摘要： A liquid crystal display device which carries out matrix driving of a liquid crystal layer by applying AC pulses to the liquid crystal layer through a plurality of scan electrodes and a plurality of data electrodes which face and cross each other. A method of driving such a liquid crystal display comprises a reset step of applying a reset pulse to liquid crystal to reset the liquid crystal to an initial state, a selection step of applying a selection pulse to the liquid crystal to select a final state of the liquid crystal, an evolution step of applying an evolution pulse to the liquid crystal to cause the liquid crystal to evolve to the selected final state. The reset pulse and the evolution pulse have alternating cycles which are longer than that of the selection pulse, and the adjustment of the alternating cycles of the reset pulse and of the evolution pulse are made by changing the pulse waveform applied to each of the scan electrodes.

摘要： A method for driving an optical write device, in which a time for formation of a pixel is divided into a plurality of periods, and tone level control based on multi-tone image, data is performed in each of the periods. For example, the time for formation of a pixel is divided by applying a train of pulses with widths weighted in the ratio of 4:2.1, and in each duration of the pulses, a clock signal for 64 tone levels is given.

摘要： A PLZT optical shutter array includes an optical shutter array, a driving circuit, a temperature compensating circuit, an IC control unit, a driving IC and a temperature sensor. Temperature of the optical shutter array is detected by the temperature sensor, and based on a voltage representing the temperature and a reference voltage for driving optical shutter element, a driving voltage for the optical shutter element is generated in the temperature compensating circuit. The driving voltage is applied to the optical shutter element through the IC control unit and a driving IC. As a result, a voltage applying apparatus for a light signal emitter which has a simple structure and allows cost reduction is provided.
