Improvement of Dark State Light Leakage in ADS Mode LCDs

摘要

In the paper, we have improved the dark state light leakage caused by glass retardation from average level 2.4 to level 1.2 in ADS mode LCDs. We proposed several methods to reduce light leakage, including how to reduce stress between PS and array substrate and LC optical retardation Δnd optimization. All these proposed methods can be explained by glass stress and photo elastic theory.
