    摘要： A driving method of a liquid crystal display element having plural numbers of scanning electrodes and data electrodes where a J.times.L number (J and L are each integers.gtoreq.2) of scanning electrodes are divided into J subgroups each having L scanning electrodes so that the subgroups are selected and driven as a batch. The subgroups are selected while the following conditions are satisfied: (1) in L=k.multidot.N.multidot.T/.tau., a value satisfying k=10-250 is determined, where L is the number of row electrodes selected, N is the total number of row electrodes, T is a selection time of a single scanning electrode and .tau. is an average response time of a liquid crystal display element; (2) in a selection time, a voltage is applied to the scanning electrodes in a positive or negative direction with respect to an intermediate voltage, and in a non-selection time, the intermediate voltage is applied to the same, (3) for a selection voltage matrix, an orthogonal matrix A having L rows and elements of +1 and -1 which correspond respectively to a positive voltage and a negative voltage, is selected, and (4) in a selection time of the scanning electrode subgroups, application of the voltage is so made that elements of a column vector in the selection voltage matrix correspond to the amplitudes of the voltage to the scanning electrodes forming the scanning electrode subgroups.

    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： An image display device having an electro-optical medium interposed between a pair of electrode substrates composing a matrix electrode, a driving circuit for driving the electro-optical medium by selectively applying a voltage on the matrix electrode and a reference voltage generator for supplying the driving circuit with a predetermined driving voltage. A noise compensating circuit is interposed between the driving circuit and the reference voltage generator, the noise compensating circuit detecting a noise in a voltage supplied from the reference voltage generator to the electro-optical medium at a predetermined noise detecting position, forming a noise compensating voltage having a first polarity reverse to a second polarity of the noise by using the noise, and supplying the noise compensating voltage to the driving circuit.
