Organic light emitting display device and driving method thereof |
摘要 |
The present invention has been made in an effort to provide an organic light emitting display device comprising a panel; a power supply supplying power to the panel; a current detection unit detecting a current flowing through power line wiring of the panel and outputting the detected current; and a power controller comparing the detected current with a current value configured internally and outputting a shutdown signal which turns off the power supply if the detected current exceeds the predetermined current value. |

1. An organic light emitting display device, comprising:
a panel including power line wiring wired up for individual blocks; a driving unit driving the panel; a timing controller controlling the driving unit; a power supply supplying power to the panel; a current detection unit detecting a current flowing through the power line wiring of each block and outputting the detected current of the block; and a power controller comparing detected currents of the individual blocks with each other and outputting a shutdown signal which turns off the power supply if a current higher or lower than the currents of the other blocks is detected. |
