Abstract
An organic light emitting diode (OLED) pixel driving circuit and an OLED display are provided. The OLED pixel driving circuit includes a first thin-film transistor (TFT), a second TFT, a third TFT, a fourth TFT, a fifth TFT, a sixth TFT, a capacitor, a first OLED, and a second OLED. A drain of the third TFT is connected to an anode of the first OLED, a cathode of the second OLED, and a source of the sixth TFT. A drain of the fifth TFT is connected to a cathode of the first OLED, an anode of the second OLED, and a source of the fourth TFT. A drain of the sixth TFT and a drain of the fourth TFT both receiving a power supply negative voltage.
