Abstract
The simulation model of short time image sticking (IS‐ST) of AMOLED displays was established. The impact of black plane circuit pixel design and work voltage had been studied. Pixel with good simulated IS‐ST had been optimized by decreasing the parasitic capacitance of M3 node and VDD line (C_M3_VDD) and the Length of switch TFT (TFT L). And IS‐ST also can be improved by Reducing the L0 gray data voltage (VGMP) and Vinit voltage (Vinit). All the solutions proposed above had been applied on our AMOLED display product, thus reaching the achievement that IS‐ST value decreases from 8 JNCD to 5.5JNCD at 0s.
