without
significantly increasing the cost of the plane.
