Abstract

An apparatus for preventing abnormal voltage, a light emitting module, and a display apparatus are provided. The present apparatus for preventing abnormal voltage extracts the highest voltage and the lowest voltage among voltage applied from a plurality of loads, includes two voltage distribution units distributing the highest voltage and the lowest voltage, and detects whether the highest voltage and the lowest voltage applied from the voltage distribution unit are within a predetermined range. Accordingly, the apparatus for preventing abnormal voltage is not affected greatly in terms of its size and cost even if the number of loads to be protected increases.
