摘要： A liquid crystal display apparatus having scanning electrodes, data electrodes, and ferroelectric liquid crystal material placed between the scanning electrodes and the data electrodes. Scanning signals are applied sequentially to the scanning electrodes to select a scanning electrode. Data signals are applied in synchronization with the scanning signals to place a voltage at the intersection of the data electrode and the selected scanning electrode which will place the ferroelectric material at the intersection into the desired optical state. The scanning signals and the data signals are such that pixels located at the intersection of the non selected scanning electrodes and data electrodes receive an AC voltage superimposed onto a DC voltage. Pixels on selected scanning electrodes may also receive the AC voltage superimposed onto the DC voltage. The DC voltage has its polarity inverted with every vertical scanning period.

摘要： A technique for driving a liquid crystal apparatus having an effective display area and a non-display unit area is provided. When a bistable liquid crystal element is used, a voltage must be continuously applied to the non-display unit area to maintain a uniform white or black display state. Durability of the non-display unit is particularly desired. In this invention, the non-display unit includes first and second stripe electrodes disposed perpendicular to each other. First and second drive bipolar pulses are respectively applied to the first and second stripe electrodes with a phase difference between these bipolar pulses.

摘要： A liquid crystal display panel includes a pair of substrates having thereon scanning electrodes and data electrodes so as to form an electrode matrix, and a chiral smectic liquid crystal disposed between the scanning electrodes and data electrodes to form a plurality of smectic layers each including a plurality of liquid crystal molecules. The scanning electrodes and data electrodes are driven to define an effective display region and a frame-like fixed or semi-fixed pattern display region disposed outside the effective display region and extending along at least one side of the display panel. The smectic layers of the chiral smectic liquid crystal are aligned to extend in a direction which is non-parallel with the extension of the frame-like fixed or semi-fixed pattern display region so as to obviate the occurrence of cell thickness irregularity and liquid crystal voids.
