Abstract

Abstract : This work proposes a new active‐matrix organic light‐emitting diode (AMOLED) pixel circuit using an in‐pixel mobility compensation technique. Moreover, the circuit can compensate for both power line voltage drop and threshold voltage variation. Thus, it is suited for backplanes utilizing p‐type low‐temperature polycrystalline‐silicon thin‐film transistors (LTPS TFTs). Simulated results demonstrate that the compensation functions are succeed at a Full HD (1920×1080) resolution with a 60 Hz frame rate. The current error rates of power line voltage drop and threshold voltage variation are all below 3%, and those of mobility variation are below 6.5%.
