Abstract
The present application provides an AMOLED pixel driving circuit and a driving method thereof. The AMOLED pixel driving circuit employs a 6T1C pixel driving circuit with a specific driving timing to effectively compensate the threshold voltage to drive the thin film transistors and stabilize the current flowing through the OLED, to ensure uniform luminance of organic light emitting diodes and improve the display effect of the image. Meanwhile, the combination of the N-type thin film transistor and the P-type thin film transistor to reduce the number of the thin film transistors and the scan control signals to simplify the structure of the pixel driving circuit and increase the luminous area.
