Each of the intra-pixel circuits includes a signal loading module, a driving transistor and an organic light emitting diode. Each of the signal loading modules is configured to store an image data signal and the threshold voltage of the driving transistor as a drive signal and load the drive signal to the gate of the driving transistor in a signal loading phase, and to control the driving transistor by the drive signal stored in the signal loading phase and a signal at a source of the driving transistor to drive the organic light emitting diode to emit light in a light emitting phase. The external circuit is configured to load a first power supply signal to the source of the driving transistor in the light emitting phase."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Organic light emitting diode pixel driving circuit and display device","description":"An organic light emitting diode pixel driving circuit includes an external circuit and multiple intra-pixel circuits.
