PIXEL AND ORGANIC LIGHT EMITTING DISPLAY DEVICE USING THE SAME

摘要

PURPOSE: A pixel and an organic light emitting display device using the same are provided to improve black luminance by including a boosting capacitor. CONSTITUTION: An organic light-emitting diode(OLED) is connected to a first power source and a second power source. A first transistor(T1) is connected between the first power source and the organic light-emitting diode. The gate electrode is connected to the first node. A third transistor(T3') is connected between the second electrode of the first transistor connected to the organic light-emitting diode and the first node. The gate electrode of a fourth transistor is connected to a luminous control line. A fifth transistor is connected between the fourth transistor, the connection node of the organic light-emitting diode, and second power source or a third power source. The gate electrode of the fifth transistor and the third transistor is commonly connected to a control line(CSn).
