摘要： A display apparatus which is not adversely affected by a change in the drive waveform or environmental conditions. The display apparatus include a display device, a temperature detection device for detecting the temperature of the display device, and control means that controls the drive conditions for display device. The control means switches a driving waveform based on data from the temperature detection device. The effective value of a selection pulse is preferable changed simultaneously with the waveform switching. The waveform switching may be performed in during a temperature rise rather then during a temperature fall, and may be forbidden for a prescribed period after a waveform switching. The waveform switching may be also be performed between two types of waveforms including or not including a pause period.

摘要： A liquid crystal device including a chiral smectic liquid crystal disposed in a bistable alignment state including a first and a second stable state showing an asymmetrical threshold characteristic can be driven for a binary display according to a matrix drive scheme with an improved drive margin. The liquid crystal device is driven so that the liquid crystal is first reset into a less-stable first state regardless of display data and then selectively switched into a more-stable second state depending on given gradation data. The chiral smectic liquid crystal may be disposed in a planar smectic layer structure free from bending.

摘要： A display panel includes a matrix of pixels each constituted by a pair of oppositely disposed electrodes and a liquid crystal disposed between the electrodes. A current signal, particularly one associated with inversion of spontaneous polarization of the liquid crystal is detected at plural pixels. The display panel is driven by applying drive signals thereto while correcting the drive signals based on the detected current signal. As a result, a threshold distribution typically attributable to a temperature distribution on the display panel is accurately compensated for. The display system thus constituted is particularly useful for gradational display.
