The AMOLED pixel driving circuit is disposed with a voltage switching module corresponding to each row of sub-pixels, and the voltage switching module is connected to a corresponding row of sub-pixels and scan line corresponding to the row of sub-pixels. The scan signal on the scan line controls the corresponding voltage switching module to provide different power supply voltages to the row of sub-pixels when the switching TFTs in the corresponding row of sub-pixels are turned on and off, thereby compensating for the voltage difference change caused by the parasitic capacitance between the drain and the gate of the switching TFT when the switching TFT changes from on to off, ensuring a stable current flowing through the OLED, and improving the display consistency of the sub-pixels to ensure display quality."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"AMOLED pixel driving circuit and driving method","description":"The invention provides an AMOLED pixel driving circuit and method.
