Co-ordinate addressing of liquid crystal cells |
摘要 |
In an active back-plane coordinate addressed liquid crystal cell whose pixels are set into one state by the application of a unidirectional potential across the thickness of the liquid crystal layer, and into the opposite state if the direction of the applied potential is reversed, refreshing is carried out in two sequential stages in order to avoid cumulative charge imbalance effects. In one stage the pixels are set to their required states, whereas in the other stage they are set to the inverse of those states.
