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%.
