摘要： A light modulating device comprises a plurality of data electrodes, a plurality of strobe electrodes, pixels at the intersections of the strobe and data electrodes, and addressing means for supplying data signals to the data electrodes in successive data selection periods and for supplying strobe signals to the strobe electrodes to set the transmission levels of the pixels in dependence on the data signals supplied to the pixels during each data selection period. Each pixel comprises a pair of subelements, and the addressing means is arranged to address the subelements of the pair by 1:3 spatial dither and to supply different strobe signals to each of the subelements during different bits of 1:1 spatial or temporal dither within the same data selection period. The transmission level of each subelement is determined by the data signal applied to the subelement in the data selection period in association with the strobe signal applied to the corresponding spatial or temporal dither bit.

摘要： A ferroelectric liquid crystal device includes a layer of ferroelectric liquid crystal material contained between a pair of substrates, a first plurality of electrodes and a second plurality of electrodes defining a plurality of addressable liquid crystal pixels. A driving arrangement is provided for applying a first signal (Strobe) in succession to the first plurality of electrodes and for applying a plurality of second signals (Data) simultaneously to the second plurality of electrodes. The plurality of second signals are arranged to include non-rectangular wave signals which have a lower harmonic content than a rectangular wave. Non-uniform heating of the device as a result of the application of the second signals (Data) is reduced with consequent improvement in device performance.

摘要： A ferroelectric liquid crystal display includes data electrodes connected to a data signal generator and strobe electrodes connected to a strobe signal generator. The strobe signal generator supplies strobe signals in sequence to the strobe electrodes within a plurality of consecutive time slots and the data signal generator supplies data signals simultaneously and in synchronism with the strobe signals so as to refresh sequentially the rows of pixels formed at the intersections of the data electrodes and the strobe electrodes, each pixel having at least two switching thresholds. Each of the strobe signals comprises a strobe pulse within a corresponding one of the time slots, the strobe pulse being preceded by a pre-pulse which reduces the effects of pixel patterning caused by refreshing the previously refreshed row of pixels. The pre-pulse extends within a time slot preceding the corresponding one of the plurality of consecutive time slots. The duration of the pre-pulse is greater than the duration of one of the plurality of consecutive time slots.
