Electrical origin and compensation for two sources of degradation of the spatial frequency response exhibited by liquid crystal displays

In this paper we give quantitative evidence for the electrical origin of two optical phenomena exhibited by commercial liquid crystal displays (LCDs) which affect its performance in spatial light modulation applications such as programmable diffractive optical elements (DOEs). These two optical phen...
