Matrix array bistable device addressing
A ferroelectric liquid crystal display comprises a matrix of pixels addressable by first and second sets of electrode tracks crossing one another at the locations of the pixels. The pixels ale addressed by applying data pulses to the first set of electrode tracks and strobe pulses to the second set...

| description | A ferroelectric liquid crystal display comprises a matrix of pixels addressable by first and second sets of electrode tracks crossing one another at the locations of the pixels. The pixels ale addressed by applying data pulses to the first set of electrode tracks and strobe pulses to the second set of electrode tracks to switch certain pixels selected by the data pulses from a first state to a second state under the effect of the voltage difference between the data pulses and the strobe pulses, and blanking pulses are applied to the second set of electrode tracks to set the pixels to the first state in advance of the application of subsequent strobe pulses to switch selected pixels from the first state to the second state. Each blanking pulse includes a blanking portion of one polarity adapted to switch the pixels to a fully switched reunion of the first state and a trailing portion of the opposite polarity adapted to assist relaxation of the pixels from the fully switched region of the first state to a relaxed region of the first state from which rapid switching of pixels to the second state is possible during application of a subsequent strobe pulse. |
