摘要： A display device and method driving a display device makes use of the dynamic variation in the brightness of a surface mode liquid crystal device cell having a liquid crystal layer with a non-zero twist angle. The liquid crystal layer is switched before the equilibrium value of the brightness has been reached, so as to make use of the non-equilibrium increased brightness and so increase the brightness of the display.

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 surface mode liquid crystal device is made by forming a cell containing a mixture of a liquid crystal and a pre-polymer. An electric field is applied across the cell to arrange the liquid crystal in a predetermined surface mode state, such as the V state in the case of a pi-cell configuration. The liquid crystal is held in this state by the field while the pre-polymer is polymerized or cross-linked, for instance by ultraviolet irradiation. The electric field is then removed. The polymer stabilizes the predetermined surface mode state, for instance preventing relaxation of the V state to twist or splay state in the pi-cell configuration.

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 twisted liquid crystal device includes a liquid crystal layer and first and second alignment layers disposed in opposite sides of the liquid crystal layer. The first and second alignment layers have respective alignment directions which are mutually inclined. A first linear polarizer is disposed on the opposite side of the first alignment layer to the liquid crystal layer. Electrodes apply a variable voltage across the liquid crystal layer which has a twisted liquid crystal structure. The liquid crystal layer is arranged for operation in surface switching mode with first and second regions of the liquid crystal layer adjacent the alignment layers being mutually optically de-coupled so as to define, within the liquid crystal layer when in use, a pair of separate, active optical retarders having mutually inclined optic axes.

摘要： An addressable matrix display comprises an addressable matrix of pixels, a first set of electrode tracks on one side of the matrix and a second set of electrode tracks on the other side of the matrix. The sets of electrode tracks cross one another at the locations of the pixels, and the pixels are switchable by the application of respective switching waveforms to the electrode tracks. Furthermore at least one of the electrode tracks has a resistance which varies along the length of the electrode track in order to provide increased temperature uniformity over the display due to power dissipation during switching by the switching waveforms applied to the electrode tracks. More particularly the resistance in an intermediate section of the electrode track is greater than the resistance in two end sections of the electrode track.
