摘要
Abstract
With the development of liquid crystal display technology,the higher PPI is,the smaller pixel is.The improvement of transmittance is an important issue.Compared with positive liquid crys-tal display,negative liquid crystal display has high transmittance,good color shift and display quality, so the negative liquid crystal is used in the main liquid crystal display,such as IPS and FFS modes. Nevertheless,for the physical characteristic of negative liquid crystal itself,the image sticking (IS)is more serious than positive crystal liquid,especially the area nearby the IC bonding.In order to im-prove the afterimage,we measured the different data,such as the temperature and common voltage (Vcom)of the serious and slight area in the sample cell,and we found that theVcom voltage has different shift in the serious and slight area.The influence factors of IS were analyzed,and improvement meth-od was proposed and it is effective to reduce the image sticking.关键词
