摘要： A driving method for a liquid crystal display element including L row electrodes and K column electrodes in which two kinds of data, data corresponding to a logical "0" and data corresponding to a logical "1", are used to display gray shades. The row electrodes are divided into row electrode subgroups which are selected as a batch. When the row electrode subgroups are selected, they have a positive voltage level with respect to a non-election voltage and a negative voltage level with respect to a selection voltage. A matrix of column vector components in which row voltages are time-sequentially arranged form a display cycle in each of the row electrode subgroups, and such a matrix has orthogonality. Row voltages are dispersively applied in a display cycle in each of the row electrode subgroups. Further, a number of column vector components K is related to a number of row electrodes L such that K is a minimum value satisfying the orthogonality and L is.ltoreq.2.sup.P =K, where K, L and P are integers. A gray shade is then effectuated by displaying a plural number of ON and OFF signs at a specified ratio.

摘要： A liquid crystal display device restraining display defects even in a structure having a potential difference between an externally-connected electrode potential and the mean potential of the drive waveform of a liquid crystal material. An electrostatic charge stored in the vicinity of a liquid crystal layer of the liquid crystal display device as a result of the potential difference between an externally-connected electrode potential and the mean potential of the drive waveform of the liquid crystal material is dispersed by employing a capacitor or an arrester connected to ground. Accordingly, discharge of the stored charge is facilitated, and occurrence of display defects is restrained.

摘要： Data transfer is performed to and from a host computer using a first block as the minimum unit. Data transfer is performed to and from a storage area using a second block as the minimum unit. A second block set of the storage area stores data obtained from performing data conversion processes that change the size of the data itself, with a first block set as the unit. Here a correspondence relationship is generated between the first block set and the second block set. In response to a read request from the host computer, a second block set, which corresponds to the first block set that includes the first block that is requested, is read, a reverse-conversion process is performed, and the data is sent to the host computer.
