An Overview of Wide-Viewing-Angle LCD Using Inter-Digital Electrodes

摘要

We have compared the performance of wide-viewing angle technology using interdigital electrodes, which are in-plane switching (IPS), fringing field switching (FFS) and finger on plane (FOP). What we have found is that IPS has the fatest response, FOP has the largest proess window, and FFS can provide the similar transmittance as FOP but with more difficult process. The basic properties of these technologies will be reviewed in this paper.
