Abstract
The present invention relates to an MID device (51) comprising an OLED (52) and a short detection circuit (53) for detection a short in the OLED (52). The short detection circuit (53) comprise a temperature sensing unit (55) tar sensing a first and a second temperature of the OLED (52) and a short detection unit (56) kw detecting the short based on a difference between the first and the second temperature. Therewith, the short detection can be less sensitive with respect to production tolerances resp. OLED binning.
