Abstract
An OLED device comprised of: an OLED means, a capacitive proximity sensing means for sensing a change in a capacitance, a mechanical element, and a means to provide a signal, wherein the OLED means and the mechanical element are movable relative to each other upon operation by a user and can assume a first position or a second position, wherein the capacitance is adapted to change between a first capacitance and a second capacitance when the OLED means and mechanical element are moved between the first position and the second position by an operator, and wherein the signal depends upon the capacitance.
