LIGHT EMITTING DISPLAY DEVICE AND DRIVING METHOD THEREOF

摘要

PURPOSE: A light emitting display device and a driving method thereof are provided to improve image quality by compensating threshold voltage of a driving transistor. CONSTITUTION: A gate terminal of a first switching device(SW1) is connected to a second light emitting control line. A gate terminal of a second switching device(SW2) is connected to a first scan line. A capacitor(C) is connected between a second node and a third node. A gate terminal of a third switching device(SW3) is connected to the first scan line. A light emitting device(OLED) comprises a light emitting cell. A gate terminal of a driving transistor(DT) is connected to the second node. A gate terminal of a fourth switching device(SW4) is connected to a second scan line. A gate terminal of a fifth switching device(SW5) is connected to a first light emitting control line.
