摘要

This paper presents a new driving scheme for active-matrix organic light-emitting diode displays. A pixel circuit based on this driving scheme was developed to compensate for the threshold voltage and mobility variations of low-temperature polycrystalline-silicon thin-film transistors (TFTs), eliminate image flickering and current-resistance voltage drops, and suit ultrahigh-definition (UHD) resolution applications. A new gate driver with a concise 6T1C structure is also proposed to realize the driving scheme in practice. Fabricated TFTs and OLEDs were measured to establish models. Simulations using these models demonstrate that the proposed pixel circuit achieves uniform OLED current regardless of undesirable influences at UHD resolution.
