Driving method for liquid crystal display

A multifigured or matrix-type liquid crystal display is driven by an applied voltage selected so that the effective value of the voltage applied to a display segment identified visually may have the maximum ratio to the effective value of the voltage applied to a display segment not identified visua...

Beschreibung
Zusammenfassung:	A multifigured or matrix-type liquid crystal display is driven by an applied voltage selected so that the effective value of the voltage applied to a display segment identified visually may have the maximum ratio to the effective value of the voltage applied to a display segment not identified visually. The multi-figured display can be driven as an X-Y matrix by coupling together the corresponding segment electrodes of each figure and sequentially actuating the common electrode of each figure. In a matrix-type liquid crystal display, the respective row electrodes of each digit would be coupled together, and the column electrodes sequentially actuated, to likewise define an X-Y matrix. In such an X-Y matrix-type liquid crystal display having N electrodes sequentially actuated, the applied voltage may be predetermined so that the voltage applied across a region of the liquid crystal material between said electrodes to be rendered visually identifiable may be ( 2ROOT N + 1) times as high as the voltage applied to a region of the liquid crystal material between said electrodes which is not rendered visually identifiable.
