摘要:
The invention relates to a driving method permitting simple time sharing driving of ferroelectric liquid crystal matrix panel at high scanning frequency and high multiplexing ratio. A predetermined pulse is applied to a scanning electrode when another scanning electrode is selected to reset the pixel. The pixel is inverted or kept by the action of a pulse applied to the pixel when selected and, under this condition, a desired brightness is written in a short scanning period. Besides representation a number of grey levels is obtained by multiple scanning at reset timing varying with scanning.

摘要:
The present invention relates to an improved driving method capable of achieving high-quality display even in simple matrix addressing for a ferroelectric liquid crystal matrix panel at a high multiplex ratio. Pulses of a frequency higher than that of a scanning voltage in an addressed condition are applied to a scanning electrode in a non-addressed condition to gain either surface stabilizing effect or AC field stabilizing effect, hence ensuring high-contrast display. And the panel is so driven that the temporal average of the voltage applied to each pixel becomes zero, thereby averting deterioration of the liquid crystal.
