Abstract
Although LCDs are the leading technology for flat panel displays, their energy efficiency is low. One way to improve the energy efficiency is to decrease the driving frequency when static images are displayed. As the driving frequency is decreased, the transmittance of the display may vary with time, known as flickering. We carried out both experimental and simulation studies to investigate the origins that cause the flickering problem. Our results show that flexoelectric effect caused by non-uniform liquid crystal director configurations and ions in the liquid crystal are the main factors responsible for the flickering. We quantitatively analyzed the flickering caused by the two factors.
