Abstract
A touch control glazing includes a first transparent glazing; an electrically conductive layer and a capacitive touch sensitive device including a touch sensitive structure formed in the electrically conductive layer, the touch sensitive structure including a ground electrode and a touch electrode having a touch sensitive area; and a light emitting diode arranged on the electrically conductive layer to indicate the touch sensitive area, the light emitting diode having a light emitting surface facing at least partially the touch sensitive area, the light emitting diode having a first terminal being an first electrode zone electrically connected to the ground electrode and a second terminal being a second electrode zone electrically connected to the touch sensitive area.
