A pixel drive circuit of an OLED display. A 6T2C structure is adopted. The pixel drive circuit comprises at least a scan switching transistor TFT1, a drive transistor TFT2, a first compensation switching transistor TFT3, a second compensation switching transistor TFT4, a first reset switching transistor TFT5, a second reset switching transistor TFT6, an organic light emitting diode (OLED), a coupling capacitor C1 and a storage capacitor C2. By means of the drive circuit, drifting of the threshold voltage of the drive transistor can be compensated, and therefore the uniformity of the gray level and the image of the OLED is improved. |
