Abstract:
The present disclosure relates to a pixel driving circuit and an organic light-emitting diode (OLED) display having the pixel driving circuit. The pixel driving circuit adopts a 6T2C (six transistors and two capacitors) structure to compensate a threshold voltage of the driving thin film transistor (TFT) in the pixel. As such, a current passing through the OLED may not be related to the threshold voltage of the driving TFT. So as to eliminate the improper image-displaying of the OLED display resulting from the drifting of the threshold voltage of the driving TFT.

Claim (Index 1):
A pixel driving circuit, comprising:\n a first thin film transistor (TFT), a second TFT, a third TFT, a fourth TFT, a fifth TFT, a sixth TFT, a first capacitor, a second capacitor, and an organic light-emitting diode (OLED); a gate of the first TFT electrically connecting to a first node, a source of the first TFT electrically connecting to a second node, and a drain of the first TFT electrically connecting to a third node; a gate of the second TFT being configured to receive emission controlling signals; a source of the second TFT being configured to receive initializing signals or data signals, and a drain of the second TFT electrically connecting to the second node; a gate of the third TFT being configured to receive the emission controlling signals, a source of the third TFT being configured to receive a positive voltage of a power supply, and a drain of the third TFT electrically connecting to the second node; a gate of the fourth TFT being configured to receive first scanning signals, a source of the fourth TFT electrically connecting to the third node, and a drain of the fourth TFT electrically connecting to the first node; a gate of the fifth TFT being configured to receive second scanning signals, a source of the fifth TFT electrically connecting to the second node, and a drain of the fifth TFT electrically connecting to the first node; a gate of the sixth TFT being configured to receive the emission controlling signals, a source of the sixth TFT electrically connecting to the third node, and a drain of the sixth TFT being configured to receive a negative voltage of the power supply; one end of the first capacitor electrically connecting to the first node, and the other end of the first capacitor electrically connecting to the second node; one end of the second capacitor electrically connecting to the first node, and other end of the second capacitor being grounded.
