Capacitive touch screens have become widely adopted in mobile applications. Capacitive touch-screen display modules have conventionally been assembled by bonding two separate modules: 1) a touch-screen module with touch panel glass or film attached to the cover window, and 2) a display module, with a small air gap between them. An important role of the air gap is to decrease capacitive coupling of display noise to the sensors, and it is very effective since permittivity of air is more than 4χ lower than that of glass.
