Inter-electrode coupling phenomena and their influences on crosstalk defects are theoretically studied in thin-film-transistor liquid crystal displays (TFT-LCDs). The proposed mechanism for crosstalk defects is confirmed through experimental performance. The theory and the experimental results show that inter-electrode coupling is significant in recent low-cost TFT-LCD panels, resulting in strong signal distortion in storage and common electrodes. The signal distortion induces not only strong horizontal crosstalk but also large luminance deformation.
