摘要： In a pixel circuit of an organic EL display device, a gate of a driving transistor is coupled to a gate of a compensating transistor, which is configured to operate as a diode. A precharge voltage is applied to the gate of the driving transistor while a selection signal is applied to a previous scan line, so that the compensating transistor is biased in a forward direction to apply a data voltage on the gate of the drive transistor. The driving transistor may be electrically isolated from the organic EL element (OLED) while precharging, so as to prevent the OLED from emitting a light using the precharge voltage. In addition, the driving transistor may be electrically isolated from the OLED while the data voltage is being charged, so as to prevent the OLED from emitting a light.

摘要： An organic light emitting display device includes a scan driver, a data driver, and pixels. The scan driver is for sequentially supplying, during each horizontal period of a width 1H, a scan signal with a width of at least 2H to scan lines. The scan driver is further for sequentially supplying an emission control signal to emission control lines that are substantially parallel to the scan lines. The data driver supplies data signals to data lines. Each pixel includes an organic light emitting diode (OLED), a pixel circuit having a first transistor for controlling the amount of current supplied to the OLED, and a compensator for controlling the voltage of a gate electrode of the first transistor for compensating a degradation of the OLED. The compensator includes two transistors and a capacitor. One transistor is coupled to a scan line, and the other is coupled to an emission control line.

摘要： An organic electro-luminescent display apparatus can compensate for the threshold voltage and voltage drop of the driving transistor. The organic electro-luminescent display apparatus divides and drives an initialization time, thereby improving a contrast ratio. The organic electro-luminescent display apparatus minimizes or reduces the change of a current due to a leakage current by correcting the leakage current corresponding to a data voltage with a fixed power source, thereby improving crosstalk. The organic electro-luminescent display apparatus adjusts the duty of the emission control signal, thereby removing or reducing motion blur.
