Light emitting anomaly detection circuit

The utility model relates to a light emitting anomaly detection circuit. The light emitting anomaly detection circuit is used for rapidly detecting a light emitting device with a large number of light emitting elements. The anomaly detection circuit includes a power source module, a buffering module and an anomaly detection module; the power source module is used for outputting a first power source signal; the buffering module includes a plurality of buffers; a buffering input end of the buffers receives the first power source signal; a buffering output end of the buffers outputs a second power source signal to one of the light emitting elements corresponding to the first power source signal; the anomaly detection module includes a plurality of comparators; two detection input ends of the comparators are respectively and correspondingly coupled to the buffering input end and the buffering output end of one of the buffers so as to receive the first power source signal and the second power source signal; a detection output end of the comparators outputs a comparison signal; the anomaly detection module outputs a detection result according to the comparison signals of the comparator.
