In, pixel electrode 101 is spaced in the horizontal direction with public electrode 102, in vertical direction across dielectric
103.Liquid crystal molecule 301 is controlled by the horizontal component of electric field E between pixel electrode 101 and public electrode 102, according to
The size of electric field E controls the different ordered states of liquid crystal molecule 301, thus controls the display effect of liquid crystal indicator.
Typically, in IPS liquid crystal indicator, pixel electrode 101 and public electrode 102 are transparent conductive film, and all
