Abstract

Official abstract text for this publication.

A voltage-driven pixel circuit, a driving method thereof and a display panel including the voltage-driven pixel circuit are disclosed. The voltage-driven pixel circuit comprises a driving transistor, a retaining transistor, a switching transistor, a compensating transistor, a storage capacitance and an OLED device. The technical solutions disclosed here compensate for the unevenness of the threshold voltage of the N-type TFT transistors and OLED efficiently.
