    摘要: A high-speed responsive liquid crystal optical device with improved light transmissivity is provided. The device includes a liquid crystal panel including an optically active liquid crystal material having dielectric anisotropy which becomes zero at a crossing frequency ("fc") of 100 KHz or below. The dielectric anisotropy of the liquid crystal is positive at frequencies lower than fc ("fl") and negative at frequencies higher than fc ("fh"). Crossed polarizers are disposed on each side of the liquid crystal panel. A liquid crystal driving circuit selectively applies a signal of a frequency fh to open the device and a signal of a frequency fl to close the device.The optical device is particularly well suited for use as a light valve in a printer device. Response time within 1 m sec. permits a printing speed of 10 prints of A4 size to be produced per minute with a resolving power of about 10 dots per 1 m/m. This amounts to a printing speed of approximately 500 lines in one second with each line being written into m sec. or less. The optically active nematic liquid crystal is a composition comprising a optically inactive nematic liquid crystal and an optically active liquid crystal material added thereto.

    摘要: A mechanism for driving a matrix liquid crystal display which compensates for cross talk due to changes in temperature is provided. A matrix liquid crystal display has two substrates and a liquid crystal layer sandwiched between the two substrates. A group of common electrodes is formed on one substrate. A group of segment electrodes is formed on the other substrate. The common electrodes intersect with the segment electrode. A voltage is provided at the common electrodes and segment electrodes to produce a voltage waveform for driving the liquid crystal. A voltage waveform compensation circuit changes the voltages waveform in accordance with the pattern of drawings or characters to be displayed in the liquid crystal display device to produce the desired display and in accordance with at least one of an ambient temperature and a temperature of the liquid crystal display.
