ABSTRACT:
The waveforms of driving signals used for driving a display device which comprises a smectic liquid crystal and matrix electrodes including scanning electrode groups and information electrode groups are changed according to the ambient temperature in order to provide a satisfactory display in a wide range of temperatures. These types of the driving signals suppress unexpected inversion of the liquid crystal molecules at a low temperature and provide fast scanning at a high temperature.
