Liquid Crystal Display Matrices, Drive Schemes and Bistable Displays

Liquid Crystal Display Matrices, Drive Schemes and Bistable Displays... 

As discussed in previous sections, cholesteric liquid crystals exhibit two bistable states at zero field the reflecting planar state and the non-reflective focal conic state. They can be used to make multiplexed displays on passive matrices. In this section, we consider the drive schemes for the bistable Ch displays.
