A disadvantage of capacitive Touch Screen lies inside in its advantage. Where human touch makes work easy and quick on small and standard sized appliances there it becomes problem on a wide screen or if it is placed at higher place. Like it is not suitable for projectors because you cannot use hand everywhere and it becomes difficult to explain a higher point on the projector where your hand is not able to reach.

One more disadvantage of capactitive touch screen not in a particular sense though, it is expensive. On one side the resulting image is not perfect while on the other side offer high pricing which hinders it making a niche market. They offer less durability hence short life is another drawback.
