A device for driving capacitive light emitting elements includes a plurality of electrical charge recovery switches that send a current corresponding with an electrical charge, which has accumulated in a capacitor, individually to a plurality of drive electrodes connected to the respective capacitive light emitting elements. The surface moves relative to the substrate and to conform to the substrate. A compensator receives an input signal and thus generates the optical pickup control signal. The method further includes acquiring resources needed for the process with the impersonation token.
