PIXEL AND ORGANIC LIGHT EMITTING DISPLAY DEVICE

摘要

A pixel and an organic light emitting display device are provided to display an image with desired brightness by compensating deterioration due to the organic light emitting diode through control of the voltage of gate electrode. In a pixel and an organic light emitting display device, a transistor (M2) supplies a current to an organic light-emitting DIODE (OLED). A pixel circuit(142) compensates for a threshold voltage of the transistor, and a storage capacitor (Cst) is included in a pixel circuit. A storage capacitor is connected between a gate electrode and i-1 the luminous control line of transistor, and a compensation(144) controls a voltage of the gate electrode of transistor to compensate the deterioration of the organic light-emitting DIODE.
