— Optical flicker is one of the artifacts of color STN‐LCDs and is related to the electrical asymmetry in LCD panels. The transient‐current asymmetry was observed to have a linear correlation with the internal DC offset of LC panels. The asymmetric cell structure of LC panels with a single topcoat layer leads to the asymmetry. The interface effect between different layers in an LC panel plays an important role in this phenomenon. Based on experiments, an improved RC network model was introduced to describe the mechanism.
