ORGANIC LIGHT EMITTING DISPLAY AND DRIVING METHOD THEREOF

摘要

An organic light emitting display and a driving method thereof are provided to reduce the power consumption by adjusting the driving voltage. An organic light emitting display device comprises a pixel unit(100), a data driver(200), a scan driver(300), a power supply unit(500) and a driving voltage output unit(600). The pixel unit has a pixel. The pixel generates the light using the current flowing between the first and second power sources. The pixel generates the driving current corresponding to the data signal and the scanning signal. The data driver transforms the image signal into the data signal, and delivers to the pixel. The scan driver delivers the scanning signal to the pixel. The power supply unit outputs the first and second power sources through the first and second output terminals. The driving voltage output unit produces the voltage of the second power source corresponding to the magnitude of driving voltage. The driving voltage output unit prints out the voltage calculated through the second output terminal.
