A drain of the second transistor is coupled to a cathode of the organic light-emitting diode, and an anode of the organic light-emitting diode is couple to a power line. A source of the second transistor is respectively coupled to drains of the third transistor and the fourth transistor. A source of the third transistor is coupled to a gate of the second transistor, and gates of the third transistor and the fourth transistor receives a compensation control voltage. A source of the fourth transistor is grounded. A shift of the threshold voltage of an AMOLED can be compensated in an embodiment of the present invention, whereby uniformity between a picture and grayscales of the organic light-emitting diodes can be improved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pixel driver circuit, display panel and driving method for the pixel driver circuit","description":"A pixel driver circuit including a first transistor, second transistor, third transistor, fourth transistor, first capacitor, second capacitor, and organic light-emitting diode is provided.
