ORGANIC LIGHT EMITTING DISPLAY AND METHOD FOR DRIVING THE SAME

摘要

An OLED(Organic Light Emitting Display) device and a driving method thereof are provided to extend the lifetime thereof by adjusting the magnitude of voltages, which are supplied to a display unit. An OLED(Organic Light Emitting Display) device includes a display unit(210) and a power supply unit(250). The display unit includes signal lines having scan, data, and power lines, and plural pixel circuits, which are positioned at regions which are defined by the signal lines. The power supply unit supplies driving voltages having different magnitudes from one another to the display unit according to the luminance of images displayed in the display unit through the power lines.
