The pixel internal compensation circuit comprises: first TFT (T1), with gate connected to third control signal (SCAN3), source and drain connected to data voltage (Vdata) and first node (A); second TFT (T2), with gate connected to first node (A), source and drain connected to second node (B) and high voltage power source (OVDD); third TFT (T3), with gate connected to first control signal (SCAN1), source and drain connected to first node (A) and reference voltage (Vref); fourth TFT (T4), with gate connected to second control signal (SCAN2), source and drain connected to second node (B) and initial voltage (Vini); capacitor C1, with two ends connected to first node (A) and second node (B); OLED, with anode connected to second node (B), and cathode connected to low voltage power source (OVSS). The invention provides a corresponding driving method. The invention uses parallel driving mode to effectively increase sensing time of threshold voltage compensation to improve compensation effect."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pixel internal compensation circuit and driving method","description":"The invention discloses a pixel internal compensation circuit and riving method.
