Generally, an organic light-emitting display device may include a driver and a plurality of pixels, and each pixel may correspond to one pixel circuit, wherein the driver may generate a drive signal, and the drive signal may be transmitted in a plurality of pixel circuits. Each pixel circuit is scanned and data is written into each pixel circuit so that the light-emitting diodes in the pixel circuit emit light, and the entire display device emits light.
However, in practical applications, when the drive signal is transmitted from one pixel circuit to another, the drive signal may inevitably have a delay due to the resistance and the capacitance of a signal line in the pixel circuit. As the resolution of the organic light-emitting display device continues to increase, effective time for scanning each pixel by the drive signal is continuously shortened. Thus, in the case where the drive signal is delayed, the writing of data into the pixel is seriously affected, thereby affecting normal display of the entire display device.
