There is provide a driving method for the pixel driving circuit, and it comprises charging the storage capacitor (Cs); discharging the storage capacitor (Cs), so that a voltage difference exists between voltages at two terminals of the storage capacitor (Cs); changing the data voltage (Vdata), so that the voltages at the two terminals of the storage capacitor (Cs) vary as same as variations in the data voltage (Vdata); and driving the organic light emitting diode (OLED) to emit light. The above pixel driving circuit and the driving method can realize a compensation on the threshold voltage for the driving voltage of the driving transistor (DTFT), and in turn an effect on operating current of the organic light emitting diode (OLED) caused by the threshold voltage is eliminated. There is also provided a display apparatus comprising the above pixel driving circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pixel driving circuit, driving method thereof and display apparatus","description":"There is provide a pixel driving circuit, and the pixel driving circuit comprises a driving transistor (DTFT), organic light emitting diode (OLED) connected with the driving transistor (DTFT), a first","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9691327","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
