A pixel capable of displaying images with substantially uniform luminance and an organic light emitting display device using the same are provided. An organic light emitting display device is driven in a frame divided into a reset period, a compensation period and an emission period. The organic light emitting display device includes pixels coupled to scan lines and data lines. First and second control lines are commonly coupled to the pixels. A control line driver supplies first and second control signals to the respective first and second control lines. A scan driver concurrently supplies a scan signal to the scan lines during a time in the reset and compensation periods. A data driver supplies a reset voltage to the data lines during the time in the reset and compensation periods.

An organic light emitting display device compensates for a variation of the threshold voltage of a driving transistor. A scan driver and a data driver drive a plurality of pixels. A pixel of the pixels includes an organic light emitting diode, four transistors, and two capacitors. A first transistor controls a current to the organic light emitting diode. Second and third transistors are coupled between a data line from the data driver and a gate electrode of the first transistor. A fourth transistor is coupled between a reference power supply and the gate electrode of the first transistor. The two capacitors are coupled between the organic light emitting diode and respective electrodes of the third transistor.
摘要:
An organic light emitting display includes a pixel unit including pixels coupled to scan lines, control lines, data lines, and first and second power sources, a control line driver for providing control signals to the pixels through the control lines, a scan driver for providing scan signals to the pixels through the scan lines, a data driver for providing data signals to the pixels through data lines, and a first power source driver for applying the first power source to the pixels. The first power source driver sets the first power source as a voltage in a low level in a first period in one frame period. The first power source is set as a high level voltage in second and third periods in one frame period. Therefore, it is possible to compensate for deviation in the threshold voltages generated between the driving transistors included in the pixels.
