Apparatus and method for driving a ferroelectric liquid crystal panel

摘要

A ferroelectric liquid crystal panel (1) including a plurality of scanning electrodes (Li), a plurality of signal electrodes (Si) crossing the scanning electrodes, a ferroelectric liquid crystal material having two stable orientation states corresponding to different memory angles and provided at intersections of the plurality of scanning electrodes and the plurality of signal electrodes to form a plurality of pixels (Aij) is driven. The plurality of pixels each have a first threshold characteristic regarding a voltage for switching a display state of the pixel into a non.display state and a second threshold characteristic regarding a voltage for switching the non-display state of the pixel into the display state. An apparatus for driving the ferroelectric liquid crystal panel includes temperature detection means (28) for detecting an operation temperature of the ferroelectric liquid crystal panel; and signal output means for outputting a driving signal based on a field frequency fixed at a prescribed reference frequency and a frame frequency determined in correspondence with the operation temperature of the ferroelectric liquid crystal panel detected by the temperature detection means, and writing the driving signal into each of the plurality of pixels at a writing time corresponding to a response time of each of the plurality of pixels changing in accordance with the operation temperature. $$
