LUMINESCENCE DRIVING APPARATUS, DISPLAY APPARATUS AND DRIVING METHOD THEREOF

摘要

PURPOSE: A light emitting driving apparatus, a display apparatus, and a driving method thereof are provided to reduce the number of IC(Integrated Circuit) pins by simplifying an output voltage OVP(Over Voltage Protection) circuit of a driving IC. CONSTITUTION: A voltage sensing part(220) senses internal voltage of each light emitting part among a plurality of light emitting parts. A current sensing part(210) senses internal current of each light emitting part. A sensing signal generator(230) receives the internal voltage of each light emitting part. The sensing signal generator generates a single sensing signal. A controller(240) searches one or more light emitting parts in which an overvoltage state is generated. A protection part(250) performs an overvoltage protection process with respect to the searched light emitting part.
