Luminescence driving apparatus, display apparatus, and driving method thereof |
摘要 |
A luminescence driving apparatus, a display apparatus, and a driving method thereof are provided. The luminescence driving apparatus drives a plurality of light-emitting units and includes: a voltage sensor which senses internal voltages of the plurality of light-emitting units; a current sensor which senses internal currents of the plurality of light-emitting units; a sensing signal generator which receives the internal voltages of the plurality of light-emitting units from the voltage sensor to generate an overvoltage sensing signal; a controller which, if it is determined that an overvoltage state has occurred, according to a level of the overvoltage sensing signal, searches for at least one of the plurality of light-emitting units in which the overvoltage state has occurred, according to levels of the internal currents sensed by the current sensor; and a protector which performs an overvoltage protection (OVP) operation with respect to the searched light-emitting unit.
