— The source (or data) bus‐line to common (or backplane) electrode coupling effect in TFT‐LCDs has been investigated through experiment and simulation using a new model. The important feature of this simulated model is that the common electrode consists of a network of discrete resistors. The horizontal crosstalk is caused by this coupling effect, and the mechanism of the crosstalk has become clear by the simulation of 5‐in. TFT‐LCDs. By adopting this simulation, useful information for large‐area TFT‐LCD designs can be obtained. As an example, this simulation has been performed for 10‐ and 15‐in. TFT‐LCDs and the requirement for a common resistance has been illustrated.
