A method for identifying connected devices and an electronic device using the method are disclosed. The source connecting layer is electrically connected to either the gate connecting layer or the transparent connecting layer via the at least one conductor region. In one embodiment, a digital delay circuit is used in conjunction with a processing circuit to continuously measure the jitter of an input clock signal, thus providing clock signal performance measurement over time. It was recognized that with such a low photon flux especially fine structures can advantageously be transmitted into the recording medium without the irradiation having to be partially blocked by a mask. An input device from a group of input devices is associated with the controller, wherein the input device generates an input signal to operate the appliance.
