Abstract
The invention relates to supervision circuits (10) for supervising organic light emitting diode devices (1) via detection circuits (20) for detecting failure states of the organic light emitting diode devices (1) and for generating decision signals in response to detected failure states of the organic light emitting diode devices (1), which detected failure states have durations equal to or larger than time intervals. In response to the decision signals, the organic light emitting diode devices (1) can be bypassed and deactivated through switching circuits (30) such as bi-stable circuits. The failure states may include that the organic light emitting diode devices (1) have a relatively low impedance or “short” and a relatively high impedance or “open”. The supervision circuit (10) further prevents the organic light emitting diode devices (1) from being bypassed unjustly. The supervision circuits (10) may be autonomous circuits that only receive power via the organic light emitting diode devices (1) and may be automatic circuits that automatically reset themselves after turn-off.
